Question RE: Rifled chokes

I'm getting pretty good accuracy from my new 870 cyl. bore w/bead but I was wondering if accuracy would improve with a Rem. rifled choke? Does the extended rifled choke have more rifling than the flush mount rifled choke or is it just designed for easy install and removal only?

Extended rifled choke has rifling the full length, so it has more than the standard rifled rem choke. I need to run some slugs through each of mine to see if it helps with accuracy. Dave McCracken here, and a local old salt police officer friend both recommended running a rifled tube even with rifled slugs for better accuracy. Give one of the rifled tubes a try and see how it does for you.

Make sure you use anti-seize on the threads, you'll bust a gut getting it out if you don't.

A rifled choke will probably help accuracy, but it's not a given how much.

The rifled, flush tube I use gives me less than 4" at 100 yards. Switching to an IC tube opens things up to 6" or so with THAT slug. A different slug through that barrel and tube comes in around 5". Go figure...

An inch may not sound like much, but an inch at the bench works out to 2 or more inches in the field under adrenaline boost and shaky positions.

I've not seen any rifled or Brenekke slug that failed to benefit from a rifled tube. My tests are not that extensive. I found what works for me and use it.

HTH.....

Thanks for the responses
