Will cut the flare about 2" back from the muzzle. This one has a bore of .985". The flare goes to about 1.750". Please contact me for photos, further info about configuration, and pricing.
My first buss was a 7-bore. It shoots 2.5 oz of shot or a 1000 grain ball. At 8 lbs, it's a hoot.
Look for videos on YouTube under customblunderbuss for video of the 7 and 4 bores in action.
Thanks,
Reign Clark
