I am trying to find out where to buy a Hevi-shot rated RSF choke. Can anyone help?
Unless you are planning on shooting steel shot out of it, you'll be fine with the new "lead only" chokes. I spoke to Remington about this and they verified you are fine shooting HTL loads out of them.
Did Remington make the HTL compatible chokes out of a different metal or is the internal geometry different that those chokes labelled "Lead Only"?

For one thing the lead only choke is supposed to be about .005 tighter than the Hevi-Shot choke.
The metal looks the same to me.
They are 570 and 575 I believe but could easily be wrong on this.
