300BlkTalk

I loaded 30 rounds (3 different loads of Shooters World Blackout powder) with 220gr Hornady round nose Interlock and will be headed over to the range on my place around noon. Hopefully the bullets will stabilize and I can shoot suppressed after verifying no bullet tumble.

After more searching the site I have found my answer and my 1/8 twist barrel should be fine. Happy, happy!

I'm new at this 300BLK game but have loaded my own ammo for years. I have an AR pistol with 9" barrel and 1/8 twist. I want to load some 220gr subsonic loads as that is the only heavy bullet that I currently have on hand. Will my barrel stabilize these bullets?

Try to put it out of your mind and just let the days pass. My first NFA purchases were a submachine gun, silencer for it and a .22 silencer. I passed the time by buying a Dillon 550B and loading .45ACP for the sub gun because I knew it would spit 'em out faster than I could load them. 13 months pass...

It wasn't the charging handle that concerned me but the front end of the receiver in the area where it appears that the tabs would/will overlap the receiver. I thought they might prevent the flush mating of the 2 surfaces. I should have been more clear on my concern.

Can anyone tell me if the MI SP series hand guards (suppressor ready) are compatible with BCA side charging upper receivers? These hand guards have an angled 'tab' at the 11 and 1 o'clock positions (looking from breech toward muzzle) that look like they will interfere with the BCA upper.
