Im trying too many new components and getting some strange results. Im not sure where to go from here. HBN, Berger 156 EOL, Vihtavuori N565, CCI 250 Mag primers, Norma 6.5x284 brass.
First time trying Hexagonal Boron Nitride. Purchased from Bulletcoatings.com. Followed the instructions to clean the barrel and swab with a mixture of 91% Isopropyl Rubbing Alcohol, tumbled bullets for 2 hours, and cleaned off excess.
Brass annealed, sonic cleaned, dried in food dehydrator then left for several days, full length sized, trimmed, bullets seated .01 off the lands.
I'm not sure what to make of this.
1st shot. 53 grains 2918
2nd shot. 53 grains 2830
3rd shot. 53 grains failed to fire
4th shot. 53.5 grains 2907
5th shot. 54 grains failed to fire
6th shot. 54.5 2894
7th shot. 55 grains 2890
8th shot. 55.5 grains 2882
9th shot. 56 grains 3041 Case had extractor mark and bolt was hard to open
