[QUOTE="BMF, post: 817896, member: 12201"] If your shooting .5 MOA at 260 and 400 yds then your load sounds somewaht solid. It looks like about a 9in group at 600 so there's something happening here. It might be a form issue. Make sure that you put the same amount of shoulder pressure into your rifle every time. Especially if its a lighter gun. Be consistent here, it makes a big difference. It also may be a velocity issue. Without a chronograph it'll be tough to tell. Actually the more i think about it, it's probably a velocity issue. Past 400 yds is where you start to see loads with a high ES (estimated spread) begin to string shots vertically. First, make sure that your powder scales is consistent and repeatable. You can also play with seating depth a litlle. Maybe try seating 4 loads, ten thousandth deeper into the case. I dont want to say the other way (into the chamber) because i dont know where your at now. It also looks like you got some wiggle room + or - with your powder charge. Sometimes .3 or .5 more or less grains can lower the ES. I don't know what primer your using but it should be a quality one. You can do a search on this forum to decide for yourself which ones are the best. But CCI, Federal, and Winchester seem to be used a lot. Then if you go to the CCI and Federals Benchrest and Match primers, they're even better You can do this without a chronograph, its just a little tougher. But if you plan on doing a lot of long range shooting, it might be worth investing in one. There's a thousand different things to consider when reloading that can shrink group sizes, its mind boggling.....best thing you can do is get on this forum and read, read, read, and become a sponge.
