Ive been reloading for my M60 3" sixgun for years. It is a perfect concealed carry weapon in the potent 357mag class. But I do not enjoy shooting it at full 357mag power. I adjusted down to what I would call is 38+p loads say 950fp using 158gr slugs. Hornady XTP are good as are Rem SJSPs. 12gr of 2400 or 6.2gr of W-231 get you there with tight accuracy. If you don't have accuracy you have nothing but noise. I use 180s in my Marlin 1894 carbine but that's for big game out to 100 yards. A bit much out of small revolvers.As for snakes just walk around or back up from them on the trail, no need to shoot them. back pack of the usual supplies and your good to go.
