My 6.5x55 days are behind me (maybe), but back when I thought the sun rose and set out my 1986-vintage M70 Featherweight barrel (oh why dear lord did I ever sell that rifle) I settled on 46grains IMR-4831 and the 129 Hornady spire point. Not a hot load but it served me well for many years in the deer woods and at the range. Bullets were seated out to fill the throat (it was throated like a Swedish Mauser), but still fit in the magazine. I could depend on MOA accuracy whenever and wherever.
