Yes, I've had a quick look around the castboolits site.

Well I tried loads with AR2205 (IMR4227 equivalent) and they went completely sideways but otherwise "grouped" within 4MOA at 50 yards.

I then tried AR2207 (IMR4198 equivalent) and these worked properly ie round holes in the target. They did about 2 1/2 MOA which is about as good as my Trailboss loads with the 405gn. I've not sure how fast they were going but they did give some boot (similar to a 308?). No leading at all and burnt very clean. (I use magnum primers but no filler and seat the projectiles well into the case ad use a light roll crimp.)

The load of AR2205 I was using was supposed to give around the same velocity as the AR2207 loads - obviously the pressure curves make a difference to the performance, assuming they are doing the same velocity.

Anyway more load fiddling to do and slower powders to try (to fill up some of that space in the case).
