Filling a rifle stock

FireFighter5318 · September 19, 2018, 05:13 AM

Im not sure if this is the appropriate place to post this but has anyone ever filled a stock with that kinetic sand kids play with if so what were your results

New to me, what is "kinetic sand"?

I have seen folks fill rifle and shotgun stocks with mercury recoil devices and these seem to work decently enough.

In preparation for a handicapped muzzle loader hunt, I had to make a .50 manageable for a smallish 13 year old. I filled the hollow synthetic butt with dry sand(graded sandblast media to be precise), tamped it in solidly, capped the hollow with epoxy, and added a soft recoil pad. Even with the 24-26" barrel, the rifle came out feeling muzzle light and manageable both physically and recoil wise. IIRC, it added approx 10-11 ounces to the total weight.

That sounds good to me i have a model 70 in 300 win mag and im looking to add a bit of weight and hopefully the sand will soak up a bit of recoil.

Then look at the mercury devices; they not only add about 8oz, they dampen (elongate) the recoil pulse to make it feel even softer

FYI, the Germans use wolfram in their delayed blowback roller locked G-3/MP-5 firearms.

Wolfram is TUNGSTEN in English

"...looking to add a bit of weight..." What stock material?
"Kinetic Sand is a registered trademark of Spin Master Ltd." Makes it a marketing thing
98% regular sand. 2% polydimethylsiloxane which is a plastic.
"...does not stick to other materials and surfaces...and does not dry out..." Means it's really no good for firearm applications. Won't stay in place.
Wolfram the element is AKA tungsten, but tungsten is used in assorted alloys and is hard to machine. Melts at 6177°F.

Actually, tungsten is pretty easy to machine. But it is relatively expensive. My question would be why re-invent the wheel? If you want weight in the butt of a Model 70, add a recoil reducer or just lead shot mixed with epoxy.

Are we talking a wood stock or one of those hollow synthetics? I did a Winchester stainless Classic in .338 Win. Mag. that had a hollow synthetic stock by adding a pound of lead into the forearm and a half pound into the buttstock to help with balance. Rifle weighs a ton but the recoil is right pleasant off the bench.

It's the factory hollow synthetic stock and in that case where would i find lead shot?

FITASC · September 20, 2018, 09:00 AM

trap/skeet clubs, big box stores with reloading supplies, all sorts of places can carry lead shot.

**4V50 Gary** · September 20, 2018, 09:08 AM

I'd find a shotgunner who reloads shotshells. Then it's a matter of finding a tube that will fit the hollow of your stock (or sewing a small tubular shaped leather pouch that will fit into the hollow of the stock).

FITASC · September 20, 2018, 09:25 AM

Or, doing like I suggested earlier and getting a C&H recoil reducer

sand and epoxy is WAY cheaper

Mercury recoil suppressors are awesome and probably better than kinetic sand.
