went to the range today with my .22-250 and did better than expected. ive got a cheap Bushnell Deer Hunter 3-9x50 on it.
winchester cases once fired, 55 grain sierra spitzers over 34 grains of IMR 3031 with CCI primers. full length sized because i dont have a neck sizing die yet. one inch five shot groups, with one five shot group at .840. i thought that was pretty good, seeing as how it was windy and my brother was shooting his romak right next to me, pelting me with steel cases. i tried a few rounds that i had factory crimped and i didnt care for the results, but i expected those to suck anyway.
one thing i noticed is that the groups start to open up BIG TIME as the gun gets dirty. i honestly think that the groups climbed from one inch to three from dirt alone. a little bit of cleaning, and they dropped again. of course, i suppose that could be heat too. i suspect dirt though. you might be able to pop prarie rats all day long, but it wouldnt hurt to run a rod down the bore after every twenty to thirty rounds.
