I remember Greg's posts. I would think pressure is to blame for barrel failure, and recoil is to blame for frame failure. Especially frame failure right at the standing breech, the apex of the wishbone so to speak.

It seems to me that cheap "dove" loads recoil faster than better ammo of the same shot weight and muzzle velocity, possibly due to the fast-burning powder used. I save promo loads for the BPS, because they won't hurt it and who cares if they do?
