    300 Blackout Reloading Question

    Almost done with my 300 Blackout build. I have some 30 carbine 110 grain FMJs laying around. Anyone use them for plinkers out of 300 Blackout? If so, any recommendations? Thanks.

    I have never used RN .30 carbine bullets for BO but I remember reading about those who did over at 30blktalk.com.

    That is the place for all things BO. http://www.300blktalk.com/forum/ A few members have set the standards for BO there.

    Forgot to add if you can get them to feed the rest is just fine tuning.

    I don't see a problem getting the fmj to feed just have to figure out the seat depth.

    I load a 32 gr tnt speer hp for my ar's and that took a lot of work to find the sweet spot where they would load cycle and repeat.

    Worked well. Ran 50 rounds of 30 carbine projectiles, and ran flawlessly. Not the best for long range accuracy, but fine as a cheaper plinker!

    What is your group size like? I've got a few (100-ish) 30 cal bullets in that weight range, they have a copper "cup" holding a LRN projectile; thinking they could be fun out of my Mini Draco 7.6239. Not sure if the twist would work, but it might. I had forgotten about those bullets until now, bought them probably 25 years ago in a "batch deal" with a ton of other components.

    Good question. But I am not sure as I hit some steal targets (safely) down range. Now that shooting restrictions have taken affect due to our dry weather, I will try to see what the grouping is like at a local range in the next few weeks. They are worth shooting though.
