I have a Kibler SMR .45 cal with walnut stock. Barrel and iron hardware are Jax-blacked. Thinking about ordering another SMR as a winter project. Probably maple-stocked for a change, and browned barrel and hardware. Undecided whether to get another .45 cal or to go with .36 cal for something different. I do like .45 cal and mine shoots great. Goals are mainly just the project with an end result of just target shooting and not hunting. Opinions on whether to go .36 cal or .45 cal?
