I probably would try the .300 Winnie Mag again as the felt recoil probably isn't too much worse than a hot 30.06 cartridge. The 416 that I shot prior to the .300, had a miserable hard butt plate on the stock and the scope was set-up with poor eye relief, in all honesty, I am sure that my shooting form was quite poor back then (in my mid 20's

) and I am lucky that I did not rip my eye out of it's socket. I would also not attempt a benchrest shooting with a larger caliber without the aid of a leadsled.
"Yeeehhhaaawww..I alus wanted to be the son of a rich father!" And here I was getting all excited Skeet, thinking that it was you that was going to be doing all the paying and adopting!
Gosh Darn! I was just thinking how much fun it would be on that offshore rig with some exotic beauties pulling trap for us boat-side when the fishing slowed down! Oh well, I guess I'll have to get back at work!
Wifey is supposed to begin bringing me home the mish-mash of the new reloading collection begiining later in the week.
