Interesting on the plastic stock comments... I've got about 3 of them that I have not replaced yet. One of them for a buddy in 338 win mag, that will shoot 3 shot groups repeatably under half an inch with the right loads... The other 2 shoot reliably inch size groups. Neither of those is bedded or floated.
While I don't think plastic are the best by far, if bedded and floated out correctly, unless you apply sling tension, then they have always done well enough if searching for MOA basically...
