300BlkTalk

I bought the sparrow, essence and Spectre. I love them all.

Spectre has to be the best bang for the buck though.

I use extended rails. Seekins and the new aero precision MLOK.

I don't shoot full auto but heat isn't an issue for me.

My saker 5.56 gets released next month so maybe that will change things. 300BlK only right now.

Anytime lead is aqueous (dissolved) you should run away. Latex gloves aren't enough to protect you from going Vincent Van Gogh.

Thanks. I posted it there. Feel free to lock.

When casting molds what grain size / speed need a gas check? Does powder coating allow you to push the bullets harder while keeping plain base? What about smooth vs lube grooves?

What length and grain size should I go with?

Rob Silvers says 300 BLK is best in the 100*-130 grain range. That's fine for super sonic. I'll get one at 120 grains. But what's the best grain size for subsonic?

try to PC some of the lighter boolits though.

Do you suppress? How is the can?

I'm thinking about this Lee TL 309-230-5R mold. Plenty of options. What do you recommend? This will be subsonic suppressed only which makes me think powder coat option / size will be best? http://castboolits.gunloads.com/showthread.php?234526-A-C-E-300-BLK-subsonic-boolit 6 cav only PB and GC and op...

Thank you so much! Buying that stuff now. Also, looks like the 240 grain was your best performer at 0.769" 3-group. Got a link to that mold? I can't find it anywhere. Review link: Lee 240gr with Gas check 1.143 group Best 3 - .769 Lee 235gr Without gas check 1.594 group Best 3 - .987 NOE 241gr ...
