I am looking at loading lead bullet for subsonic. I have found the Missouri Bullet Company offers a 240 gr lead bullet. I was wondering if anyone has loaded them and how did they do. I would possibly use this bullet for Hog Hunting or deer. I have H110 and Lil Gun on hand.
If anyone has any other suggestions on bullets let me know. Thanks MAHA |

Thanks MAHA look at my link on the last page to subsonic hunting. the NOE cast bullet I used is pretty much the same bullet as the MBC 240. While it can work. It IS NOT optimal as it is at subsonic velocities for hunting purposes. |

You can do a 150gn sub. But it isn't gonna have any ass on it. If I were to use a 150 for subs, it would be for very close situations. Like under 50yds. max.. Of course garyd may have something else to say about that as he has a ton more experience with subs.
ETA: I thought about doing the same with these 165gn Nosler Accubonds I have on hand. At 1065fps. they would have 414lbs. of energy, so I don't guess it would be to bad. 150's have around 400lbs. at the same speed. But keep in mind that due to weight they won't carry that energy very far. |

Is there a gas check needed if used with a suppressor? yes it will feed. there have been a few who have had problems. usually adjusting the OAL fix it. I have shot a lot of them. no gas check at sub velocities needed. but I would not recommend shooting thru a sealed can. you will get lead splatter on the first baffle depending on design. I powder coat now and no leading at all. |

MAHA Short answer AR15 no Single shot or bolt action, yes. Long answer. Some guys have claimed to have gotten 150gr subs to cycle the AR15. others have tried with no cycling of the action happening. I have tried it and it was not worth the headache so I did not pursue it an further. I have gotten the 178gr amax to cycle an Ar15 with out the can. But only with 1680 powder. I think for practical purposes 200 is a good minimum weight for subs. Although the Lehigh defense 174 gr controlled fracturing is supposed to function an AR with the correct powder. For a bolt action or single shot, any .30 caliber bullet can be made to shoot subsonic. the advantage being that you can use faster burning powders that are much quieter when suppressed. my 2 favorite squirrel loads are 100gr .32 Hornady XTP and 120gr cast hollow point, both with some trail boss. |

I knew you'd know what to say! I didn't even think about there not being enough PSI to cycle the action. Makes a lot of since. Do you have any experience with the 208gn A-Max? I worked up a subsonic load today with them @ 1060fps. that hit that AR500 plate at 100yds every shot with an Aimpoint. I shot a jug of hot water, and the bullet disintegrated into a bunch of frags. This was at the 1060fps. @ 100yds.. I might mix up a batch of gelatin to find out the real story in the next few days. I'm pretty impressed with this bullet thus far. Accuracy is outstanding. ETA: I'm using A5744 for these, and it's a pretty impressive powder. Real clean, and meters really well out of the Chargemaster. |

I have used the hornady 208gr match open tip. tried some different powders,including 5744. I think it is a pretty good substitute for 1680,since I can't find any locally  . the 208gr open tip was very accurate. I actually picked up some 208gr amax the other day, but have not loaded any yet. It is one of the most popular bullets for the 300blk subsonics. It won't fragment reliably at sub velocities. I forget, but off the top of my head, I believe it needs to be somewhere around 2000fps to fragment.
There have been some guys using it for hunting. As I have stated before. hunting with non expanding bullets can be done, and ethically, one has to be very very precise, and the bullet may not tumble, depending on a lot of factors. |

At 10.1gn of A5744 Quickload shows 33096psi, and at the same 10.1gn of A1680 it shows 21003psi.. I know Quickload isn't real good at chamber pressure prediction. But with over 10000psi. predicted difference, I'm not so sure 5744 is a good sub. for 1680.
Seems it would take a shit ton more 1680 to get the same result of 5744. I'm sure the minimum expansion velocity for the A-Max is pretty high. Which is why I was shocked to see the one I shot in the jug today in a 1000 pieces. I was even more shocked the water stopped it. |

