[grey2112]

Hey, guys - just got my AR-15 .300-221 build done. It has a 16" barrel, 1:8 twist.

I'm looking for some good reloading data for some supersonic loads, just to get things running, loosened up, broken in, etc. before I start really tuning it up for supersonic and eventual subsonic stuff.

I have 125 grain Nosler ballistic tips and 147 grain FMJ bullets to use.

I also have a selection of the following powders to use:

2230 (lots)

Unique

748

Reloader 19, 15, 22

4064

Varget

BL(C)-2

Ramshot TAC

Would love to see if any of you all have some good recipes using those bullets and powders.

Thanks!
