I'd like to increase the length of the forcing cones on my 3 870 barrels.

Although I'm a fairly skilled amateur gunsmith I'd like to discuss the possible problems I might encounter.

I'll be using Brownell's Long Forcing Cone Reamer and following their instructions.

How much recoil reduction can I expect if any?

Hans vang comp package i believe will reduce recoil approx. 15% I think this is only with lengthening cone as porting would only reduce muzzle flip, I also heard that you develop a feel for how much to lengthen with the tools your using, after a while. Hope this helps.

I had this done on a coupla 870s. I dunno about recoil reduction,but patterns did improve.

The only time 12 ga recoil bothers me is sighting in with slugs at the bench,so maybe I'm not the one to ask....
