I am going to do my Rem 300 RUM forend with either the keystock method, or use 2pcs 3/8's S.S. tubing filled with lead shot(one on either side of center). The butt is going to get spray foam, devcon/lead shot mix, to get it to around 10-11 lbs. Heavy enough for long range, light enough for packing/quick shots. Not sure whether I will add extra swivel for Harris or not....any thoughts on that idea?
Hope these links help guys.

I shot my altered tupperware (Remington a way old BDL type mentioned in above post on this thread.

For comparison the previous stock, a highly modified BDL wood stock would hold pretty much 1/4 MOA at 200 yds, my zero distance.

I bore sighted on Molly's Nipple, a land mark about 5 miles away. This ususally gets me on the 8 1/2 X 11 target paper.

The Cartridge is a 338 RUM w/300 gr SMKs w/101gr US-869. Also a Holland brake is installed.

I fired the first shot. The scope never left the target backer 4'x4'. But there was a helluva smack to my shoulder that I wasn't expecting. Instead of about like an unbraked 270 Win w/ 140s it was more like an unbraked '06 w/a good hot 165 gr load.

It wasn't a push through recoil but a smack and release type of thing. In a tee shirt it kind of hurt but not for very long and this evening there is no ache or pain.

I think the difference is the two bit REM recoil pad which is as hard as a rock and of a small profile. The previous stock had a grind to fit Limbsaver what was full size at the but and tapered to the stock. Looked funny but sure felt good. I'll go that route on this one also.

The intent was to determine if the tupperware stock shot well enough to do the final paint job. The paint job is worth about 10X the value of the stock.

After the bore site job the first shot went off the paper in the bottom left of the target. I covered with a black sticky.

I then adjusted 2.7 MOA up and 2.5 MOA to the right.

The second shot showed that the right adjustment was spot on.

The up adjustment was almost twice what it was supposed to be. Hmmmmm?

I then adjusted down almost 1/2 of what I had just gone up for the third shot.

The third shot was as they say "dead nuts" whatever that means

Not a group but good enough to shot that the stock shoots. It's also quicker to get on target. When snap pointed on flying birds the bird is always in the scope. Usually more towards the center.

Also it shot well enough to determine that Scope windage adjustment are as advertised 1/8 MOA but the elevation is somewhere around 0.2

The elevation clicks won't hurt as the mil dots are spot on and in the first focal plane.

If the new bullets I'm experimenting with even come close to expectations with a 300 yd zero drop at 1K will be right at 5 Mils. Which suits me.

Stock modification details:

Hawg'd out the recoil lug to fit the 1/4" thick recoil lug then epoxied it fully.

All other modification were to the outside. Modified the comb. Added a palm swell and did away with the checkering.

I'll post pics when painted.

Roy I used a plastic welding fit from Eastwood and I welded in 2 aluminum round stock pillars in a sps varmint stock and then drilled holes where the action sits and used epoxy to bed the action. I shoots 1/2 moa all day long until it fouls.

I spent a few hours building my bipod for the 338 RUM and tupperware stock.

Previous shots from a pedestal rest show things were plenty solid.

Then, I mounted the bipod. The vertical flex in the forearm was about as expected.

HOWEVER, the twist is astronomical and was totally unexpected!!!! Almost a deal breaker but overcoming challenges is the name of the game.

The flex appears to begin a the front of hte recoil lug which is a heavy duty Holland lug about 1/4" thick.

If my remarks regarding excessive flex regarding B&C Carbalite stocks I appologize and retract any negative vibes I may have sent.

Linksmechanic, there is an SPS stock on the way

Any recommendations to improve a Sako Finnlight stock?

MTRman:

Post a pic of the stock from showing the inletting and barrel channel.

I'm sure I have recommendations that I haven't even thought of yet.


I took some pics of what I did to my Rem tupperware stock and will post when I arount tuit but shortly.

Weather's nice to day going to to some shooting and playing with grandkids

I lost my digital camera last year on a backpacking trip and haven't replaced it yet. As soon as I get my NF scope paid for I'll get a new camera The forearm is hollowed out like a tough. I was reading another thread about possibly setting in a steel rod or carbon shafts in the forearm in the bedding material. Also wonder about injecting expandable foam in the hollow area behind the pistol grip? Any thoughts on that?