That is odd. But honestly I don't have any experience with Quickload. I know that Accurate Powder lists 5744 and 1680 as their 2 powders for subsonic in the 300 blk. Their pressure listings do have 5744 as having a higher chamber pressure, but the difference is more around 5000 psi, but not necessarily with the exact same powder charge weight. so not sure how much that would effect things. |

I couldn't find any 1680 locally. I picked up some 4227. I am still working on getting my load where I want it, but so far I have had decent results. The last loads I shot were 10.2gr 4227 with 208gr Hornady Match HPBT. The ended up averaging just over 1100fps. I have a few more that I may chronograph today and see were the speed ends up. I am aiming for around 1015fps since that is what my reticle is set up for. |

I am aiming for around 1015fps since that is what my reticle is set up for. IMR, and H4227 are both real close to 5744 in terms of chamber pressure according to Quickload, and with my experience with 4227 it seems they are much more accurate also. More than 1680 anyway, IMO! But yet again, 4227 isn't even close to 1680. IMO, 1680 is much dirtier than either 4227, or 5744, and it requires a compressed load to get good results. I'm not saying 1680 isn't a good powder. I know it is. I use it for 6.8 match loads. But for 300blk I don't think it's worth using in the end. According to Quickload 8.9gn of 4227(IMR, or Hodgdon) will get you around your 1015fps. mark with a COAL of 2.250", and 20299psi chamber pressure. But take that for what it is, cause I've noticed Quickload doesn't play well with subsonic loads. It always gives a much higher velocity for some reason. |

First none of the loads would cycle my carbine, but 1680 loads will. Second I started getting pressure signs that I have never had with 1680. I decided that all my 4227 will be for supers. |

I got to shoot a little this afternoon. Here is what i came up with on my subsonics:
208gr Hornady Match HPBT 2.250" OAL 8.8gr 4227 1020fps average This was shot out of a 1/8 twist 16" barrel with a carbine length gas system. The gas port is opened up to .125". It shot these loads just fine, but would not chamber a second round on its' own. Basically I had a single shot AR. Those suckers sure were quiet with my can though, I am working up some subs for my 308 next and may use the 4227 up on that and find a powder that will make my blackout cycle right with subs. |

Nice, so Quickload was pretty much spot on for your situation. Just not enough pressure to cycle the carbine gas system. |

All you .300 guys posting in this thread - I know you're sitting on a treasure trove of reloading data. Please help fill in the reloading database for this caliber. Please read the bottom of the announcement at the top of the forum on how to format the data to help me out:
http://www.ar15.com/forums/t_6_42/418177_Reloading_database_for_rifle_and_pistol__user_contributed__updated_2_24_2014.html It may take a little time to format and send to me, but this is a community effort. YOU make this place useful; don't rely only on others. .300AAC is one area that I KNOW a lot of people have data for, so let's have 'em. Same thing for other common calibers. Take a look at the data and help fill it in. |

having a brass conversion sizing issue:

To be honest, I'm not worried about brass longevity (I'll lose it before it gets to the end of its life for all my plinking/training ammo) so I generally cam-over with any Lee sizing dies to set the shoulder back the maximum amount for autoloaders - I never bother setting to an exact headspace to fit a guage. For reference, my 5.56 training ammo is .5MOA at 100 yards, 2890fps for a 55gr bullet from my 14.5" barrel so this is not an inaccurate method, but it does work the brass harder.
I had some issues with an oddball caliber not working on all brass using this method (7.5x55mm Swiss in a K-31) and I ended up getting RCBS dies. Don't get me wrong, I love Lee stuff, but for some things they don't work. I personally have had no trouble with my Lee 300blk dies, but if I had the issues you're describing and camming-over didn't help, I'd get another brand of dies and try that. |

I ran into a bunch of brass like that.
Had a bunch of people tell me it was the Lee dies. I trusted my calipers, it was not the Lee dies. Turns out the rims were fucked. It was SAW'd brass. Try to insert the finished brass butt-first into a Sheridan gauge. Factory brass will go in approximately 1/4 inch. The ones with the messed up rims (converted LC with a rough past) will barely go in at all. The rim was holding it up from going into the Sheridan the normal way as well. Using a buldge buster fixed the majority of the messed up rims. Now, if I could get a little Trail Boss the world would be perfect. |

