[QUOTE="backwoods83, post: 1004300, member: 29890"] Once you find the sweet spot, the 3 or 4 closest shots, 1.2-1.6grns, there will be almost no vertical dispersion usually less than 3/4" for 3 shots or under an inch for 4 shots. If you are using winchester or remington brass start at 64grns with Imr7828 ssc and work up to 68.4-68.8grns. Yes that is over listed max but 7mm rem mag data is very anemic, 61k psi vs 64-65k psi of every other belted magnum which has 375 H&H roots. [/QUOTE]
