Weighting a CFX

[Gamo X-Ring Shooter]

I shoot competitive small-bore rifle with a 13 pound gun and have never really liked shooting my CFX much because it just seems too light to me.  So today I got the idea of weighting it kind of like they do on AR-15s for high power shooting by putting weight in the stock.  I took the butt off and filled it with zip-lock bags of sand.  Now it feels really nice like I want it but was wondering if that extra weight will screw with the accuarcy of the gun.  I could tell from the first time I shot it that the recoil was dampened somewhat and not nearly as harsh.

Hey Brian,

You know how moving the barrel weight will change the harmonics if the barrel, sometimes for the good. Well changing the weight of the stock can also change the harmonics of the rifle, sometimes for the good.

Many of those that own the CFX have filled the stock with "Memory Foam", from the fabric store. They quieted down the "noise" from the spring and piston, and they all seem to think that it was a great improvement.

I don't think that your extra weight will harm accuracy in the CFX, you'll need to try it out to tell for sure.

Hey Brian (whoops, I almost added a 'y' by accident ;~), one thing you might want to consider is double-bagging that sand. I'd hate to have a busted bag pouring sand through that hole at the front of the cavity into the trigger area of my CFX. But it doesn't sound like the extra weight should hurt your accuracy any and could potentially help it.

I'm sure it's been thought of before, but I've wondered if the same thing could also be accomplished by fixing into the stock cavity one or more of those recoil dampers that archers attach to their bows to absorb the shock of loosing an arrow. In times past they were made up of a sealed capsule enclosing a big blob of mercury that "exploded", as I recall one of the advertisements saying way back in the '70s, within the capsule, thereby absorbing some of the shock, and were mounted to the bow with a short threaded stud. A similar type of stabilizer/recoil damper is still available from several manufacturers, but the ones I have seen in the catalogs use a gel-type shock absorbing medium, probably due to environmental concerns.

On the other hand, sand is definitely more available, and easier on the wallet if it doesn't suit you.

I used electricians duct seal to fill mine, stick a plastic produce bag in the stock first, then start packing in duct seal.  If you pack it full, you can get close to 2 lbs. in there.  I've done it to 2 CFX's and a Shadow 1000, accuracy improved in all, but I can't say if the improvement was in the gun or the shooter :-).  Good luck.

I didn't like the front end heaviness of my CFX so I put in about 3/4 lb of lead buck shot in double sealed plastic bags.
I stuffed the stock with plastic bags first then put the buck shot in last - now she balances very nicely.

Mine is now gas rammed so there's no twang anyway
