- : Oh, yes --- and recoil suppressors (the kind that get built into the
- : stock). Any recommendations? Good/bad experiences?
-
- There are a lot of recoil suppressors that get "built" into the stock. They
- can be broken down into 3 groups:
-
- 1) Weight/spring These are the Breako's, the C&H, the Dead Mule, etc.
- They amount to using mass and/or a spring to widen the recoil pulse and
- in some cases, re-direct it via an angled deflection of the mass.
-
- ADVANTAGES: Easy to install, most require drilling a 7/8" or 1" hole
- in the stock parallel to the barrel and dropping them in.
-
- Cost is around $50 retail.
-
- DISADVANTAGES: They are only somewhat effective.
-
-
- 2) Air/Oil damped moving butt. The two biggies here are the Counter Coil
- and the Soft Touch. They are basically oil or air dashpots (shock
- absorbers) with internal springs to return the butt to it's nominal
- position.
-
- ADVANTAGES: They work very well. Since there is a dashpot involved, the
- recoil is spread out over a longer time but some energy is
- also dissipated.
-
- Both brands may be made to incorporate "sliding combs".
- In this arrangement, the comb and the part of the recoil
- reducer which contacts the shoulder are fixed and the gun
- "slides" under the shooters face. This is very
- comfortable to shoot.
-
- DISADVANTAGES: They are difficult to install. The Counter Coil and the
- Soft Touch both require the stock to be shortened approx.
- 3/4" to retain the original length of pull. They also
- require 3 somewhat precise holes to be drilled
- perpendicular to the butt of the gun. Not an easy task
- without a jig and a mill.
-
- Expense. Typical installation of the reducer is $150 -
- $200. If the sliding comb is desired, tack on an
- additional $150 - $300.
-
- Both the Counter Coil and the Soft Touch collapse if the
- gun is held tightly to the shoulder. People who use them
- get used to this and have good luck with them. I
- personally find this annoying.
-
-
- 3) Counter acting impact device. This is the device manufactured by
- Browning and installed by them in their BT-99+ and Citori+ only. The
- device is basically a giant automatic center punch. It consists of a
- weight with a hole in the center and a small plunger held off to the
- side of the hole by a conical spring. As the conical spring is
- collapsed, the mass is pushed back against a spring until finally, the
- plunger moves to the center of the hole in the mass and the mass "snaps"
- forward. This causes the recoil to be spread out into 2 small, wide
- pulses rather than one large one.
-
- ADVANTAGES: They work very well. Effectiveness of this system is as
- good or (in my opinion) better than than 2).
-
- The difficulty to install is between 1) and 2). Only one
- hole needs to be drilled but it must be recessed so a
- mill is still very useful.
-
- Unlike the systems in 2), the portion of this system
- which contacts the shooter's shoulder is very stiff and
- will not collapse when the gun is held tightly.
-
- This system may also be made to incorporate the
- "sliding combs" but as far as I know, only one shop does
- this, mine!
-
- DISADVANTAGES: Expense. Typical installation of the reducer is $150 -
- $200. If the sliding comb is desired, tack on an
- additional $150 - $300.
-
- I have installed all these systems in various guns and have shot nearly all
- of them. I have chosen the Browning system for all my competition guns. I
- like the stiffness during mount, especially when I shoot sporting clays
- since uniform gun mount is important and it is difficult to get a uniform
- mount with pieces that move.
-
- Let me know if you're interested in having me do the work for you. I
- really don't advertise on the net but this is such an extremely good fit
- with most of the work I do, I couldn't resist! I'd recommend looking
- around locally since I'm sure there are 'smiths there who will be glad to
- take your money.
