Went to the range yesterday with Bigcountry and had something interesting happen that hasnt happened before. I loaded up some new loads, Nosler 115 BT with 4350 and Win lrg rifle primers. I took all 5 recommended charges that the Nosler book recommends for 115 which was 45,46,47,48 and 49 gr. AND I took one load of 52 gr of 4831. This entire batch of ammo was to test a new seating depth. Well after I shot every group, heres the weird part......I had no bad groups, I mean some were .4 and some were .75 and some were 1". But usually when I test 6 different loads in one day I can narrow something down, but now I guess Im looking for some opinions.....Should I pick the overall tightest group period and load it some more, take the top 3 and load some more, or just say the hell with it and load the tightest group of the day that will give me the best velocity?
