I spoke to a rep with Hevi-shot today and after a 5 min disertation on gun care and storage I was told that these loads were within SAMMI limits. They also stated that any gun that I would shot regular trap loads in would have no problem with there shells. I then asked since you publish the velocity at 1250 pfs you should also know the pressure value. I was promptly told that they do not publish pressure values. Since I am careful what loads I shoot anyways I don't guess I'll be buying any for my 100 yr old Parker.
