Sir Jerry, I made a "Rooster Note" on how to please "Mama Chicken": Build her a 30x35 foot boma with concrete patio. Quite the Valentine there.
Sir Spruce, I have made the Boyd's and Richards Micro-Fit laminates work on harder kickers than the MIGHTY .458 WINCHESTER MAGNUM. Not much difference in those two laminates, I reckon. They are still just wood between the epoxy gluing. They can crack along the wood laminations.
One was reinforced every-which-way after a crack developed at the tang on a .460 Wby. It lived on after a re-barreling to 470 Mbogo.
The other was used on a .500 Mbogo, reinforced at the start, no cracks yet. They can gain a pound with all the embedded steel allthread and epoxy in 3-D inside the stock. Can be slim but heavy.
I much prefer the B&C Medalist type stock as Sir Larry suggests. They weigh only 2.0 to 2.5 pounds for M70/M77 to CZ 550 Magnum, With the bedding block, no barrel lug is needed on a .458 WinMag, or any other man-portable piece.
Thank you Sir Ron . I got too sleepy to intelligently reply to Sir Larry last night. I will see if I can lay hands on one. The Spruce King has a big underbarrel recoil lug silver soldered well forward . Iirc around 12" in front of the receiver ring . But I'm sure some judicious use of a dremil tool can open a hole to fit it into.
