View Full Version : Slugs in a Rem 870?

March 7, 2009, 02:38 AM
I can't seem to determine what kind of choke I have on my 870 Express Synthetic - 18" barrel. I thought it was suppose to say on the barrel what kind of choke but it doesn't. The reason I'm asking is because I want to shoot slugs but I read that if it has the wrong kind of choke, slugs can ruin the barrel. When I look down into the barrel it looks smooth...can I shoot 00 buck and slugs in this? Thanks for any info...

Nearly all 870 barrels of 18" length are cylinder or improved cylinder bore. There are a very few that have rem-choke (interchangeable) chokes. Police/riot barrels are made to live on diet of "buck & Ball", your barrel should love this diet.

Check to see if you have a Rem-choke barrel, "funny looking" slots on the crown of the muzzle, if so get the right wrench, remove it and check for it's restriction on the outside body of the choke (extra full or turkey don't like slugs), reinstall the choke. If you don't have a Rem-choke barrel, then just shoot away!!!

Good luck with your Express, and be safe.

Asked and answered, but I just wanted to say that I also just picked up one of these - an 870 Express Synthetic with the mag extension. Very nice shotgun and the price is nice too!

Does yours have an unlabeled fixed choke barrel?

^^ It is fixed cylinder, stamped with the usual Remmy markings...

If you have a method of measuring your bore, standard US choke sizes are:
Full .035"
Mod .020
IC .010
Skeet .005

OGD.... For those not aware of these dimensions I will add this...
Those numbers above are how much smaller the choke is than the bore so a skeet choke is 5 thousandths smaller than open cylinder and a full is .035 of an inch smaller than cylinder bore...
cylinder bore is .729 inch so you subtract the above dimensions from the bore.
