[QUOTE="Huntnful, post: 2250690, member: 116563"] I've been reloading for my 28 nosler for a little under a year now. But loaded about 300 rounds, doing various load development for several bullets with great results. I've strictly used N570 with ADG and Peterson brass and 215M's. All of my loads now are consistently taking more than average amounts of powder to reach previous pressures and standard velocities. But it didn't initially need that much powder from my early data. Who's got ideas? Also, loads that I loaded up way in the beginning and verified velocity, now shoot at a considerably lower velocity. Like 100 FPS slower. FYI gun is custom built and throated for 195's to seat with the boat tail at the edge of the case neck. Examples. OLD LOADS 195 Berger. 81.5 gr. N570 3030 FPS 169 Hammer Hunter 84 gr. N570 3300 FPS NEW LOADS 195 Berger 84gr. N570 3030 FPS 169 Hammer Hunter 88gr. N570 3300 FPS 180 Berger Hybrid 87.5 gr. N570 3185 FPS Pressure signs are velocities are the equivalent as prior, just takes way more powder. I do everything safely and work my loads up slowly, but I'm genuinely curious on what gives? Thank you for your input and advice. [/QUOTE]
