I shoot groups like that with milsurps pretty regularly, and have for a couple decades...like I said, it's not that great, I know plenty of guys that shoot better, but that's what gets me out shooting. Not just to make noise, but to actually shoot better every time out, it's a challenge, I like a challenge. I'm married and have a nice wife so I don't need any "stress relief" shooting lol.
About 15 years ago a fellow on here wanted to trade his USGI 1911 for my Breda M1. We met up at the range, did some shooting with each gun, and I was going to put my last 8 rounds though it. I shot a group at 100m that was about an inch, maybe a touch less with those 8 rounds, and that was it... I was far more interested in accurate shooting then I was in spraying bullets everywhere. Actually, spraying bullets is ####ing annoying and frustrating to me, and I've dumped pretty much every inaccurate rifle or pistol I own save for a few. Wish I could enjoy it, but it doesn't interest me at all.
I still have that Breda...and a few other milsurps that shoot like target rifles, K31's, 1917's, AR15's, some mausers. Not a single one of them cost me $1000 either lol.
