They are pretty good loads but unless you get old stock they use the flight controlled wad, which means you need to use a none wad striping choke like a factory one, old school Undertaker or one specifically designed for it.
I use to shoot them from my 870 when i had it using a $20 undertaker choke with very good results, actually liked it the best from the lead group. Havent shot it in a few years though so not sure if anything has changed in their loads.
