[QUOTE="Lefty7mmstw, post: 777456, member: 48043"] 78 grains 7828 with the 140 sierra was my standard load for quite a few years until rl25 came along. I switched because rl25 gave me the same basic speed (3350 fps- vs 3375 fps for 7828) with significantly less pressure peak and a bit better uniformity. It is also just as capable accuracy wise; both handloads were 1/2 moa average. Some of the peak pressure spread on the handloads was likely mixed trim lengths. I was using borrowed equipment at the time so I was more concerned with getting the ammo loaded than it being perfect. As long as the brass was usable and the charges/ bullet seating were correct it went home. Part of the reason I asked my brother in law to help put a gauge on my rifle was the fact that there was NO data for rl25 at the time as it was a new introduction. I was very concerned that I was getting the charge weight to correct levels. [/QUOTE]
