When you send it all off be sure to specify SSK, Virgin Valley, or Bullberry spacing on the new screw holes. This will give you more freedom if you need to switch to a steel base later. I have had a red-dot sight mutilate a Weaver base, now I'm using one Bullberry 6-screw steel base and three VV 6-screw SS bases. Everything smaller than 30-30 Improved still uses the Weaver 4-screw base.
Having a "Pachmayer Decelerator Gripper" grip will calm down the re-coil, it makes a big difference when shooting a caliber that has some punch, I highly recommend it.
