I would be more interested in buying a top qualitycustom choke like a Back Diamond Strike from Indian Creek. Then.... you can get serious about shooting the worlds tightest Hevi-13 patterns. Do your research and the above mentioned choke with Hevi-13 loads and you will see they dominate and hold nearly EVERY N.W.T.F World Record at the championships.... in every class! Simply awesome patterns!
Good luck and good shootin'
