[QUOTE="Countrykang8, post: 3086408, member: 116590"] I am in a conundrum. The published data Hodgdon data, for Ramshot Magnum, was pretty accurate for the 28 Nosler. 79.8 grains gave me an average speed of 2954 which is only 24 fps less than what's published and my barrel is only 22", but with a suppressor. I am using ADG brass and multiple primers. I tried CCI 34, BR2, Fed 210M, and CCI 250. They all performed within 15 fps of each other. However, my speeds are lethargic and aren't close to the published 7 PRC data. 1. I shot the Hammer 177 gr with 70.4 and 70.7 grains which gave me 2795 and 2819, respectively. 2. Berger 175 EH with 71.5 grains only yielded 2787 fps. 3. Hornady 175 ELDX with 72 grains yielded 2875 Therefore, I am running 120-150 fps less than what's published for the 7 PRC. This is pretty disappointing. I am starting to believe Ramshot Magnum isn't a good match for the 7 PRC's case capacity. Anyone else have a similar or different experience? [/QUOTE]
