I haven't done one with the Howa actions from Brownell's, but I have with Rem 700 actions from Brownells and ptg, a cz action from Brownells, and savage actions straight from savage.
Just like an AR, I don't end up saving myself any money, but I get exactly what I want, and I enjoy the journey in putting them together.
I have been on the verge of ordering one of the Howa's for some time now, just can't bring myself to order one over buying more 700's.
Boyd's stocks are fantastic for the money. I typically end up blocking and bedding, so I don't mind the little work they usually need for fitting. I have a dozen or so of them in the safe currently, and 4 others awaiting bedding onto their new actions. As an example of the work typical of a Boyd's stock, my most recent was a Ruger M77 MKII, needed to be nudged over about a 1/32" to center in the action inlet and barrel channel, which was easily corrected when I installed the pillars. I had to route the trigger guard inlet a little deeper and the overall stock was a little shallow so I had to file the mag box a touch to get a nice flush fit of the mag plate at the belly. Took a few hours, but as they say, "weren't no hill for a high stepper."
I wish their adjustable cheek risers used an elevator nut instead of the expanding trunions, but it works. I formed a piece of delrin into a dead-stop block, pinning it under the cheekpiece to let me be assured it wouldn't fall in the middle of a match. Pull the cheekpiece and pull the block and I can move down if wanted, but only if I so desire.
