Been a huge Trulock fan for awhile. It puts up good numbers but it's real finicky if it isn't squeaky clean.
2 weeks ago I switched to the .575 Carlsons and I love it. The numbers in my 870 are still 140-150 but the choke is very consistent, doesn't seem to be too picky and the pattern is the best i've found yet for evenness.
Can't go wrong with that choke.
