Where did you guys acquire your sauvestre rounds from? are they stocked locally?
I'm probably going to expand my test somewhat, and go ahead and build some sections of interior wall, some car door sectioons, and possibly some automobile glass.
I'll see if i can find around 30 rounds of each of several kinds of popular smoothbore slug ammunition, like remington, brenneke,winchester,sauvestre,etc. and test them for accuracy, reliability abd perforation of barriers.
After looking at the brenneke website, I noticed that they make a reduced recoil slug load. I'm thinking that's the hot slug setup.
I'll have to shoot it in my guin to see how well it groups.
