I tried some of Simpson's loads in my 760, and was not impressed. Using the 180 grain bullet, I was not able to get 37.5 grains of RL-7 in the case. I topped out at 36.0. Anything above that and the bullet started backing out of the case. I took a deer with the load and he piled up about 30 yards after I hit him, typical of the woods loads I have used in .30-30, .35 Remington, and .44 Magnum. The .35 Remington is fine just as it is, and hotrodding it is not a useful endeavor.
