My pet load for all my .30'06's is 43 gr. H4895 and I use mainly Sierra 168 gr BTHP's for match shooting where handloads are permitted, 165 gr. bullets for deer hunting, and pulled USGI 173 gr. match bullets for informal target/3 gun/turkeys; they all shoot to the same POI. I'm not a very good benchrest shooter but my SC 03A3 with Leupold 3-9X and rebarrelled with '44 Remington 2 grove barrel $3 DCM barrel will shoot all of these loads to ~ 1 MOA accuracy. A three round triangularization group for a check before going hunting often yields a group well under 1" at 100 yds. This is a mild load and yields good results with my M-1's and all of my '03's. HOWEVER, before using anyone's loading data you should double check your own books and have professional instruction; I offer this data without accepting any liability for its use or misuse. If there is anything wrong with my load, it is that it might not be stiff enough to work some M-1s with tough op rod springs. The original 6 groove barrel on the SC sporter was ringed, but gave fair to good results with 180 flat base bullets - I can't remember the charge but it was mild as I recall. It didn't like anything lighter.
