That's a really cool setup.
I've got some old boards that I lay in the yard on three sides with a stump at the back and put as many jugs as I need in the trough. It works, but I've no doubt that setup you've got would be handier.
So do you have any results yet?
I'm waiting to amass enough jugs to test the factory 125 gr 38 special +p Rem SJHP against some handloads I put together with the 135 gr GoldDot short barrel bullets in 38 cases.
