As the owner of both a 300 weatherby and two 300ultramags I find that there is no real difference in felt recoil.Rifle weight is very close but the weatherby has less weight in the barrel so they balance differently.My ultramags how,ever do produce over 125fps more velocity than my weatherby with both shooting handloads.My weatherby produced a maximum of 3250fps while my ultramags produce 3375fps and 3395fps both with 180gr bullets.
