I've been reading this thread with great interest. I'm old enough to remember buying milsurps for less than $10 ea at different outlets back when all you needed to buy a rifle was the money! I bought lots and shot the hell out of them, with all manner of ammunition. Most were in their original chamberings but a few were conversions. Never had one that didn't do what it was designed to do.......shoot! Back on point, I have one of these as well. Haven't shot it yet, but I surely will. I was in the loading room just now and made up some dummy rounds to verify some of the comments here.
Here's what I found out about my particular rifle. Chamber is sleeved, and the barrel is 19.25". So, carbine length. No marks to speak of on the wood and the metal is very nice as well. There was some minor pitting caused by poor storage but some transmission fluid and elbow grease got rid of almost all of that.
Now, for the interesting part. I had 4 different .30 cal. cast boolits sized at .3095" Here are the four dummy rounds.
Sorry about the lack of focus, the camera focused on the other stuff on the bench.
From left to right: #311334 sized at .3095" and measured .3000" just ahead of the driving bands.
Next is a 311041 sized at .3095" and measured .2905" just ahead of the bands. The smallest of the four.
Next is a 311413, sized at .3095" and measured .2995" ahead of the bands.
Lastly is number unknown, sized at .3095" and measured .3065" ahead of the bands, the largest of the four. I loaded them in the magazine and cycled the action and all four chambered with no issue other than the last round hit the top of the chamber before chambering. So, four different boolits all sized at .3095" and different groove diameters and all chambered with zero problems.
