Anyone have experience with flex honing a 410? This is a last ditch experiment before the little SXS is either sleeved or rebarreled.
It is English, 2 1/2 inch chambered, peninsula lock hammer gun, round actioned, very cute and worth saving .
I gave up on flex hones years ago. I now use a modified Sunnen hone. I have not tried such a small diameter tube but I would look into the options they have to offer. I can send you pictures, and maybe an article on this system if it would help you.

SKB thank you for the info. Around here a Sunnen honing head is about the same cost as sending it for sleeving in Italy. That is the reason I thought of Flex Hone as an experiment before resorting to more drastic measures.
I will look for other alternatives for honing heads and see if something more affordable surfaces.
I just use a mandrel and stone from the Sunnen set up.
This is for a larger size than you need but 40$

I’ve never had much luck with a flexhone. It just seems to polish the roughness. Or as a friend said run it for an hour and you might remove a .001 of metal. Safe for hobbyist because it does not do much very fast and our attention span is very short. We give up before we screw up anything.
A few years ago I was looking into optimizing a .410 of mine. Aside from extending the forcing cones and enlarging the barrel bore diameters (I forget how much). The final treatment was to put a high polish on the newly extended forcing cones and enlarged barrel bores.
I never had the work done on my gun so I can't say how much it helped, though it did make sense. BTW, the gun was a Rossi Squire (a Walmart special) I'd cosmetically worked over. I called it my Sow's Ear Project. Unfortunately, it just wasn't worth it to invest that much money in the gun.

Interesting re the mandrels. Our local dealer had quoted 450 Euros for the mandrel and extra for the stones.
I have had a lot of luck with emory paper, a split aluminum rod, and lard oil as a cutting fluid, If the pitting is very mild Frountier gun shop sells a stainless steel pad that will clean up very mild pitting when turned on rod with a drill.

ChuckH has solid proof of how much very long forcing cones help a .410.
