I moved from a .223 LRPV 9 twist to a Savage .223 F/TR 7 twist to shoot heavier bullets at longer ranges. IT DOESN'T. In fact, it shoots 69 gr bullets better than anything heavier. I sent it back to Savage and got it back with a ".7 target" with a flier which made it more like a barely moa test from their indoor 100 yrd range.

My question is this: how can a 100 yrd indoor test range with a 69gn bullet be a valid test for a gun that is made to shoot 200-600 yds with bullets that range from 69 (at the low end) to 85 gn?

I called them and they said the 100yd is all we have.

If a gun shoots ok at a 100 with a light bullet does that mean it should shoot as well at 200-600?
