Depends on what you intend to use rifle for.
For hunting, I prefer the 110 long action, staggered feed (older, flat back actions), & wood stocks. Why? Usually can be purchased cheap - $200 to $300. I enlarged the barrel channel for a varmint or light varmint/heavy sporter. Bolt head can be changed, so, build what you wish.
For prairie dog, bench, etc shooting - prefer to build on single shot actions. A little stronger because there is not magwell cut out.
Factory 3 screw triggers can be tuned rather easily to 2 lb if you wish.
The newer right bolt/left port or dual port large shank actions are great to build on as well.
Model 10 actions seem to be harder to find in my area. But for the 223/223 AI cartridges, these work rather well. There are some 110 actions that came from the factory as 223 magwell too. So, don't turn these down as well.
