Hello everyone

I am new to this forum but I have been reading other post and have started developing a load based on other posts. My rifle is a hart barreled 7 mag with a 27.5" barrel and 10 twist. I am using twice fired and neck sized norma brass. Federal 215 match primers. Berger 168 vld hunting bullets and Retumbo powder. This is a hunting rifle so I wanted to start 40 thou out of lands to develop a load so that it will fit my magazine. 71.5 grains gave me a 1" group at 100 yds and 3130fps. I worked up two more loads at this powder charge backed out 80 and 120 thou. The 80 thou produced a 3/4" group at 100. Should I start stepping down from 80 in 10 thou steps? Should I work on both sides of 80 thou? Not sure which way to go from here......