I got a question. I have been forming brass out of .223, first by cutting it with a small pipe cutter then running it through an RCBS small base sizing die and finally trimming to length. When I run it through the sizing dies, I end up with scratches on the neck of the case around the entire circumference. the die did not do
this when I formed maybe the first 50 rounds but it does it now. I have taken the die apart and cleaned it but I can't see anything obviously wrong. I will add that all the brass goes through a tumbling before I size it. Anyone have any insight? Sorry but I have no pictures right now. |

Bottom line: i gave up on converting the pile of brass i was working with. It is GECO headstamp. Found a link on another site regarding this being too thick for reliable conversion.
I converted some LC brass and that was much smoother. I still ended up polishing the sizer down to .306 I would still like the shoulder to be down another .001 or so as the cases are right at the upper limit of the gauge but they are in spec. Btw, i tried the putting in the gauge backwards suggestion to see if they were bulged. no pattern between the unsize/unconverted GECO, unsized LC and sized LC. Between .3 and .4 I also changed my cutoff length to 1.365 versus 1.375. They grow about .005 in length during conversion and thus less material to trim. |

Between .3 and .4 I do butt-first to check the rim, not the case. A perfectly sized and in specification converted case will not fit the Sheridan gauge if the rim gets ripped out of shape from a SAW. Glad you found the cause of the issue you ran into. |

I'm going to buy a power trimmer this week. Probably the one that hooks to a drill press (worlds best trimmer or whatever its called) cause after converting 200 .223 to .300blk my hands were killing me and I had a blister on my palm from the manual RCBS trimmer I'm using.
But I did pick up 2 lbs of W296 from the LGS today as well as some 110gr Nosler Varmageddons and loaded a few up and sent them down range. Brass was mixed headstamp (mainly PMC) and all of the rounds functioned flawlessly with 18.5 gr of W296. Chrono averaged at 2140 after 10 shots. These were the first supersonic rounds I've fired out of a .300 BLK (just finished my pistol last week and have ran some UMC subs through it) and man did i get a big ol' grin on my face when shooting these high powered rounds! One thing I did notice thats more of a gun related issue than a reloading issue is that during ejection, the mouths of the cases get a flat spot on them. Doesnt matter if its sub or supersonic ammo and I'm guessing that the shorter cases of the 300 blk cause it so that the mouth of the spent case hits the deflector flattening it. Nothing the resizing shouldnt fix! I also noticed at the LGS that a box of 20 Nosler branded cartridges with the 110gr varmageddons in them are running around 32 dollars. I cant imagine shooting this caliber without handloading! 
Guess I can post up my data i'm using that work best in my AAC 9" upper. Cases FL sized and trimmed to 1.358" +- .002" Remington 6 1/2 primers 18.5gr W296 ball (best metering powder on the planet!) 110gr Nosler Varmageddons 2.025" +- .002" COAL |

I found a discussion on Reddit recently about converting primed .223 Remington rounds into primed 300 BLK rounds without removing the primer. So I decided to do exactly that.
You don't have to use primed cartridge cases for this method. That was just a proof of concept demonstration. I don't seem to know how to embed the album into this forum, so here is the Imgur Album link: http://imgur.com/a/I6Mgd <iframe class="imgur-album" width="100%" height="550" frameborder="0" src="http://imgur.com/a/I6Mgd/embed"></iframe> [imgur]I6Mgd[/imgur] Here is a video using the WFT to trim to length in one step. It is very loud, please turn down or off your speakers [youtube]http://www.youtube.com/watch?v=rRyu22EMFKY[/youtube] I have no idea why these links aren't populating properly.

You input case capacity(H2O), barrel length, proper bullet length, case trim length, COAL, select your powder, and enter charge weight. Maybe change the temp., and that's about it. ETA: The load data in that post was using a 16" barrel. Not a 10.5". |

I was thinking about getting into 300blk... But I have no interest in loading sub rounds.. What kind of fps can you get if you loaded it super sonic... Is it comparable to 7.62x39? |
