I've owned a lot of un-modified military rifles over the years, but don't have any at the present time.
Mausers, GEW-88 and 98, Type 99 and 38 Japanese Arisakas, Russian Mosin Nagants, SKS rifles, M1-carbines, British Lee-Enfields and SMLE and scads of small pistols. Unfortunately I usually sold them or traded them for something else.
The two I shoot the most when I'm working up handloads these days are a 1942 Lee-Enfield British .303 lend lease made by Savage Arms, and a 1918 Springfield M1903 with a 6-24x42 scope that I use working up 30-06 loads. Both have had the forearms cut off.
I found the Lee-Enfield at a garage sale about 10 years ago. I asked the guy if he had any guns and he said he had an old rifle in the shed that he'd take $10 for. The rifle was covered in crud, oil, and sawdust. I had to use a rubber mallet to free up the bolt. Once I got it cleaned up and put a "no-drill" scope mount and a scope on it, it shot pretty tight groups at 100 yards. Even so, it looks pretty bad with thick surface rust all down the outside of the barrel.
The hell of it is, the guy that sold it to me tried to kill his wife with an aluminum baseball bat two weeks later. He beat the living crap out of her, but thankfully she survived. After beating her, he put a shotgun to his head.
I just keep the rifle because I got it so cheap and it shoots well. I make handloads for it by fire-forming 30-40 Krag cases and trimming them down a little.
