Dad was a True Believer and follower of JO'C. He used 60gr of 4831 and 130gr Sierra SBT at least as far back as the early '60s. Many deer died and groups were always small. Dad switched to 130gr partitions and began getting 3 shot cloverleafs.
I use the same load to this day and the rifle still shoots cloverleafs. Year after year. After two owners and over 40 yrs I feel confident load development for that gun is done.
