What gun and what barrel length are you using? Some Buffalo Bore ammo isn't safe in all guns, so just be sure.
I always go with the heaviest hardcast bullet available if I'm just looking for penetration.

thanks for the replies guys, i carry a 4 inch taurus model m616 i carry it because its so light, buffalo bore says on thier web site that the 357 mag ammo is safe in all guns in working order, and will affect your gun no differently than other ammo, they do say that there is possible crimp jump issues in lighter alloy guns but the ammo its self is safe. with the porting on this gun recoil isnt that much different than any other 357 ive shot, plus taurus's web sight recomends max of 158 grain with something like1450 fps.
The buffalo bore 180 are heavier but have less velocicty than taurus's recomendations and im not going to be shooting these unless i really need to so i think they will be just fine,
and no i do not plan on shooting a bear with a 357 but if the situation arises i would like to have a pierce of mind.
