I had an abbreviated day at the range, but a fun one.
I started off shooting a new-to-me Mauser .22-250 that I accidentally bought off GunBroker. I put in what I thought would be a low bid and no one outbid me. It had an old 6-24x scope on it when I got it, but I sold that right away and made a good bit of my money back on it. Then I put on an SWFA 12x I acquired in a trade on Rokslide. She’s got a 24” barrel and weighs 11# in the current configuration. I haven’t measured the twist rate, but my assumption is 1:12.
In the past, I have had respectable results from the Sellier & Bellot 55-grain SP ammunition. It’s also very cheap ($14.22/20). The box velocity is 3478 FPS. I got 3555.8 with a STD Dev of 22.3 (40 rounds total). I recommend this ammo for anyone who doesn’t want to reload their own, but I am confident that I could halve the groups with reloads. Here are a couple of representative groups (corrections made between groups).
PS - I have too many rifles, so this one is going up for sale soon.
