Re: .338 Lapua Loads
I tried quite a few loads in my lightweight 26" barrel lapua last week. With a 225 AB the three best groups were 100 grains of 7828 at 3316 fps, 103 grains of magpro at 3304 fps, and 104 grains of re25 at 3310 fps. All of these loads had less than 15 fps spreads.
With the 250 grain the best loads all hit right around 3100 fps. The best was a 5 shot group of 99.5 grains of magpro. 3098, 3101, 3099, 3101 and 3099 fps. I didn't measure the group but it was under two inches at a quarter mile. I have found magpro to give very consistent velocities. In my 338 ultramag right after this group with a 225 ab and 97.5 grains of magpro it shot 3229, 3231, 3231, 3228 and 3229. Same group under two inches at a quarter mile.
Predictions are difficult, especially when they involve the future
