I use the Hornady 165 grain SP interlock bullet for some 35 years ,my powder of choice IMR 3031 .I used this load in A3-03 springfiels since 1968 and have say never lost a deer with load.I just pick up a H@R Handi -for $179.00 and seem to favor the same load .The above target is at the 100 yard with 3 shots a little under 7/8" IMR 3031 44.5 grains of powder
