Both of these groups were shot at 100 yards with Federal Gold Medal Match ammo. The one in the center measured 1.75" and was shot with the 175gr GMM and the one in the top right measured .43" and was shot with the 168gr. Both were shot consecutively. The 1.75" group is a fair representation of all of my 3rd groups of this ammo which measured between 1.85-1.15. The average size of the 168gr was .55". All were measured center to center. My question is... Is that normal? I don't understand why 8gr of weight would make such a big difference. They were shot with a remington 700p using the standard 26" 1 in 12" twist barrel. The barrel was broken in properly. Any insight would be much appreciated! p.s. I also shot some 150gr Hornaday V-max and my average 3round groups with that measured .75"
