Does anyone have any experience with Magpro powder from Accurate Arms? I know it was developed for the short mags, but looking in the manual this powder is attaining some high velocities in standard calibers. If anyone has used this powder please give me some insight as to the results you have gotten. I would like to try some in my 280 Rem. behind a 140 gr. Nosler Bt.
