    What's the best place, currently, that will do a great job on lengthening (modest) forcing cones ?

    Thanks!

    Appreciate that T. Wilkinson is 'the' barrel guru - but he doesn't lengthen forcing cones.

    Unfortunately, the only time you can truly feel the difference of boring out your forcing cone is after a trip to the urologist.

    It reduce felt recoil. All of my Perazzis have this. Most anyone can do it, but it should be done professionally so the tapered area is polished and not left in the raw-cut mode.

    Kerry Allor is superb in South Shore MI, or Briley in Houston.

    Any gunsmith can lengthen your forcing cone. It's not rocket science.
    You ream it and then polish it. Pretty hard to screw up.

    Ahem...

    1. Lengthening the forcing cones does not reduce recoil...it simply enhances pattern saturation with the right shot size.

    2. If you are going to do it, make sure you have a "big name" gunsmith do it, because most people are very leery of cone work by marginal gunsmiths.

    3. If you shoot a lot of hot reloads....sometimes, crappy cone work goes: KABOOM!

    4. Reducing wall thickness at the chamber is not a very good idea. You are better off buying a gun with a longer forcing cone from the factory (more wall thickness).

    I would contact the best Jim Eyster at (740) 625-6131 and tell him your shooting needs and discipline.

    Here's his location:

    Lengthning a forcing cone certainly DOES reduce felt recoil.

    Think about it, the shot charge leaving the hull, narrowing down from the chamber diameter to the bore diameter see a more gradual taper. Not only does it reduce felt recoil, but you see less shot deformation in the crunching as the wad & shot enter the barrel.

    When/if you do decided to have this work done, be sure to ask if the polishing is doene, rhather than have the raw metal cut left. Polishing helps to reduce wad build-up.

    Ok, I am thinking about it. If the shot charge sees a more "gradual taper" and there is less impediment for the shot then shouldn't the recoil increase, not decrease. How does the shot hitting the forcing cone increase the recoil?

    How do you know there is less shot deformation?

    Johnny, maybe it creates a pressure spike?

    do it just ahead of the chamber.

    Whiz has the correct idea to create a "more gradual taper."

    If you look at the evolution of beretta barrels, you will see that from mobil choke to optimma the forcing cones continue to get longer.

    Rumor has it that the new DT11s will have an even longer forcing cone, but I've only seen that posted on TS.com.
