Hi Ed. I had Seminole in Fla lengthen the cones in my Citori to 5". The reduction in recoil was very apparent. After the cones were lengthened, I've never switched out the I/C chokes as the patterns became denser and more even. I had the cones on my Iver Johnson Hecules lengthened and the recoil reduction was apparent. The front trigger no longer bloodied my finger when shooting the back trigger. I bought a reamer and did my 20 ga Savage single shot and again saw a recoil reduction and the patterened tightened noticeably. Regardless of what the other guys might tell you, I'm a fan of longer cones.
