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.
