the worst 458 i ever had was an interarms whitworth. very good looking but only 8# and skinny stock. i couldn't shoot it and i'm not recoil shy. it split the stock on the 3rd round. i added 1.5# lead front and back and glued it back together.
next one was a post 64 m70 which had 22" bbl and only went 8.25#. but the stock was much better and it wasn't unpleasant at all but i agree they need more weight - like 9.5# or so. and 7#-11oz makes my blood run cold. no to mention that, for that weight, the stock must have some pretty low density wood and i'd have concerns about it holding up.
i bought a really good looking stock for a cz 416 rigby and it feels about like balsa. would look fantastic when finished out but i'm afraid it wouldn't hold up under the load.
