It is a sinle shot and it is a little harder to pop open. What and where do you classify the webbing on a cartridge.
I am still having trouble with this barrell, it went from 4" groups to 2" but thats it.
It wont do any better and the 3 loads it did the 2" groups with were hot loads. 2.5 gr lower it opens up bad.
But I have only tried two powders. W 760 and Varget. Any idea which other powder I should try.
