Partagas, I shot the 87's at 3550 with 45.5g of Win 760 with a CCI 250 primer, accuracy was .300 or a little less.
This was an absolute MAX load for my rifle, so I would start off at 43.5g and work up in your gun.
My rifle had a 1-12 twist, so the pressure will be a little higher in your rifle...take that into consideration also.
What was interesting was that there was much more copper in my barrel after shooting the 87's at 3550 than shooting the 70's at 3850. I rarely ever shot anything past 450, so I stuck with the 70's.
Good luck and let us know what you find out works well in your rifle.
