I've trued a bunch of 700s over the past 20yrs - quite a few for myself, the rest for customers. But when custom clone actions became available for under $900, my attitude changed. The last bare 700 action I bought sat in the safe for about 3yrs, and by the time I'd made up my mind what I was going to build on it, Remington had gone tits-up, and I couldn't even find the bolt stop or sping.
I'd ordered in a custom bolt with a 223 boltface, spec'd body dia at .700", mini 16 extractor, and .061" firing pin hole, so bought a complete striker assembly for it. The lack of a bolt stop was still an issue, but when I found that LRI had developed their own custom bolt stop, I decided to take the easy way out and just send the action to Chad.
While I was talking with the LRI sales person on the phone, I asked about dealer pricing for the full action truing and bolt fitting - I'd watched the video online of Chad's new 5-axis machine doing the whole job, and was fascinated with it. Since I had pretty well decided that this was going to be the last 700 action for myself, I decided why not have them do the truing, as well as fitting the custom bolt (after spiral fluting it)? So when the action came back, I spent a good deal of time just enjoying looking at it, and all the work they'd done to it. Yes, the custom side-mounted bolt stop works pretty slick & looks at least as nice as any I've seen on many different custom actions. But they also asked if I was going to CeraKote the action & bolt while taking the order for the work, so they could adjust the bolt bore of the action to make sure it would work well with the coating. And after I'd gotten the bbl done for it, and then CeraKoted the complete bbl'd action with Armor Black, it ran very slick. So now, it's one of my favorite rifles, with a 1-9tw Bartlein 20cal bbl that I chambered in 20 Tactical, in a McMillan Game Scout stock in McWoody gel coat finish. This was more-or-less a special rifle that I put together for myself, and I had a great time placing the order for the machine work on the action & bolt, as well as a great time admiring that machine work when it came back - just a treat for myself, with no need to justify spending as much on it as if I'd bought a Zermatt Origin instead (which is what I did the next time I did a rifle project for myself).
And today, if a customer walked in with a request for a rifle build, I'd definitely recommend a custom action. And if the guy (or gal) had a 700 action that he or she wanted to build the rifle on, I'd just tell them that it was going to be sent off to LRI for most of the work, and that it was going to wind up costing them as much as an Origin or other 700 clone. Of course, they can always decide just to have me put a custom barrel on the action without truing it....
