[QUOTE="Nitroused383, post: 353926, member: 21332"] My load data for 7828sc, WIN 270 Brass, CCI 250 primer, 115 Berger VLD seated .040" from lands. Use caution as these may not be safe loads in your rifle. 25-06 AI, 26" Shilen 1-10 twist barrel. 58g = 3230-3260 FPS 59g= 3375 59.5g= 3418-3454 60g= 3454-3481 60 Degree day 60.2g= 3392-3427 45-50 Degree day 60g = 3463-3499 Hot load sticky bolt lift 75 Degree day All same except CCI BR2 primer and seated @ rifling 60g= 3454-3463 Group sizes and verticle spread shrunk in half. Still no where near as accurate as IMR-4831. The guy on reloaders nest is either insane or his chronograph is broken. I believe he is using nickle plated brass. As you can see 7828 spikes pressure very quickly and you need to be very careful. Gaining rougly 100 fps with 1 extra grain of powder [/QUOTE]
