Bill emailed me a photo of a friend’s 2-bore rifle and another of the 2-bore balls. The first photo really gives a sense of scale.

I assume the bigger balls are for the 2-bore
and the smaller for another gun

The guy in the photo is apparently a big guy (so you get the sense of scale)
The rest in the above photo came with the gun.
A big thanks to Bill for the photos.

Leupold have launched a new scope called the UltimateSlam for shotguns and modern muzzleloaders. The SABR reticle can be adjusted to match your load.

SABR: Sabot Ballistics Reticle
Leupold’s® all-new UltimateSlam™ riflescope is the ideal combination of flexibility, accuracy, and durability for today’s modern muzzleloaders and shotguns. As an example of accuracy, using Hornady SST 2-pellet, 3-pellet and 12 gauge shotgun loads at up to 300 yards, the maximum error of the UltimateSlam is less than 1″ as compared to a 14″ error from the leading competitor.
