We do a good bit of card/board shooting in this part of the world. There are all kinds of combinations that seem to work. Long-barreled 835s, most non-ported but some ported work well in most of those shoots. Most of what we see are custom chokes, non-ported but factory chokes ported and non-ported occasionally show up at some shoots.
I've used the older Wright's limited production 835 chokes (early discontinued models) that are non-ported and very smooth inside with excellent results. Our shoots are generally 60' and we use #9 shot. They will blow holes.
Thanks,
