[QUOTE="BountyHunter, post: 24236, member: 12"] Think he is talking about the variations of the 250 case the highpower shooters are using along those lines. You can go to long range target shooting.com and read the threads. However, they only build guns and chambers to high power accuracy levels of .5 moa. For example almost non are tight neck and cases are not neck turned etc. Most LR BR 1000 yd guns are down in the .1-.3 moa minimum. Just a rule of thumb I have used, take the average group at 100 say .2 multiple by 10 (2 inches)and double which would be about 4 inches at 1000. Now that leaves not fudge for wind and operator headspacing. But if you look at what most LR guns do at 100 and then compare to 1000. That will put you pretty close. [/QUOTE]
