Re: what choke for a rem 870?
I have used the Tightwad (.660) and the H-13 (.662) with H-13 7s. The H-13 choke edges out the Tightwad in my shotgun (within 3% of each other). I have not shot the Truglo Gobble Stopper choke, but that is because of the choke diameter (.665). The .660 diameter tends to average 10% denser patterns than the .665 diameter for me.
With H-13 6ís, I only see a 2% increase in pattern density using the .660 constriction vs. the .665.
I met the world's greatest hunter, and he never once told me he was.
