Had a chance to get back out with the .260 today. Bad news is I somehow lost the nut to the strap on my Magnetospeed Chrono so I wasn't able to get any data on today's two loads. Good news is I still had fun and so far every load I've tried has resulted in groups less than 1" at 100 yards.
No signs of over pressure from either 42.5gr or 43.0gr of H4350. The group at 43.0gr is 10 shots.
I'm going to find a nut that will fit my Magnetospeed Chrono and test 42.5, 42.8 and 43.0gr of H4350 right after Christmas. I'm trying to see if I can get 2700 fps with decent SD and ES numbers.
Anyone else got any results to share regarding their .260?
