I have a 4" pre model 29 in the shop right now being fitted and retimed with a new cylinder. I bulged the old one, a stupid mistake with a progressive reloader. 18 grains of Unique, as near as I can tell, will ruin a cylinder. Anyway, it is being cur for moon clips. I will use this gun as a carry piece most of the time. I can shoot the 240-250 Keith style bullets reasonably fast if I keep the speed down around 1200 feet per second or less, and 180 grain hollow points are a max load proposition. Either one will do for deer, bear, or two legged varmints. A 180 XTp is a little shy on penetration for a bear or a hog, but I have lived this long without being attacked by a bear. As for hogs, I am a meat hunter, not a trophy hunter, so twelve inches or so of penetration is fine as long as it shreds the lungs.
I plan to put an oversize thumb latch on my gun, and that's about it. I will probably use Lyman Devastaors as a one load does it all for this gun if I can get it to shoot them well. Reminds me, I need to order one of those molds.I want to have plenty on hand when the gun gets out of the shop.
