Well,. almost finished! On that note, what type of iron sights are you guys using for this round? 5.56 sights or sights setup for 7.62x51? I have a scope on it now for group testing, but think I may want to install something that I can flip down and leave on with the scope. I run a Matech rear and YHM flip up on my 5.56 upper that I use on this gun. I like the Matech rear and would like to use it if it will regulate to this round even close. |

There's a BUIS calibrated for 7.62x51? All mine are just windage adjustable so I was unaware of one made for the larger caliber. My 7.62x40 doesn't even have a BUIS currently, it wears a 2-7x variable power scope. Regardless, any rear sight with calibrated elevation adjustment for 5.56 or .308 won't work. They are just too different in either velocity, ballistic co-efficient, or both. If there is one made for 7.62x39 that might be close, but I'm not aware of any such animal. |

Does H110 work with the Sierra 125 pro hunters? My barrel is a Wilson 16" 1-12 twist with a carbine gas system. I found some Vmax 110s locally and they shoot pretty well, but I don't think they will be the best choice for Minnesota whitetails. I know the Barnes bullets would probably be the best, but I want to use 1 load all the time and they are too expensive to shoot up just for the fun of it, so I was thinking the Sierras would be the way to go.

H110 should run fine in your CAR gas, mid-gas guns are pretty much limited to A1680. Try 21gr H110 and a OAL of 2.160". The Nosler 125gr BT is my favorite deer bullet. |

Finally broke the cherry on my build. Started with 21.5 gr of IMR4227, topped with a Sierra 125gr Pro Hunter.. All looked well so after cleaning stepped up 22 gr. Still looked good so I moved to 22.5 gr. At 22.5 I shot 2 rounds. Brass looked great but had one primer to come out. Other primer looked good. I am thinking loose primer pocket. The only other issue I had was the bolt would not hold open after last shot with any of the loadings. I am hoping it is the cheap 5 rd Pro Mag I was using. Gonna try with a standard mil-spec mag to see. I can live with the bolt not staying open with the promag as it was bought for deer season. It is a flush fit with the mag well so as to not catch on stuff in the stand. So far very happy. Now to zero the scope and bust out the crony.

Now to zero the scope and bust out the crony. which barrel are you using and carbine or mid gas? if it is mid gas you won't get bolt to lock back with 4227 unless you open up the gas port then you may be over gassed with 1680 |

Order, beg, borrow, steal AA1680 and love it |

I am using a WC fluted stainless 16" mid gas. I reckon I will have to break down and pay the haz mat and order a couple or three lbs of 1680. Oh well. I do love the way it shoots. Gonna be a nice light, negligible recoil, deer destroyer come season.

word is wilson will have an adjustable gas block in the next few months so then we can open up the port and use the adj. block so we can run all 3 powders.
my gun shoots the h110 good just don't lock bolt back or pick up next round. i get 100-125fps more out of it than 1680 but i don't like a single shot. |

That would be fantastic. I already keep a mess of H110 here for my M1 carbine. IMR 4227 is also easy to find on the shelf. Nobody near me stocks or can seem to get AA1680. An adjustable block would kick butt. I just hope it is a low pro style.

My 16" mid gas will run all three powders without a problem. I don't know the gas port size though, never measured it before putting the rifle together. ETA: I do have to run the faster powders at near max loads, where I can download the AA1680 quite a bit. |

i know what port mine is supposed to have. i am going to take my gas block off and check to see what it is. i might open it up a touch to see if it will work.
would hate to hurt the accuracy though cause this thing shoots. and i have taken both h110 and imr 4227 past max in my opinion and they still won't run. Originally Posted By Altair:

I find it quite amazing how efficient (per grain of powder) the 223 based wildcat rounds are from the 6.5mm/.264 to the 7.62mm/.308 bores, and how wide
a variety of powders can work with the various calibers, often beating larger case capacity rounds with less power needed, using cheaper brass, the same .223/5.56 standard components/parts. |

We just finished the first production run, but these are slated for the 458 project. Our new 5600 sq ft machine shop expansion should be up and running by June 20 or so and this will make a major difference in our production capacity. An adj block is great on a carbine gas, but your just going to be stuck with A1680 on the mid-gas guns. |

Got to the range today with my 18" poly x40 do do some hot load testing in fire formed cases. my fire formed cases hold 1 more grain of water than fresh cases.
velocities were great and no pressure signs for me but i don't think i can get much more powder in the case and it don't look like i need too. i ran my 110 vmax and 110 sierra varmiter bullets with 1680. wcc 11 cases and rem 7 1/2 primers sierra's were seated to 2.11 oal vmax's were seated to 2.25 –– .010 off the lands. all shots are off rest at 100 yards and at a rate of 1 shot every 2 seconds.

Bigdawg, your gun is shooting great. I'll have to try some of those 110 Sierra varminters. My gun still likes the H110 best for accuracy, but of course, won't function. With the 1680, it seems to like the Speer 125 TNT bullets a little better. Still not having the accuracy I would like to get out of it, but I have a few more test yet to do. Still gonna be a winner on deer and hogs!

