I've been considering rebarreling my Rem. 700 30-06 with a Ron Smith gain twist bbrl. Claims are that you will gain another 100-150 fps. and that the bbrl. will be more forgiving of bullet weight, ie. give decent accuracy with a broader range of bullet wts. Anybody have first hand experience with gain twist bbrls., and Ron's in particular? If the claims are true, my old '06 would be right up there with factory 300 WSM
