I have had good results with a 10fp of the same vintage using IMR4895 power and Sierra 52, 53, and 69 MK's, Nosler 50 and 55 BT's and Berger 55 Match. Best accuracy with all of these bullets is around 24-25 gr. of powder. In fact with the lots of IMR4895 I have used, it was necessary to pour the powder slowly down the side of the funnel to allow enough room in the case neck to seat the bullet. I couldn't see much difference in accuracy using the same load in Win, Fed, Rem, or Lake City brass. I tried the Hornady 68 bthp in an AR with 1:9 twist and the results were not good, apparently due to the longer length of the Hornady 68 hpbt.
Results in your rifle may vary.
