I'd definitely use the same practices as a trigger job. Slow and steady, checking often. I don't feel the need to use large pillars, really. I'll be doing a full bed job at the same time, so the action will have 100% support under it. The only thing the pillars do is keep the stock from compressing at all and make sure it's the same every time it's torqued down. The ones I used on the Axis' I've done were fairly small and work great so far. Thinking I'm leaning towards notching the sear at this point unless someone has good input why I shouldn't.
