Thanks for the review... where did you get your 25 cal barrel? have you had a chance to kill anything with it yet?
all of these rounds based off the 556 are pretty cool. |

I ordered the barrel blank from Brownells (Shilen), used 320pf's reamer, TP555 turned and chambered the blank. Brent has been talking about having a group of them done and I may go for a longer one just for the fun of it. I'll have to wait for hunting season to come around but I will take this rifle out. By then I should have all of the loads worked out and be set to go. It should be a winner in the 150 yard range. |

Tag for effect. Thanks for sharing.
Definitely interested in a barrel...are your dies Hornady custom? |
|

Yup, never cared much about triggers until my 6.5Grendel build. Now I REALLY want a good trigger!! Interesting wildcat! Have fun!

...are your dies Hornady custom?
C-H/4D did the dies. That is the blessing with this rifle. Just the dies and a barrel. All of my loads have been made using once fired Lake City brass which is about as cheap as it gets. Using Pmags (20 round) and Brownells (30 round) has given me 100% without a single round failing to feed. |

This sounds like a great wildcat. I just jumped into the 6x45, but this sounds fun as well.

Will this round handle the Nosler BT 100 and 115gr bullets or are they too long to seat at magazine length?

Just looked up dies at http://www.ch4d.com/. At around $80.00, they're much less than others are charging for custom dies. Now I'm intrigued.
Definitely keep us posted if you or someone else decides to do a run of barrels. ETA: I think I would go for a 20". |
|

Interesting!
Like many others, I've always stayed away from wildcats because of the brass & die issues, and is it something I'm willing to mess with in the long run? This DOES seem like an easy way (cheap) to experiment. I'll be watching this thread closely, please keep us updated if someone decides to do a run of barrels. I'd like a 20" barrel (for antelope & cyotes). |
|
|
I would be interested in this calber as well. I am slowly converting most of my 223's AR's into other calibers. I will keep one, so that gives me oom to grow
If someone decides to do a barrel run, let me know... |
|
|
I am in for one of these barrels as well. Sounds like a great project.

I have been using the Speer 100 gr. BTSP and with the results I have been getting with accuracy I'll stay with them. I'm sure the Nosler BT 100's won't be a problem but I have not seen anything heavier that works with the magazine restriction. I guess the main thing with this wildcat is to start out knowing it's limits. It will not set the world afire but it does out class a standard .223 and makes a nice little carry package. If you like something different the 25-223 will fit the bill. Just looked up dies at http://www.ch4d.com/. At around $80.00, they're much less than others are charging for custom dies. Now I'm intrigued.
What's not to like. I'm just a poor photographer and I hate paying more than I have to. I just got back in from trying a load (it's nice having my range 200 yds. from the house.) 16" barrel Speer 100 gr. BTSP Win. Small Rifle primers Lake City brass Hodgdon H322 I started at 21.0 grains for 2190 fps avg. and worked up to 24.2 grains for 2482 fps avg. This about fills the case but it seems to be a reliable load without any pressure signs. I've played with the 1680 but after about 21.0 grains it seemed a llittle too hit or miss with the pressures. But hey, I've got awhile before I will try hunting with it. I will say that I'm really starting to like the AR (I've always been a "polished blue and walnut" type of guy). I've used them as photo props but finallly it is getting fun to shoot. |

Thank you sir, I'll give them a try.

If you like something different the 25-223 will fit the bill. The reason I ask is that I'm also looking at a 6.5MPC which will handle 120gr 6.5 bullets pretty well. I like the Nosler bullets as they have a pretty proven track record at the lower velocities achieved with these .223 wildcats. I'm just trying to best weigh out the options. I don't expect a .25-223 to replace the 6.8SPC and the 6.5Grendel. I know it will have limitations, I'm just trying to guage which if the 223 based wildcats will fit my needs (ok, desires) the best. I wish I could afford them all... So you think the 115gr bullet might be too long for this cartridge. What do you think about the 110gr Accubond? Would a round with the shoulder set back slightly, like the .25x40, better suit my needs with the longer bullets or would I lose too much velocity with the lower capacity and extra weight? |

