Thread: 300blk Loading Tips

H110 I found really only likes fast supersonic loads with light bullets in the 110-120g range. I found it very inconsistent with heavier bullets and it's a powder that like in 357 Magnum, it likes to be loaded near max to work well.

Lil Gun works well in the mid range it seems. I use it a lot for 150g bullets.

CFE BLK goes well with heavier bullets and is probably ideal for subsonics.

I'm doing a lot of 300 Blackout stuff on my Youtube channel so feel free to check it out. Same user name. Right now in the middle of doing a series on 150g Hornady FMJs. Coming up I have a variety of bullets I'll be working with and doing video series on for 300 Blackout. Right now no plans for subsonics but open to doing videos on it if there is a demand for it.
