Of all the pattern pictures that I'm seeing for the federal heavyweights TSS #9's, are these patterns from the 1 1/2 or 1 5/8 oz loads? I never see that specified and was curious if anyone using the federal had a preference.
I'm shooting a youth model 870 with a 21" barrel. Still haven't made a choice as to which chokes to try, but based on availability- I'm leaning towards the federal hw TSS route. Thanks so much!
