I use the 140 Sierra FBSP in my 7mm Mags (have 3) and the accuracy is superb. The best group so far, 3 shots at .096 and five shots at .198 Velocity was 3133 load is on this site at 66 grains of IMR 4350 with bullet seated .003 off. The load is in the old Lynman book as the accuracy load with this bullet.
After 50+ years of shooting I have found that the flat base is more accurate than the boat tail, as Rocky said in a prior post.
