R-15 works great with 50g bullets in the 22-250 never tried it in the 243 (use varget or IMR 4064) but it should be real close
Not a 223 or 204 shooter so I'm no help there although 10x should be good in both
Does anyone claim any success (or failure) with Reloder 15 (or 12, or 10) in .223 & .22-250 using 50 & 52 grain bullets and in .243 with 70 grain bullets or smaller? I'm running Rem brass with Federal match primers. Bullet choices are Sierra, Nosler, and Combined Technology.
Thanks, Steve
PS- How about .204?

In my Savage Predator in 22-250 it's the only powder I use. I shoot Sierra 55gr Blitz Kings behind 37.1 gr of RL15, CCI BR2's, OAL 2.095 (to ogive) avg. 3725fps in a 22" barrel. Shoots .3 -.5 all day long.
For .223, R-10 would work good, R-12 would be doable and R-15 just burns too slow for such a light bullet in that caliber.....
For .22-250, they would all do pretty good....
27.5 grains Reloader 15 in .223 with a 50 grain bullet.
41 grains Reloader 15 in .243 with a 70 grain bullet.
