6 Dasher with 90 lapua

[RTW]

I need some help with loads for a 6 Dasher. What would be a warmish load with lapua cases, Varget and RL-15 and 90gr lapua and what velocity could I expect out of a 1-8 Hart at 27". Any help is appeciated .

With formed cases, start at 31.0 Varget and RL15 and work up.,We recommend 29.5 Varget for fire-forming). You'll probably end up close to 34.0 grains, but go up in .2 or .3 grain increments after 32.5 grains. Max Velocity should be around 3250fps using CCI 450 primers, based on a QuickLOAD projection, but you should monitor pressure signs on your cases. Max velocity will also vary based on your chamber, bullet seating depth, barrel etc. But there's a good chance you can hit 3250 fps.
