Sierra Bullets is excited to release load data for four of our newest bullets: the 22 caliber 95 gr HPBT MatchKing #1396, 6.5mm 150 gr HPBT MatchKing #1755, 30 caliber 200 gr HPBT MatchKing #2231, and 30 caliber 230 gr HPBT MatchKing #2251. If you handload for 22-250, 223 Remington, 6.5 x284 Norma, 308 Winchester, or 300 Winchester Magnum check out this new reloading data. Click here to download the data which can be printed and added to the Sierra Bullets 5th Edition Reloading Manual.
NOTE: If you downloaded the 308 Winchester information for the 200 grain bullets prior to February 6, 2018 please replace that information with the corrected information below and in the PDF link above. The 308 Winchester load data listed below will not work for the 200 gr MatchKing #2230 or
200 gr GameKing #2165 as was previously stated.

The comment in red: “NOTE: If you downloaded this information prior to February 6, 2018 the

Are you trying to say that the 308 Winchester load data has been updated, and that information downloaded before Feb 6 should be discarded? Or are you saying you know there is a problem with the data shown currently is known to be wrong, i.e. “ … listed below will not work…” ? Please clarify…

The 150 in the 6.5-284 is great! I run 51.5 gr RE26 with a Fed magnum match primer in a 28″ 8 twist and it stabilized fine.
