I'm mostly a mauser guy, but today something caught my eye. I was scanning the local classifieds and saw an ad for a Gras in .22. It's marked m80 and appears to be a full size gras, but the seller is stating it's a .22. The stock has been cut down at the barrel band and I guess there's something up with the front sight but other than that it appears to be in good condition. My questions before purchasing are what variety of .22 can I shoot in this thing? I have a ton of LR's but he's stating that it's in .22 long, which is the first chambering of this I've heard for a military trainer. Additionally, am I okay to shoot modern, bulk pack .22 in this? Where it's marked 1883 this is before smokeless, but then again it's a .22 in a full sized rifle receiver so maybe there's an exception. Let me know. Thank you all in advance!
