Bought a Topper slug barrel from Gendoc, and fitted it to a frame I had extra. Could not use my boresighter, as I don't have a large enough pilot, so at the range I just put up a poster board at 15 yd.s and fired off a shot. This gave me reference to boresight. From there I moved the target to 50 yds. and fired one. Two scope adjustments and then a three shot group with all three touching. This is with Remington premium sabot slugs. Best accuracy I've ever gotten with a slug gun. There was a water jug back on the berm at about 120 yds. I aimed for the neck, and was satisfied by a large geyser of water.
I will use this for hunting on public land where only slugs and muzzies are allowed.
Now if I can just wait until October.............
