You are probably looking more at minute of target than you are minute of angle.
You will develop a feel for your personal recoil limits which may or may not be greater than the limits of your new weapon.
You are getting some 260gr LBT WFNGC from Montana BulletWorks, which should work fine at any velocity you "choose" to shoot it "within your own personal limits." Because it's Veral's mold, let's put it on his terms. His DV says it needs a minimum near 1150fps (at the muzzle) with a 44Mag WFN to work properly on live game. The maximum DV comes a little over 1450fps. You get to decide where in that range from 1150fps to 1450fps do you want to operate to take best advantage of Veral's technology. Accuracy, recoil, etc can play a part in your decision. I'll go out on a limb and say you might do just as well with Plain Bases in this velocity range, expecially closer to the lower end. That's the direction I'm taking with my 45Colt Bisley Blackhawk.
I was shooting Keith bullets before I ever heard of Veral Smith, but I do think he's got something going with his WFN's and what is needed to make them perform on game. I've digested his book. Happy hunting!
