I spent some quality time with a couple of them last week ... a 4" round butted gun, and a 6" field grade, and a whole bunch of Grizzly Ctg. ammunition. Darn it, I forgot the bullet weights, but I think the low-end load was a 370 grain bullet at 950 fps ... also shot a good bit of medium-range loads, and a few of the heaviest.
That low-end load is pretty darned interesting.
I am now giving serious thought to a 4" 500 WE ... boy, that made for a lightweight, serious packin' pistol. Also giving serious thought to a good 83-22 instead, as it seems like all I am doing now is buying box after box of bullets, and casting just ain't in the cards right now.
