I'm having a problems trying to work up a load for 100gr Barnes TTSX. I have imr 4831 and 7828 powders, and worked up a load of 68gr of imr 4831 and 100gr TSX with an oal of 3.167 that shoots 3/4" moa, and a load with 69gr of 7828 and 110gr nosler accubond set at 3.250 oal that shoots 3/8" moa. I can't seem to find a load for the TTSX that will shoot under 1-1/2" moa. I'm shooting a wby Accumark. Any help would be appreciated. Thanks in advance.
