[QUOTE="MagMan, post: 272754, member: 966"] Not to be argumentative but I've never noticed any loss of BC or excessive SD with overly spun bullets. Actually I've shot some of my best groups ever (at 1k) with extreme RPM's. My BC's were on par or slightly above Nosler, Sierra and Berger's listings. Also my brother shoots a 300 AX with an 8 twist. It shoots the 240 SMK's spot on to Sierra's BC calculations with no noticeable spin drift, well no more than one could judge at 1K. Another one would be the 6mm-06 shooting the 107 SMK's @ 3400+ in a 8 twist, although I know this is not an extreme case scenario. Still no problems with that out to 1000 yards. [/QUOTE]
