I bought a few boxes of 3" federal HW #7 to shoot out of my 12 ga. winchester 1300. All of the chokes I cerrently have for it are ported. I currently get a good hunting pattern from a .660 rhino choke but I know trulock specifically designed a choke for these federal HW shells. The trulock for these shells is a non-ported .650 and is the exact same choke as their TSS #7 choke. Carlson makes a non-ported TSS choke as well but it is a .640 diameter. I am having an easier time locating a carlsons but I am looking for some recommendations between the two chokes listed. Will the .640 be a little too tight and I should just keep looking for the federal HW specific trulock .650 or will they both be fine for these shells n my Winchester? Has anyone on here ever compared the results between these chokes in their gun?
I have a Remington 870 21" barrel. I shot the old federal heavyweight 3" 7s out of the carlsons tss .640 tube. It's throwing 160-180 in a 10" circle at just over 40(42) yards. I shot one of the Federal 3" TSS 9s out of it and got 321 hits. My Trulock Federal 7 .650 choke just come today. I plan on shooting the same shells through it this weekend, weather permitting and I'll post the results. It was near 70 the day I shot the Carlson, and it'll probably only be mid 50s when I shoot the Trulock. So not a 100% fair comparison, but the best I can do.
First two pics are the old heavyweight 7s out of the carlsons .640, last pic is the new heavyweight tss 9s out of the same choke.

Borden, thanks I really appreciate it. The pattern with the HW7 in the .640 looks good to me at 40+ yards. Nice and even with no large holes. I would be content with that for sure. Please post back with the trulock results when you shoot it. I am looking forward to the comparison.
