I polished my 870 20 several years ago and think its time for a touch up. I can't find the20 gauge shell I used to center the cleaning rod, on my 12 I used a 20 on the other end but can't remember what you use on the other side of the 20 unless a .410. I re read the sticky and didn't see anything about it.Anyone remember?
Thanks
Yep, I used a .410 built up with a little electrical tape. Insert into the 20 hull and you're ready.
