I have several C&Rs that could be considered rare or expensive and I do shoot them, but within reason. One reason I own them is I enjoy seeing smiles on peoples faces when they get to hold and shoot a piece of history. I have a 1873 Custer era Carbine that does see range time, but only with black powder, reduced loads, my Lend Lease Garand goes to the range every so often, but then I have another Garand to pick up the slack. I have a 1913 NRA Sales M1903 that I have yet to take out, but it will go out sometime, for some reason US bolt action rifles, other than the Krag, really don't excite me.
The only answer that matters is the one you decide on. For myself, the enjoyment of sharing some historic arms and introducing people to shooting is all I need.
