Just thought I'd throw some results up for others shooting this caliber. 107 grs Rel. 25 gives 3068-73 fps. 108 grs goes 3099-05 fps. Pressure looks mild, primers are round. This is with the 250 Nosler. Groups weren't too good at around 1 1/2". The show ponies were thw 210 TSXs with 114 grs Rel. 25. Not chronoed but several sub inch groups so far.

MTM is that a factory setup, or aftermarket?

I don't shoot the Barnes anymore, but back when I was shooting the 210 XLC's, I could get 3500 fps. with them out of my custom rig w/ a 29" barrel. RL25 and Retumbo have really turned out to be my powders of choice in that gun. I need to get my hands on some AA8700 as well, since it really liked H-870.

Update to the above post, the 114 grs load is doing 3450 fps. 3/4" at 100 yds.
