Chambers Lengthen?

Reduce your velocity and that will reduce your recoil.

Gentlemen,

Short chambers and/or very short forcing cones can cause a significant increase in perceived recoil in SOME guns. I experienced this with a Lefever DS 20 gauge and another well know PGCA member recently had a similar experience with a Parker 10 gauge. Lengthening the chambers tamed the recoil in both guns.

In most cases short chambers won't cause any noticeable increase in recoil. To verify if the perceived excessive recoil is caused by short chambers first try shooting the same equivalent load (shot load weight and muzzle velocity) in the appropriate length shells for the chambers. Also have another shooter or two try both short and standard loads in a blind test.

There is also the possibility that different shell/load of the same equivalent will NOT cause excessive recoil. Try a few different brands and find out. The thickness of the case/hull walls can be the cause of excessive recoil. Winchester AA and Remington RXP have thinner walls than lower cost shells. A thicker case wall may cause the payload to be forced through the combination of extra case wall and sharp forcing cone. A raise in pressure may occur in this example. In rifle cartridges seating the bullet into the lands rather than allowing a short "free-bore" increases pressure. If measured, the same may be true of a standard shotgun cartridge being shot in a short chamber WHEN excessive recoil is perceived.

If necessary, rather than lengthening the chambers the forcing cones could instead be lengthened. I occasionally shoot 3" shells in 2 3/4" chambers for which I have lengthened the forcing cones with no . This insanity caused no excessive recoil other than the increase from the heavier shot charge and velocity of magnum shells. Lengthening chambers or forcing cones can reduce perceived recoil IF excessive recoil was experienced. Before you modify anything, first conduct a controlled blind test as described above.

Respectfully,
Mark

Thank you very much....GREAT ADVICE! I will give these a try. I do enjoy the "CARRY" weight...It just is not enjoyable after 50 rounds...I catch myself "Flinching" THANKS!
