One would think, yes.
I only used the RZ600 with the one load (.338, 225-gn NAB, 2820 fps) but I have used a B&C with several different loads/cartridges. It was always fine out to 500 yds. Then again, my precision level was "minute of HIT on a 10" plate".
It's easy to get all math'matical about reticles; Stick gets all horned up that way about them. But there's a key to keeping it simple and this is what has worked well for me: zero your 400-yd hash mark on an actual 400-yd target. Now check where you are at just for grins at 100 yds.
If you do it this way, in my experience things work very quickly, easily, and simply.
While I wouldn't be above putting a reference hash mark on the power ring, if I just had to run a load that was way off from the reticle subtensions, that's a far different thing in the field than just cranking the power ring to the stop.
Just my opinion.
