Re: 7mm Bullets with high BC
Try JLK 168 and 180 both with BC of .690 and .738. Both will work best with 9 twist. The 8 twist will not work well with them at least at 7 Rem Mag velocities.
OK Weber sells them and has website.
sierra just came out with a new 7mm 175 grain. Dave Tooley has been testing it for them in 1000 yard and doing very well. Not sure what published BC is.
7WSM just set new NBRSA record and shot a 10" group at 1 mile in Iowa last fall in 1k competitions.