From what I have been reading the .25x40 would be better suited to handle the longer and heavier bullets. But I can not speak for what velocities you will get with them since I have not tested them for myself. I will say that I had my eyes opened a bit a few weeks ago when I was testing chronographs. One brand would read almost exactly 50 FPS faster on every shot. Add that to the fact of how one barrel will react differently from the next and things can change rather fast when you are working up loads. I've been reloading since the 70's and always err on the safe side. If I have not tried it for myself I just don't feel qualified to advise you the best way to go.
If I had a reamer for one of Kurt's ?x40's I would have given them a try. They all seemed interesting but the 25-223 was the way to go with money and availability. I even looked at the 6.5 MPC but with only one source (one I thought was overpriced) I passed on it. |

Interesting wildcat..........can do nothing that the 6x45 already does.........IMHO one defeats the purpose of 223 based wildcats like the 6x45 by using heavy bullets.........the 6x45 shines with bullets in the 80-85 grain weight catagory.........heavier bullets are best served in the 243 Winchester case..............

I found same thing with the 6X45 round with the AA1680 limit seems to be about 20.5 grs with the 20" Rifle Gas Bbl.

While I like what I've seen on the 6x45 I think there are things the .25-223 does better. The .25 will fire an 85gr bullet at 2900fps based on Kurts data on the .25x40. I suspect the .25-223 would do just as well while the info I've found on the 6x45 indicates it will fire an 85gr bullet at 2500fps. That's a fairly substantial difference (1179 ft/lbs vs 1587 ft/lbs muzzle energy). While I understand that you pay a price in ballistic coefficient when you increase bore and maintain weight, there are definitely applications where that is a reasonable trade off. I think each of these rounds serves a purpose, if it didn't you wouldn't see so many different calibers still available, the market would have defined the best performing calibers and the rest would have just gone away (by caliber I mean actual bullet diameter, not a complete cartridge). ETA: The 6.5 MPC will push a 95gr bullet to 2800fps (1653 ft/lbs) while the 7.62x40 will push a 110gr bullet to 2700fps (1780 ft/lbs). It seems that every increase in bore diameter increases case efficiency and muzzle energy but generally at the expense of ballistic coefficient. All of them seem to like light for caliber bullets (not surprising with the magazine length restriction) and that becomes more evident the larger the bore. |

I for one don't tend to look at numbers like some folks do..........100 fps, oh yes, than it must be better.......I rountinely was getting 2700 fps out of a twenty inch AR with 80 grain Sierra SPBT bullets........
In 1973 the cartridge set a new IBS 200yard record of 0.3062. This in itself tells me the 6x45 is an accurate round.......There is no denying the BC of 6mm bullets............................ Like I said it is indeed another interesting wildcat...........I stand by my convictions.....It can't do anything more than the 6x45.............we will have to agree to disagree......... |

I'll grant you that going much heavier or futher in bullet diameter with the .223 case might make for some unacceptable trade-offs, but 2500 fps w/ a 100-grain bullet out of a 16-inch barrel definitely has me interested. At the same time, the 25-223 will have no problem with the 85-87-grain projectiles typically used by 6x45 shooters (I'll grant in advance that the .257 bullets will have a slightly lower BC than .243 of the same weight...BFD). Let's look at this yet another way...the .25-06 and .270 are both derived from the parent case and for all practical purposes occupy basically the same niche. Any deer hit with the .25-06's 120-grain .257 bullet vs. the .270's 130-grain .277 bullet (assuming proper placement) will be equally dead. Yet each cartridge is succesful in its own right, as each offers its own drawbacks and benefits. Same with 6x45 and 25-223. |

I agree that numbers aren't everying. I have no doubt that you have had significant success with the 6x45. I'm also not saying the .25-223 is better, worse, or the same. I'm just saying that they are different and both have their strengths. As a hunting round, I'd be more comfortable with the .25 because it can handle heavier bullets, but that is my preference and not intended to suggest you couldn't use the 6mm. |

Nothing wrong with that. The .25-.223 does "ring my chimes" and that alone is all I ask of it. I was looking for a 150 yard carbine that was easy to carry and had enough power for anything on my land (I have no desire to shoot any of my bears.) There are a lot of calibers and a lot of other firearms that would fill that need but this is the choice I made and at least I know I'll be the only one in my woods with one. |

