I'm not saying not to be careful but just know some of the loads many of us have been shooting have never been pressure tested even though the developer claims they have and there hasnt.been any issues yet.


There’s plenty of cases showing up on FB pages of breech handles being blown out or as Jstocks mentioned, hulls collapsing in the chamber due to excessive pressures driving the hull back before full ignition occurs. I know most load developers use 14K as the top end of the pressure range but it doesn’t take much with these heavy payload shells to exceed that. The guy at Precision Reloading told me these were dangerous, especially in lower end quality guns. It would be totally irresponsible for a load developer to send out info that hasn’t been verified. Be very careful of who you buy shot from and whose recipes you are using!!!!



A lot of truth there

Reloading shotgun shells can go south quickly. The pressure signs are not necessarily like reloading metallic cartridges.

I've been loading steel shot shells for years now and one thing that has been engrained to me has been having to be careful. A few years ago Steel Powder supply dried up and then the new Lots hit the shelves and they were hot. I blended mine with older Lot numbers and reduced th charge. Some guys had some real problems and it was reported. I'd always been told to with each newLot number to start low and work up just to see.

The problem is that the pressure signs sometimes do not show up until it's too late.
