Thanks again for the comments and feedback. Shot some more rounds on Friday and speed looked good with 59 grains of H4350 using the Magneto Speed. Reloaded another ten rounds and will reshoot for grouping. If it's a good hunting group, I'll call it done. Will give the resurrected FN Mauser from 1966 some exercise in the coming deer season. It was a Cabelas unknown caliber purchase for a low price. They said they thought it a 7X57 and said the owner's relative said it was an 06. I cast the chamber and it's an 06. Would have been happy either way.
