It's according to what loads you're using...S&B loads are hot compared to Winchester USA or UMC loads. Most of the american loads are lowered so they don't destroy the lower quality guns like Jennings/Bryco/Davis/Raven/etc. Most of the time european loads are hotter than ours...Fiochi is hotter to. Chinese 9mm ball was even battering the lower quality guns up because it is loaded to NATO specs.
