based on what you've already got, I'd suggest .300BLK. it's a tinkerer's/reloader's dream. Factory ammo availability is as good or better than Grendel, and no more expensive. You can use nearly any .30 spitzer bullet ever made, converting brass from .223/5.56 is pretty straightforward, brass lasts forever, and it's not powder thirsty at all. I do some bullet casting, and the blackout is ideal for plain lead...even in an 8"twist. with a 110 gn load, you can get 2300+fps from a 16"barrel. Short barrels don't lose much velocity if you'd rather do an sbr. You can duplicate 7.62x39 ballistics with a 125, or slow it down suppressed with 250 grain thumpers without even monkeying with your gas system or buffer.
It's the most versatile, cheapest to shoot cartridge that I reload for.
my favorite current load is a powder coated 230 grain boat tail spitzer bullet from the Lee .309-230-5r mold over 7.3-7.4 grains of lilgun.
size to .309 after coating, and seat to the crimp groove. The most expensive part is the primer! these are pretty darn quiet from a 16" barrel at 1100fps, even unsuppressed.
with a can on, you hear the hammer drop and the impact on target. With the insane BC of that bullet (.688 G1), it retains good energy WAY TF out there.
