I do not own an ULW, but my 7mm Wby has a fluted tapered #2 barrel, with the topper ware stock, and it is much lighter than my regular Mark Vs, and the recoil is manageable. I am by no means a big man, at 5'5" and 158lbs soaking wet, and I don't mind shooting a box of ammo. Now, not everyone tolerates recoil the same way. So, I'd suggest you shoot it without the Accubrake and then decide if its necessary or not.
