Ny basic inquiry would be, WHY would anyone want a 1-8 1/2 twist in a 7mag?? that would seem to be for use with a 175 gr or so bullet. Might stabilize lighter ones, but why go for the long heavy bullets when not needed on Sheep. Also, though could just be personal preference, why a 7Mag? why not a 280 Rem or O'Connor's 270. He killed a number of sheep with that round. Warren Page used an (essentially) 7mmRem mag, and one load, with the 175gr bullet. But he was an experienced hunter, so using a perhaps slightly overweight bullet not a big disadvantage (Warren killed over 400 head of game with his rifle, so knew it well). Seems to me some people start looking at a project, and then don't get all the information they need on what will be needed. Like Dwayne noted, a whole lot of sheep shot under 100 yds. So why not a 280 or 06?
Brain Leitz dominated his first F-TR match with a 9 twist 308 win
