Ed. Nice M70. Specs?
I recall Rich at Sierra using H335 over their 225's....
Ron - I'd say your XTP would do fine at the 357 rifle speeds aka 2k. At 3k they would be a bomb on broadside lung shots.
My feelings are this round dotes on 225's for big game - better BC than 200's and likely penetration. Better trajectory than 250's.
If not mentioned:
http://www.leverguns.com/articles/paco/358_wcf.htm i don't even have the rifle yet, but so far two orders from midway.
last night it was a lee 200grain mold, gas checks and one of those push sizers dies.
I am going to powder coat them after putting on gas checks.
