I just finished building up a VZ-24 98 Mauser in its original 7x57. E.R. Shaw made me a deal on a new barrel and all of the work. Shaw told me to provide a Redfield or Leupold one piece steel base and they mounted it. It fits over the clip charging hump.
Anyway, I'm trying one of the new Redfield Scopes. At 100 yds it hits 7 inches low with the elevation adjustment maxed out. This means that the back of the scope needs to be higher (opposite of what you first imagine). From reading online, a 0.10 (ten thousands) shim will raise impact 10 inches at 100 yds. I think I'll go with the 0.12 to raise impact 12 inches so that I can crank the elev adjustment back down to about the middle. Does this sound like a plan of attack? I'll have to trim the shim to size. On the other hand, a fellow at the range today told me to look into Burris Ring inserts. Comments??? I've never had to do this before.
