I'll answer here in lieu of answering both here and our PM conversation.

I have a couple of the Boyd's Featherweight Thumbholes. As I've mentioned to you and in other threads, I have and have had a bunch of Boyds' stocks: thumbholes, "revolution" skeleton baracuda's, prairie Hunters, Pro-Varmint, classics, and Heritages.

The cheekpiece height on the thumbholes is JUST a little low for me with 40mm scopes sitting in medium rings, but that's probably my own problem, as almost all stocks don't have enough cheek rise for me. That probably won't be an issue for you. I do know that their cheek rise is taller than Ruger's standard, I have to add almost a full inch of cheek rise on Ruger stocks to use 44-50mm scopes!

The flat bottomed "flanged" forend on their Featherweight Thumbhole is my favorite profile for aesthetics and feel in my support hand.

Inlet fit for Boyd's stocks tends to be as good as anybody in the industry. All drop-in stocks have the same issues: 1) If they're generous to fit EVERY rifle, they'll be loose on certain smaller actioned rifles, or 2) if they're well fit to smaller action dimensions, they'll be too tight on larger spec actions. Boyd's designs their inlets on the tight side, so if you have a larger spec action, it'll need fitting. Anyone with a piece of sandpaper and two fingers can do that fitting, however, as it's not a highly demanding job. I've had stocks from Stocky's and Richard's Microfit as well, and any of these 3 will usually need SOME small amount of fitting.

In all fairness, if you ever pull your action out and use witness media on factory stocks, it's pretty common that they weren't perfectly fit either, and would require a similar degree of fitting.

You'll be happy with that stock from Boyd's - or rather, your Daughter will!
