Hi All,
Several years ago I loaded up a fair few Shot Loads, using .357 cases for extra length, I put a moderate charge of red dot powder, than seated a thick (0.060 or so) plastic wad, cut from an ice cream container lid using an old re-sized 38 case as a wad punch of sorts.
then fill the case with as much no.9 shot as would fit, then another card over the top, then a really heavy crimp, and I mean really heavy, the case mouth was crimped in as far as I could get it, without the heavy crimp, unburnt powder etc was the result, heavy crimp was good.
Shot at 7-8 yards, into a heavy piece of 1/2" builders ply that was 12" x 12", there was not a area any bigger than a 3/4" dia coin that didn't have a pellet in it, the pellets were going in to the board well over half way through.
I never got to hit a snake with one, but I have no doubt any snake would be toast if hit with one of these.
I was using my 6" 686 at the time and point of impact was perfect for my 125Gr hot hot HP load.
I now live well out of town in brown snake country, so a few more may have to be built before summer comes again.
PS: forgot to add, the recoil was simillar to a WW 125gr factory .38 spec load, not a +p, just the regular lead load.
