I actually have a few milsurps, couple of nagants, enfields, turkish mauser, arisaka and an old veterli/vitale that I will probably never get to shoot. I just plink with them though. I've never developed a load or seriously shot target with them.
I collected a couple of milsurps. I like the history behind them and I would look for a bayonet for it and shoot it a little.
I like them because most are relatively inexpensive and ammo ,well, used to be readily available.