Bigdawg, thanks for sharing your load data and range results. I'll be using some of it for my own loads soon.
Big Frank, my build is shooting accurately but not cycling properly as well. Have tried loads with 4227 and H110 w/o success. Even tried some WC factory ammo. Different gas blocks then an adjustable one from JP Enterprises. Also swapped out BCG, bolt, etc.... Just bite the bullet and ordered some 1680. From what I understand... that seems to be the key for a mid-length setup so will be trying that out next. |

I will say that if going to 26.7+gn 1680 use fire form cases and work up they are hot loads but no pressure signs in my poly barrel. and yes if you have a mid gas you are stuck with 1680 but as you can see with my last loads 2550fps with a 110gn bullet isn't too shabby |

Has anyone tried AA2200 in the mid-length gas barrels? If so, how did it compare to AA1680? Did it cycle the action?
I've not purchased a 7.62 x 40 AR yet, but AA2200 is showing good promise in the .458 Socom from my (limited) testing. It would be nice to be able to consolidate powder usage and enjoy the benefits that AA2200 has over AA1680. I apologize if this has been asked and answered before, but I did not see it. Thanks! |

I haven't tried this powder but I imagine velocity would suffer. It would prob cycle the rifle but the pressure would be too low for an acceptable velocity. |

It would be nice to be able to consolidate powder usage and enjoy the benefits that AA2200 has over AA1680. I apologize if this has been asked and answered before, but I did not see it. Thanks! no expert here but it may be a little slow for the 110gn bullets but may work with the heavier ones. if i can find some i will give it a try. i want to try some in my new 6.5pcc also. maybe wilson can comment on it? I anxiously await the results of your testing BIGDAWG. Thanks! just ordered some aa2200 from my local scheels should be here next friday. so i should have some data in a couple weeks. Please update the thread after you get some range time with the AA2200 please. I gotta see this! |

Yes, let us know how it goes... I use AA2200 for my 6.8 loads. Would be gr8 if I could consolidate powders for both 6.8 and 7.62x40.

Fantastic...I like the low SD's of that powder even though velocity suffered a bit it seems decent. Can't wait to the the higher charges.

Just got done building my 7.62x40. Heading to the range this weekend to break in the barrel :)
I have a question about reloading. My dad use to reload for his 30 carbine but doesnt anymore so he gave me a ll his remaining bullets, brass etc. I have about 400 of the seirra 110gr round nose bullets and i'm wondering if anyone has a load data for them and the 7.62x40wt. Figured they would be good plinking ammo. http://www.midwayusa.com/product/584609/sierra-pro-hunter-bullets-30-caliber-308-diameter-110-grain-round-nose-box-of-100 |

i have shot the 30 carbine 110 fmj's and they work good for plinking i think you need to run them slower but haven't tried that yet. i think if they were backed down to 2200 fps or so they would probably shoot better. somewhere around 24 grains of 1680 would be close.
here is my load to oal and bullet data 
here is a link to a post with 30 carbine bullet targets if you would like my chrono work up data pm your email and i can mail you the excel file. here is my chrono data 110 30 carbine fmj ladder and off land test all the loads are .020 off lands 25.8 1680 110 fmj .020 off lands 1)2422 2)2441 3)2391 4)2451 High:2451 Low:2391 E.S.:60 Ave.:2426.3 S.D.:22.9 26 1680 110 fmj .020 off lands 1)2449 2)2421 3)2465 High:2465 Low:2421 E.S.:44 Ave.:2445 S.D.:18.2 26.2 1680 110 fmj .020 off lands 1)2460 2)2495 3)2451 High:2495 Low:2451 E.S.:44 Ave.:2468.7 S.D.:19 all thes loads are .010 off lands 25.6 1680 110 fmj .010 off lands 1)2408 2)2416 3)2389 High:2416 Low:2389 E.S.:27 Ave.:2404.3 S.D.:11.3 25.8 1680 110 fmj .010 off lands 1)2416 2)2394 3)2402 High:2416 Low:2394 E.S.:22 Ave.:2404 S.D.:9.1 26 1680 110 fmj .010 off lands 1)2468 High:2468 Low:2468 E.S.:0 Ave.:2468 S.D.:0 26.2 1680 110 fmj .010 off lands 1)2431 High:2431 Low:2431 E.S.:0 Ave.:2431 S.D.:0 Originally Posted By Jourdan_D:

Has anyone tried the Hornady 150 grain savage bullet in the x40?

I didn't know there was a special "savage" bullet from Hornady. I do know that the 30. cal Hornady interlock flat base canelure is slightly too far back ( ie...too long COL) for reliable feeding in a "true" .300sav magazine and my .30hrt (41mm case), but about right for a 38mm cased wildcat I have.......so cannelure would likely be in the wrong place for the 7.62x40, which was designed around 125gr sized standard construction bullets and lighter.

I went out today to shoot the x40 and my newer 6x45 and got some decent results. I did blow some primers but, I think my rounds were seated too long and pressure spiked in the chamber. I have to say I shot some 155 grain Nosler Custom Competition over W296 and the accuracy was fantastic, however, the cycling as suspected was lacking due to the mid length system. Has anyone here tried to cut coils off a buffer spring to reduce tension?? This is strictly a wanting to know question since I like running lighter bullets faster and would need the stock spring length anyway.

Have you guys tried any PRI mags to get a longer COAL, and more powder with a little more volume?

IMHO any gains would be miniscule and probably within normal shot to shot variation. if you want more powder/ velocity get a 30hrt.

got to the range again to try the aa2200 with the 125 sierra's
chrono was giving me fits but here is the target. the 28gn load hit 2300fps no signs of pressure yet. don't know how much more powder i can get in the case accuracy is good was only shooting 2 and 3 round groups cause i was mainly checking for pressure. 
and here is my tried and true fire forming load 25.9 grains 1680 with 110 hornady sp at 2425 fps this was rapid fire from bipod. shooting as fast as i could re aim. 1 shot every 1 second or so.
