I took my 264Win Mag to the range and for the most part I was very impressed. I was not at all impressed with the factory Remington 140gr Core Lokt factory ammo. The best I could get was 1.943" @ 100yds from 3 shot groups. This morning I reloaded some 140gr A-Max. I measured the coal with a projectile on the lans and got a total length of 3.306". I loaded 3 rds each with 61, 61.5, and 62gs of H4831sc seated at 3.304". The 62gr load cronyed @ 2930 fps at the muzzel.61gr grouped @ .401, 61.5gr grouped @ .444, and 62gr grouped @ .485. This is with a stock Model 700. The trigger is less than ideal but all in all I was satisfied
