H1000 and the .243??

[Rifleman513]

I've been running Retumbo and 105 AMax's in my 243. The load data is on Hodgdons site but I believe I'm using 48.5 gr. I get about 2900 from a 22 in barrel. It is a packed full case but the accuracy is impressive. Also its nice I can use the same powder in the 243 and my 300 RUM.

RL 26 is awesome in the 243 with heavier bullets.

Pushing 105 amax 3100 with 47 grains.
