Only handgun I own that I haven't shot is a Romanian Tokarev, need to get some ammo loaded for it first.
A number of milsurp rifles, most I just haven't got around to yet. M96 swedish in 6.5x55mm, Brazilian 1908 in 7x57mm, 2x Argentine M1909 in 7.65x53 one Cavalry Carbine and one rifle, and a FN-49 in 7.92x57mm. Have ammo loaded for all of them now, just need to get back into routine of weekly range visits to practice with service rifle and take one other rifle to shoot.
I've got a HRA service grade special M1, an IHC service grade and a Winchester service grade that I haven't fired yet, all my Garand firing is either vintage military matches of practicing with the HRA service grade I shoot in matches. M1 carbine that I bought on the forum here that is in line for my next range session, hopefully this tuesday or wednesday. Finally a M1917 Eddystone that I've been unable to remove the stock to cleanup 90+ years of cosmoline due to a stripped and frozen screw. I did get the upper handguard off, then family 'helped' me clean my garage and I've never found the handguard since.
