I did some first time load testing with my Rem 700 Titanium 7mm SAUM today. I was using 139gn Hornady BTSP with Rem 9 1/2M primers. Ordinarily, I'd use 140gn Accubonds when hunting but the 139gn Hornady BTSP gave me the info I needed to start out. These chronographed loads are all a 5 shot average. The RL19 loads were a bit of a dissapointed but I liked how the RL26 performed and could probably load a little more powder with that combination. No loads produced stiff bolt lift or ejector marks on the case head. Luckily I still have a few unopened bottles of RL26 left over from when I had a 270 Winchester so all is looking good.

60gn H4350... ...3109 fps
61gns RL19........2879 fps
66.5gns RL26....3174 fps
60gns W760.......3139 fps
59gns RL17........3142 fps
