Anyone have any good ideas for filling a synthetic rifle stock to add some weight?
I have a CVA Hunterbolt Magnum .50 muzzleloader that I just know is gonna knock the tar out of me as I start building up a hunting load.......geez that stock is light!

Here is my idea........remove the recoil pad and fill the entire stock cavity with spray foam insulation, and while still wet maybe insert a couple large stainless bolts that will sort of float in the foam when it hardens.
Should add some weight and take a bit of the bite out of what is sure to be a treat with something like 100grs of 777 behind a 295gr bullet.[][X(]

Anyone have any other suggestions before I start destroying my stock? I' d like to add maybe 1 to 1.5lbs to the finished rifle weight.

I have the same gun. Yes, it kicks a little more than tar out of you. I havn' t been shooting it in a long while but I am going to put some store bought sand in it. Then cut a thin piece of rubber to seal around the edges and cut to fit. That should take a heck of a lot of kick out of it. That sand should absorbe a lot of the kick before it gets to the shoulder.

suggestion if you want weight go to wal-mart get a can of bondo,that you mix a hardner with its in the paint section but don' t remember the exact name for it,I get the one that says light on the can,mix by directions,it takes about 3/4 can to fill a remington stock.I mix 1/2 of what I need at a time.acording to how much weight I want I take a 3/4 in drill and drill holes length wise in the bondo after it hardens to make it lighter if its to heavy.
If I don' t want to make weight I use pieces of foam and pack it tight inside the stock or a can of great stuff I think its called (its foam in a can,you can get at a building supply)
I have one of the other in all of my hollow stocks.mostly to kill the hollow sound.

Matt-

I would add that some of those spray foam products absorb water. Just be careful choosing a material and making sure that there is a good seal. You wouldn' t want the foam to absorb water and hold it in there.

Just my .02!

I like the sand Idea. It would be like a dead blow hammer at a machine tool shop. Those things don' t even bounce when you hit a big steel mold. I like them, but I don' t want to dink with putting sand in my rifle stock. I would talk to a gunsmith and see if you could get him to do it for you.

I' ve had pretty good success by using expanding foam and a hydraulic bow stabilizer. Adds a nice amount of weight and reduces recoil quite a bit.

I used spray foam insulation and lead balls. Just layer it so they are not all in one spot.

I don' t have an answer for you on this........I would be careful using EXPANDING foam sealants......I' ve seen them push out window frames before.......could split the stocks if not careful.

Doesn' t the extra weight really throw off the balance of the gun?

My muzzle loader was too light in the rear to begin with so the extra weight actually helped balance it. As far as expanding foam splitting the stock, leave the butt plate off and let it dry for a few days then shave off the excess.

Thanks for the replies so far guys........Friz, do you have a brand name of the spray foam you used? I Imagine the foam itself doesn' t add much weight at all.........What did you use for lead balls? Muzzleloading rounds?
I' m just trying to figure weight gain, don' t want to OVER do it.

Not only from a recoil standpoint, this gun can definitely use it for better weight distribution.
Not just being a sissy!
