My new Magnetospeed chrono arrived today so I had to go check it out. It's worth noting that the chamber was quite toasty for much of this so any rounds sitting in it any length were very hot. Very handy chrono for shooting at an indoor range. Based on the tests done by Brian Litz, it is as accurate as they come.
I think the AB has potential. One primer in each looked kind of flat. Not sure what happened. The chamber was hot, and I did sit there for a bit fiddling with the sight picture on a few shots, so those would have been quite hot. But a solid 2650 with a 200 AB, with a very temperature resistant powder, is something to like. Also one of the 47gn TAC primers was rather flat. Odd.
Also did these: 200 Trophy Bonded Tip (Factory): 2645, 2640 200 Trophy Copper (Factory): 2556, 2547 210 Partition (50 LVR, BR2): 2567, 2571 200 Hot Cor (52 2000MR, BR2): 2573 200 SST (52 2000MR, BR2): 2642 185 TTSX (48.5 TAC, BR2): 2748, 2738 185 TTSX (48 8208, BR2): 2742 160 TTSX (52 AA2230, BR2): 3071, 3063, 3056, 3075 (there are no visible signs of pressure at all) 180 BT (48.5 TAC, BR2): 2781, 2790 200 Hot Cor (52 LVR, BR2): 2662, 2698, 2666 (middle one sat in a rather hot chamber for a bit)
