Now that all the pieces to the puzzle are together. I'll be working up 6.5 X 257 loads soon and though it has taken a month of online research ( plus a new computer due to an encryption virus) weeding out the speculates, have found some fairly consistent starting load suggestions albeit still slightly gray since bullets differ. Nonetheless, I feel comfortable to move forward with confidence though maintaining a modicum of respect. After all that, Some have referenced Speer # 8 manual list this particular caliber. Anyone fortunate to have this particular manual and it indeed has this caliber, I would greatly appreciate a readable copy of that particular page/pages. Multiple forums research on this particular manual have both praised it as the holy grail and given admonitions of load data errors due to a variety of mostly speculative reasons from bad copper crush pellets to printing edit errors. With that said, I hold no one liable should a copy of the Speer # 8, 6.5 X 257 load data fall into my hands. (or any other published data you may come across) Thank you kindly Thor P.S. If this had been the WTB section I would have said I would entertain buying a clean reasonable priced copy of the manual however put that out of your mind as this is not the correct location for that solicitation.
