My 1 st editon load manual from LaserCast has several loads for that bullet.
what powder do you have on hand or available?
ie:10.8 grains unique=1302fps. max load is 11.7grains @ 1349fps
HS-6..10.8graiins=1044fps,the max is 12.0 @ 1170 fps
..yes,these two powders both have the same start loads.ie:10.8
SHOOT AT YOUR OWN RISK,I PROOF READ THIS 4 TIMES,BUT WE ALL KNOW 'STUFF HAPPENS'.I WILL NOT TAKE RESPONSIBILITY FOR THESE LOADS.
as to leading,I'd be inclined to use gas checked bullets at those velocities.However,leading can vary from gun barrel to gun barrel it seems.
..the manual does not show thes loads as being used with gc bullets tho.
