So are you saying a 6AI is more accurate than a Dasher?
That is not at all what was said. I very clearly stated that the 6mm AI IS A BETTER CHOICE FOR EXTREME LONG RANGE HUNTING AND VARMINT HUNING IN THE FIELD!
But I will say my last 6mm AI more than once proved it was capable of less than 1/4 moa out to 300 yards. But barrel life would be very short if one was to shoot 54 grains of powder 10 to 15 times in 7 minute courses of fire. Not to mention the repeated difference in recoil.
One reason i would not recamend it. Would it compete with a Dasher at that range, absoluetly! In PRS and F -class where good enough is what is neaded for clean scores!
I also made it clear! For absolute accuracy, which is neaded to win in group shooting,,, the 6BR and the 6BRA have proven more capable! The records prove that!
I also clearly stated for PRS or F-class competition the Dasher may be a better choice.
But the big issue with the 6mm AI in this kind of competition is the volume of powder and number of shots in short time periods, where hits are all that are requiered.
But using a slower twist barrel, where 75 to 95 grain bullets can be pushed over 3600 to 3800 fps, and still be effective terminally on Varmint, or medium game, yes, the 6MM AI is a superior choice, as i stated in the field, and far superior to a Dasher for these duties!
For absolute accuracy at 600 yards the 6BR was a better choice.

But even a Dasher could have won high score easily in this same match. But a Dasher has never turned in a group like this at 600 yards. He'll my 6MM AI could shoot a 50 score with one or 2 X's, even my 6ppc. But neither will group that good at that range.
Finally, these are just some of the reasons I stated clearly,,, NO ONE CARTRIDGE WILL EVER BE BEST FOR EVERYTHING!
