Randy was kind enough to make up some .673 long .22's to test out of my Sako A1 22PPC. With a measured 14 barrel twist, the math on the default BR 52 gr. bullet doesn't hold up for stability. Randy's 52's are killer good in a 13 twist, by the way.
Yes, it's a sample of one. Certainly not a real-deal BR rig by any stretch of the imagination and it's got a factory barrel and chamber to boot. It does make me wonder how many 'tuning' issues with the PPC's are really bullet length/twist rate issues. If they can shoot this well in an tuned up factory gun...sheesh.
