[QUOTE="VinceMule, post: 2697307, member: 122164"] Remember, Wyatt's extended mag boxes for Rem's and perhaps a Bergara, and I put them on all my 700's. Most of the barrel makers are using computer-controlled rifleing methods now. The method of using a tight cleaning brush in the bore, measuring travel over 12" is approximate for several reasons. It is smart to check the twist rate when you get a barrel from a gunsmith to make sure it was not mis-stamped. If you are shooting in ultra-cold conditions, this warrants a fast twist, otherwise, do your twist rate calculations and choose twist accordingly. An increased rate of RPM may be what you want, but on cup and core bullets, higher RPMs may or may not be a good thing as they may shed their jackets quicker AT SHORT RANGE. Higher rpms' may aid in bullet expansion as the distance grows because RPM's do not slow down at the same rate as velocity. [/QUOTE]
