What, if any, is the difference between a BR and HVR trigger if they are both set at 1.5 oz. Other than the obvious of the BR not having a safety. I picked up a HVR for a smokeless muzzle loader build and like how easy it is to switch one spring and set it really low for load work up and then heavier for hunting. Got to thinking is there any reason to not use the HVR in a f-class rifle set low and then have the flexibility to bump it up to a pound or two for some varmit/long range hunting? Or is there some clear advantage that the BR trigger has at the really low pull weight settings.
