RKS,
Hodgdon's Lil'Gun is what I use. I am using a 40 gr. V-Max with 12.5 gr. of Lil'Gun. Velocity is 2915 fps, and accuracy is terrific! OAL is 1.80" in order to fit in the rotary mag.
Am working up loads with Lil'Gun and the WW HP. Tried 12 gr., and primer pockets got loose, so I am backing off to 11.5 gr. to check.
I have also tried 10.6 gr. of W-296 with the WW HP. Velocity is around 2600 fps, and I have not tested for accuracy yet. Accuracy with the Winchester Factory 46 gr. HP loads is pretty good, and is around 2500 fps. I expect that accuracy with my handload will be decent. OAL on this load is 1.75"
VAfoxhunter is right--I use the Lee FCD, and neck size after the first loading!
I have shot one coyote with the V-Max load this year, and I hit her too far forward on the shoulder. Was not too pretty, but had I done my job, I am sure the bullet would not have exited and been a DRT.
Good Luck!
Tim
