300 blackout load data

[Egturbo02]

any one have any load data for 300 blk with Lil Gun powder and .308 147gr pull downs?

The best source for j-word loads is probably on 300blktalk.com I have done 16.8gn of Lil Gun under the 147's and they worked well enough in both my AR's.

The 300blk is an easy cast boolit cartridge and a number of us here have worked up combinations that work well. Use the search.

My pet combo is a Lee C312-155-2R boolit with Hornady gas check sized to .310 with Tac#1 lube on top of 17gn of Reloder 7. Custom PTX is used to open the neck to .308 and impart a small flare during case powder charging. Seating and crimping is 2 steps and a Lee FCD is used to give a light crimp in the crimp groove. This combo works well for range work and wild hog hunting.

Start around 16gr and work up. 17 would be about max depending on seat depth.

Thanks guys. I'm going start it at 16gr and fo up from there.

Oh just to some more info if it matters. Its 147gr fmj pull downs from topbrass and its going to be used on an ar15 with 8.5" barrel. Thanks in advance

Would xtreme 150gr flat point full metal jacket bullets work also? If I can use those for just plinking that would be great. What would the load data and coal be on that? and I'll be using lil gun powder. Thanks
