Shot out of RRA LAR8

Well yesterday morning I loaded up 5 different loads with slightly different powder amounts. All using Hornady bullets, IMR 4895 and WLR primers.

5 rounds with 178 grain HPBT at 39.6 grains (1.5 inch group, shooter aided)

5 rounds with 178 grain HPBT at 40.6 grains (.5 inch group)

5 rounds with 178 grain HPBT at 39 grains (1 inch group)

5 rounds with 165 grain SST at 40.5 grains (.75 inch group)

5 rounds with 165 grain SST at 40 grains (.5 inch group)

What was amazing was the amount of difference where the 165 grain bullets impacted up and down vs the 178 grain bullets. I have never really played around with different bullet weights but they make a big difference at 100 yds even.

I don't have 100 rounds through the gun yet but it is shooting as advertised that is for sure. I will post a few pics of the best groups.
