Gregg Reed and I have been trying. No luck yet.We have found a place (Krieger), to get barrels made to the bore
size that will work best with our brass cases.Between
.980 and 1.00 inches. We will have to get tooling set up with them.I have a heavy barrel on hand to get reamed out and rifled for 4 bore.Gregg's buddy is working on his barrel machine also.Are there anymore of those 4 bore
Imperial cases around?? I like to get one to measure and
compare to ours.ED.
