FL/GA Hunter-I can' t tell you anything about bullet performance.The blr and 721 belong to two friends from work that decided to have me work up handloads since the light magnums grouped so poorly.Both delivered an inch or under with handloads which was less than 1/2 the size of the light magnum groups and better than any other factory loads tried in those rifles.The owner of the remington pump decided not to use the light magnums because of the pressure signs which were shiny spots on the case head with sticky extraction.The owner of the a-bolt was a stranger who I have never seen again.
