Modern Rifle 6.5x55 loads
No, don't know of one. There's probably a good reason for it, too.
I personally wouldn't push the 6.5x55 past the 46,000 cup or 51,000 psi SAAMI limit, regardless of what rifle I was shooting, for two reasons:
First, excellent performance on game is had with the listed loadings. In fact, I have backed off from max quite a ways on most of my loads for 100 to 129 grain and still get superb performance on deer. Heavier game up to elk or moose would most certainly fall easily to the listed loads with 140 and 160 grain bullets. The extra kick and blast won't give you any appreciable increase in lethality or range. Why crank up an already darn good bolt of lightning?
Second, it is also the cartridge case itself, and not just the rifle, which must withstand the increase in pressure. This is most likely why you will not find any published data in the range you desire. The rifle may handle things fine, but the cartridge may exhibit backed-out primers, bulging, or split necks or heads. To me it isn't worth the extra 100-200 fps to risk those things.
There is no more humbling experience for man than to be fully immersed in nature's artistry.