What is the difference between the 25x223, and the 25x40? what is the length of the 25x223 brass?
|
|
|
About the only difference is the 25x40 has the shoulder set back and it is trimmed shorter. The 25-223 is just necked up in the resizing and then trimmed about 2mm to make sure it does not ride to high on the bullet when it is seated to fit into an AR magazine. This is about as easy as it gets for a wildcat. The advantage to the 25x40 is I think it will fit heavier bullets (over 100 gr.)
If I was a wealthy man I could try them all. (may not get much work done but it would be fun) |

so it is a 25x43

There are a lot of BC crunchers here so it was laid out for use up to the more slick 100gr Matchking, although I gravitate more to the 80TTSX as a all-around hunter, currently running over 3,000fps....and that's pretty fast for a slow bullet....usually stay at or under 100gr, point of diminishing return. The smaller case and geometry offer several advantages that I won't get into here but one being that it accelerates the rise to peak pressure allowing smaller charges of powder and achieving the same or better performance of its full-size cousin in shorter barrels.... |

I would just be supremely interested to see what one of these 25 cal wildcats could do with some of that uberpowder like they're running in the Mk318 ammo... other than increased performance in general, it would be very cool to get a 100gr bullet up to the velocity the Brits came up with in their study.

Now that I have my hands on one of your 7.62x40's (I picked it up from 87GN) I'm in the market to fill the gap between the .223 and the 7.62. I think I've got it narrowed to the .25x40 or the 6.5MPC. |

"I think I've got it narrowed to the .25x40 or the 6.5MPC." I am with you, the 6.5 MPC will be better at longer ranges on deer and hogs(out to 300 yards), but the 25 does not have to be fire formed.

The 6.5 MPC does not need to be fireformed...The 6.5 AR-TCU does, do to the steeper shoulder angle and less body taper. |

If you're talking about 300 yard killing envelope, why not use either the 6.5 Grendel or the 6.8x43 (SPCII)? |

If you're talking about 300 yard killing envelope, why not use either the 6.5 Grendel or the 6.8x43 (SPCII)? |

If you're talking about 300 yard killing envelope, why not use either the 6.5 Grendel or the 6.8x43 (SPCII)? And don't forget brass. With lighter projectiles some of these 223 based wildcats are getting very close to 6.5G and 6.8SPC performance. I'll grant you that they won't match them, especially with heavier bullets like the 123gr 6.5 bullet, but they only require a barrel change and brass is everywhere. That has merit to me. |

The 6.5 MPC does not need to be fireformed...The 6.5 AR-TCU does, do to the steeper shoulder angle and less body taper. so you can just run 223 brass through a 6.5 MPC resizing die and load? |

The 6.5 & 6.8 both sound interesting to me and I could handle the changing of the bolt and magazines (they are one time cost). It is the cost of brass that kills those two for me. USGI once fired is what makes these wildcats worth the effort.
At the same time, anything past my 150 yd self-imposed limit I'll pick up a .308 Win. |

This is about as easy as it gets for a wildcat. The advantage to the 25x40 is I think it will fit heavier bullets (over 100 gr.) If I was a wealthy man I could try them all. (may not get much work done but it would be fun) I wish it was that easy....... From the start the 25x40 was designed as a work-around for game management areas that did not allow .22 caliber center-fire cartridges.... It was not by luck or fluke that .25 cal was selected for the project, there was close to a decade of previous testing done on small cases similar to a PPC... There are a lot of BC crunchers here so it was laid out for use up to the more slick 100gr Matchking, although I gravitate more to the 80TTSX as a all-around hunter, currently running over 3,000fps....and that's pretty fast for a slow bullet....usually stay at or under 100gr, point of diminishing return. The smaller case and geometry offer several advantages that I won't get into here but one being that it accelerates the rise to peak pressure allowing smaller charges of powder and achieving the same or better performance of its full-size cousin in shorter barrels....

This is very interesting, I will be following this. I have thought about a 6.8 for a couple years now, but the cost of the brass has been the primary thing that has held me back. This may be just the thing. Thanks for the info guys.

The only real PITA is case trimming to length. But thats true for most 223 AR Wildcats. Some guys like to anneal the case as well, for extra case life...I usually buy pre-annealed cases. |

Let's not lose track of the most important issue here...how exactly does an individual like myself, who has neither a machine shop nor a gunsmith as a shooting/drinking buddy, procure a barrel with this chambering?
