I've used both stocks. Honestly, I won;t use a stock from EITHER place again as we have better sources right here in Canada!
That being said, my Richard's experience beat the pants off my Boyd's experience.
Boyd's over-inlets their stocks a few thou so that they can guarantee a drop-fit for any action of a given design. While this is great for the basement gunsmith with low expectations, it sucks ass for the custom gun builder as you end up with unsightly gaping all around the action inlet once assembled. Also, the stocks are finish sanded to 200 grit which again helps the basement dude, but for the custom builder there is not meat left to sand away and get the exact custom shape you want. Also every Boyd's I've ordered had to most uninspired straight plain grained wood I've ever seen. Most of what they sell is black walnut which doesn;t checker as finely as bastogne, circasian or claro walnut.
Richard's customer service is HORRIBLE. Last stock I ordered had to be custom lathed (ie, not a stock pile item). They quoted me 10 weeks to delivery. It actually took 23 weeks! It would have taken longer but I called and harassed them every day for the last three weeks of the wait.
The inletting was true and NOT a 98% press fit as advertised. The bedding was 98%, but hte receiver fit was over-tight and the barrel channel was at least 40 thou under sized. IMHO this is a VERY good thing for the custom builder. It made me fondly remember Fajen who also used to make 'em like this. Pisses off the basement guy but makes the custom builder get a boner. Can you say custom tight fit?
The outside of the stock looks like it was finished by a beaver, but there is ALOT of meat left with which to work with and for my purposes this is a good thing. Also they do inexpensive installation of a pachmayr decelerator which I highly recommend. If you get claro or black walnut spend up to the ebony accents. The rosewood is too light for dark walnut. I'd also recommend considering a 90 degree tip if you get one. This way if you don;t like the stock proportions you can cut it off and set it back on the forestock. Good luck doing this properly with a slant cut...
Richard's has the benefit of offering more imaginative wood. As a minimum I would suggest ordering Select grade A. This is more realistically what Fajuen used to call just plain "select". Expect nice mineral streaking and wavy figure but no crotch feather or fiddleback unless you step up to AA or AAA grade.
Did I mention it's meaty and chewed by a beaver? This is a real custom builder's blank and you'd better have appreciable woodworkign skills if you go this route. Duplicator marks are still present and only some areas have been sanded to around 50 grit or so.
Here in Canada there is at least one stockmaker who will duplicate from a stock blank bedded to your exact action for not alot more money than Richard's Microfit. I'd go that route next time.
Boyd's IMHO, is suitable only for replacement milsurp wood and I will personally NEVER use them again. Their Mauser 98 inletting is truely atrocious, vey gappy. Also their botom metal inletting leaves gaps as large as 1/8" in places which I'm not willing to live with. Too bad you can't order an uninletted shaped blank from them - that would be better than their lathe and pray inletting - yuck! If you get a Remmy 700 blank from Boyd's, I;d suggest ordering an ADL stock and doing the floorplate cut yourself. Seriously.
I still have an "as received" Richard's stock at home that I haven't found time to work on yet. I'll try to get some pics up of it if anyone's interested. It's not pretty when rough, but I can tell it will be a really great stock when done.
