I realize that a low sd is not always necessary for accuracy at short to mid range but it bugs me to see a high sd. My load for my 204 is 27.0 grs of H4895 39bk and 7 1/2 primers. This load shoots tight moa but my sd is 41! In my Dasher and my Creedmoor I keep my sd under 10. Im using a Magneeto and Im thinking its giving me good readings. Id love to try a radar but no chances yet.
