Reloader15.
I've used just about everything else over the last 40yrs, starting with IMR3031, IMR4198, and IMR4320 back in the late '60's.
I like BLC2 (duplicates Winchester factory 150's at 35.7gr) but can be loaded up to 37.5gr with 150gr bullets.
Also H4895, at 33.0gr, some lot's with 34.0gr with 150's.
But, neither will give velocity WITH peak accuracy like RL15 does with 150 and 170gr bullets.
I've found that 36.0gr of RL15 is superlative with the 125gr Sierra FNHP, and 37.5gr with the 130gr Speer FN. (yes, these are correct, the Sierra has most of the bullet below the cannulure, the Speer above the cannulure.... The Sierra can't be seated over more powder in the cases I used...)
H322 has given superlative accuracy, and H414 has application with the 170's but velocity is about 100-150fps below RL15 potential.
Didn't like H335 or RL7.
