I just put together some 7x65r test loads pushing a Barnes 145 grain LRX with N555. Velocity should be somewhere around 2750 fps, but we'll see what we see. VV load data for the 7x65r is available for a number of their powders but not N555, so modest interpolation is involved.
Reloading for the 7x65r is interesting, in that it's a balancing act. The readily available S&B 173 grain SPCE load has a good reputation, is inexpensive, and regulates exactly to point of aim on my Sauer 3000 drilling iron sights, but velocity is a very modest 2450 fps, which is fine for your typical 125-150 yard shot at deer or pigs, but drops a surprising amount at 200 yards. My Blaser D99 has newer, better optics, and essentially functions as a single shot in deer hunting mode, and I wanted a load that I could confidently use out to maybe 250-300 yards, thus the load testing as VV data suggests that velocities of 2850-2875 with a ~150 grain bullet are attainable within pressure limitation.
The "balancing act" boils down to the fact that there are three common types of 7x65r fire arms: drillings, single shots, and double rifles. With a single shot, you can do just about anything that you want within barrel twist and pressure limitations. With drillings, you have to decide whether you want to keep your point of aim synchronized with your iron sights. With doubles, you have to achieve a respectable convergence between the two barrels, then also decide whether you need to keep your point of aim synchronized with your irons. It's a neat caliber, and it's a shame that more single shot rifles aren't chambered for it, as it has modest recoil and is very practical.
