Daryl,
Thanks for the tips!
I have been wanting to try Rb on my shotguns but they are full or half choked.
For full choke, If I can underestad you correcty, your advise is to use a ball-patch combination that pass throug the choke? Easy or snug?
What about my .575 RB for the 20ga.
I have not try it yet because Im afraid to damage one of my beloved guns.
Thanks
Martin
