Forgot to mention, Hammer bullets are about as accurate as CEB's.
Here's my CEB "bragging group" that I was not quite able to reproduce, although got pretty close. Not a bad group from a JES re-bored .243 Pre-64.
X-Term is my second fav .358 Win powder. I get similar performance, no compression, with RL-7.
TAC was JB's fav in his excellent .358 Win article. TAC may be optimal with heavier bullets, but will require compressed loads.
TAC is slightly slower than X-Term which is slightly slower than RL-7. Faster powders take up less room. IME, case capacity can be an issue in the .358 W.
Nothing wrong with compressed loads, I like to not compress if I don't have to. Just me.
