Never tried it in a regular .357 barrel, but i shoot 180's & 200 grainers in my 10" .357 Max & my 10" .357 Bain & Davis quite a bit. Seems to shoot 'em fine, no evidence of higher chamber pressure in using .358 diameter instead of .357, as long as you stay within recommended powder charges for that weight of bullet. I also liked the 150 grain Remington .358 SP's back when they were easier to find.
