After shooting a fully loaded 8 bore, you, Ben, will NEVER want to shoot a 4, please trust me on this. Perhaps a 20 year old's retinas might remain attached, but maybe not yours. How much is your sight worth? A well loaded 8 bore will be found to possess more than enough recoil to make you think you've shot a BIG bore gun, I am sure.\
; A friend has a nice 5 bore, ball and shot gun, muzzleloading, that he has used at local trap shoots. With only 3 ounces of shot and enough of a charge to get about 1,000fps, it absolutely smokes the birds from the 16 yard line. The gun's 12 pound weight is a bit cumbersome for trap, but allow one to get on the bird before the cloud of shot has depelted itself. He has stated he'd never shoot a 4 bore as his 5 is big enough. It was a 6 bore until re-furbished by Holland and Holland.
