Misc Question about 12 G to 45-70 insert
I bought a couple short sub caliber inserts for my coach gun, some rifled and some smooth bore.
One in particular is a 45-70 smooth bore insert with like an inch or less of actual bore. I know these are meant to be safe but has anybody used them before? It’ll be in a 12 gauge coach with a 12” barrel.
My main concern is, is this round going to tumble wildly striking the barrel before it can escape the muzzle?

Yeah that’s the advantage over long inserts. I have no purpose in it other than a dorky thing I find fun to do … “tasting” every caliber lol .. I’ll try 45-70 eventually once I run out of other things on my list lol
