Sako 85 synthetic hollow stock

Evening all!

Do any of you synthetic stock owners have a method of making the hollow stock sound a little less... hollow?

When the butt brushes over coat zips and the swivel rattles it makes a frustrating noise.

Suggestions welcome.

Thanks.

Have you access to the hollow area?
Can you remove the butt pad?
One can fill with builders foam which can get very messy.
Or soak a piece of foam rubber in a thin epoxy resin, sqeeze out as
much resin as possible and shove foam into hollow. Resin will set
and have good dampening properties.
There are several other ways of filling but only a few that don't add weight like mad.

Thanks ejg,

I was toying with the expanding foam idea but have seen what it can do when in a confined space.

I would have said the above or if you want a wee bit more weight you can mix polyfilla with paint....sounds gash I know but once its in it will set rock hard...I knew a bloke who used to repair dings in his car with it years ago.
 
I wrekon best method is to fill with molten lead, will certainly stop it sounding hollow, not sure about adding weight though?

Sound advice tjwaines. You must be an acoustic specialist. Lead will certainly cure the hollow sound. Not sure how the plastic would hold up during the cooling period though.

Lead would of course be good if you wanted an amount of wieght but two points..it would melt the stock and also you would have to heat the internal where it was to be poured as if your didnt and a small amount of moisture was present then it would expand and whooosh..hot lead flying at you...not nice. Why dont you fill with an expoxy resin...one that sets over a number or hours...they are stronger than the 30 min ones...you can even drop lead shot into it if you need nore weight...or a recoil device... remember to plug any holes as it will seep through

Lead would certainly cut down the recoil down, as well allowing you to cancel your gym membership :lol:
 
Epoxy sounds like a good option then. I'll have to allocate some from the yard to project x.

Thanks guys.

Just curious - who has used the resin? Any pics?

DC
 
I will contact some of my engineering mates and see what they say...any chance you can take a pic of the void you need to fill, it will enable them to have a peak and then see what may be best...I know Devon is good but bloody expensive and noy the best for flow..will get back to you soon.

If you are honestly thinking of filling a stock butt with epoxy resin on it's own,
you might as well squirt the damn thing full with silicon from the DIY shop.
Might add 3/4 kg. I'd go the less weight route.
one possibility, cut pieces of styrofoam that fit into the butt and glue/fill with epoxy.

I got a reply from one of my mates and as happens got this reply...looks like wise words ..hope it helps.

Place a strong but pliable plastic bag in there and pour in some resin.
This will enable the void to be filled, the hollow sound to be rectified and as importantly, enable the solid plug to be removed...That is assuming the hole is tapered in the correct direction, if not this would be a permanent solution.

Having weighted a gun for competition use, I can say without any doubt that he needs to be careful adding weight to a stock, it changes the entire handling characteristics of the gun and if a permanent solution is rendered, would result in major work if the outcome went pear shaped...!

Why not fill part of the stock with bags of expanded foam beads. (Wall insulation beads) then inserts a bag with plasticine in it, then more bags of expanded foam.
This method would allow the bags of beads to be adjusted so the weight of the plasticine could be moved forward or backwards.
It will achieve the desired result without the permanency....great when he comes to selling it.

Hope this helps

Those bead can be obtained from a sewing shop, they use them in cushions annd bean bags, I think when I do my Tikka stock I will do it this way, I always thought resin was the way to go but this sounds the safer option.
 
Is hit possible to fill the stock with door/window instalation foam(spray) . Edi might know if that's safe to use. It fills all the holes, applies very easy and will be very light ( a few grams).
 
Hi guys. Thanks again for the tips. The resin we I have to hand is the equivalent of some C50+ concrete and just as heavy - or so it feels! The advice of chickenman's mate Tom sounds good and reasonable though.

Hornady, Did you buy your laminate stock for your 85 or with it? If you bought it after the rifle, where did you get it from?

Thanks..

I have been wondering about this recently. Not because of any scraping sounds, just interested in trying to make the T3 stock feel less.....plastic and hollow. Did any of the folk involved in the original OP try any of the suggestions or does anyone else have any bright ideas ?
 
I put neoprene but covers on my wood & synthetic stocks - cosy & warm - supports comb raising pads for improving fit (cheek weld) stops any scraping noise & protects the stock.
No need to mess about filling the hollows up & making the rifle heavier.

I think it may melt the plastic stock lol. try cold lead or lead #6 shot in resin or just use a large cake filling syringe and plug hole drill from the underside and let it flow ,but my 85 ist that bad but i wish i could find a better stock for it like a B&C ?
