I had the standard XVR which Tig now has and with a max load of H110 from the Hodgdon loading manual and the 260gr partition I was getting right at 2000fps and shooting MOA at 150yds off sandbags. I used the Warne steel mount and three Leupold Rifleman vertical split rings and a Leupold VXIII 2.5-8. I used the same set up on my 500 S&W and never had a problem of any kind and accuracy was similiar.

I won't be wronged. I won't be insulted. I won't be laid a-hand on. I don't do these things to other people, and I require the same from them. John Wayne-The Shootist
