I'm sure everyone here would agree that I'm some kinda nut for going through 4 different bases to get one that didn't need to be shimmed so the FF III dot could be adjusted low enough for correct elevation. I went through the Weaver 93A, Weaver multi slot, Burris 336 (hole pattern didn't work out), and ended up with the Warne 2 pc. steel base set. I used the rear base only and not only is it a clean looking setup, but I was able to get my elevation good out to 30yds. with a shotgun shell laser, and I've got more adjustment left if I need to adjust lower to get zero'd at 40yds., but I would guess I will need to raise the FF III dot a touch higher at 40 and that has never been the problem.
The only thing I had to alter or modify a little was the slot. It was just a little tight and the picatinny protector mount wouldn't sit all the way down without a tiny bit of grinding from the dremel.
I remember Rob Roberts told me in an email that he uses Warne bases when he does a setup on the SBE II. Maybe he had the same issues I've had with the other bases?
Anyway, I'm finally feeling good about my FF III setup since I found a base that I didn't have to shim up at the rear! Thanks Warne
