So have you actually shot a 105 Scenar in a 9 or 10 twist 6BR?
In my 8.5 twist 6BR they shot great at 500yds, but at 1000 went all vertical because they were losing stability. More speed or more twist would have fixed the vertical.

This thread concerns loads for the 6mmBR Norma ONLY. I have deleted posts that deal with other chamberings. We do not want to confuse readers who turn to this thread for suggested loads for their 6BR.
Anyone wishing to discuss loads for other chamberings can do so elsewhere in the Forum

Sorry, I work for a defense contractor and breathe acronyms.
"ITL" is intended to mean "in the lands". I typically use ten thousandths (.010") jam into the lands with Sierra bullets. Oddly, Bergers do not seem to do well at that setting and I shoot them back .01 to .02 from the lands.
