Hunter,
Last Friday I purchased a Hastings for my SBE test patterened wih .Winchester HV 5 Turkey loads. I couldn't believe how the group tighten up compared to the factory full choke. It's all up to me now (aiming) and I'll look no further for a choke.
The choke is a Hastings extended Turkey Choke #b12660 cost me $29.99
I'll top it off with a Aimpoint and I think I'll have the perfect combination.
Have a good day.
