I never owned a semi auto centerfire, YET!
Although, I did own a Amish Machine Gun for a few years. I think it was my 2nd CF rifle. 1st was a Savage 110 then I got the Remington 760 .308Win in a LH configuration. (just the stock & safety were LH, factory issue)
As far as semi auto shotguns, I never owned one until I was an old man. 38 yrs old. <grin> I got the Benelli SBE in '99 and then the 20ga Montefeltro a year later. Why did I wait so long?
I've put thousands of rounds down the tube on the 870's and 37's and killed toooooo many deer with them but they don't get much action anymore. Both of those models are bullet proof.........
Carry on fellas!!
