Re: 265 gr. Lapua/Edge data TSX needed
I was remiss in not mentioning I was using Hornady brass. I bought 40 cases from 3rd Gen S.S. (sponser here). I was not optimistic really as the Lapua brass has proven to be superb. This Hornady brass is pretty good stuff, I was surprised. I've got a set of 20 cases with ten firings and they are still going strong. They weigh a bit less than the Lapua so loads may have to be reduced a little for Lapua brass. Also, you will run out of powder space sooner with the Lapua brass.
Like I said, I ran out of space at 94 gr. Retumbo so am trying some faster powders next. I got no signs of excess pressure with the 94 gr. Retumbo load and 2855 fps. Accuracy at that velocity was not very good, about 1.6" @ 100 yds., but this was apparently between nodes as I had some lighter charges producing just under .5". Next I will be trying RL-22 and Ramshot Magnum.
I would not be surprised if 2850 fps is about tops for my rifle though. It is a factory Sako TRG-S (M-995) with factory Sako tube, which I believe is only 24.5". The online specs say 26" but I think it is less. Guess I'll have to measure it. The specs also say 1:12" twist and that is incorrect. Mine is a 1:10" twist, thankfully.
