Mine was delayed in the mail but finally arrived last week while I was out of town. Just ran home from elk camp to get a couple things done around the house. My barrel weighed in at 18.4oz. Just dropped her in and tossed an arbitrary load of 87 vmax over 24 grains of Tac @ 2.290” and fired 10 break in shots. After zeroing the scope I fired a 5 shot group with the final 5. I was shooting kinda quick off my tailgate off a moving blanket piled up so not the greatest setup. About 2-2.5moa but a couple called fliers. I came home and made one of the fired cases into a comparator case and checked lengths. Looks like I was just over .100” jump for the vmax so I will stretch it out to 2.355” next. I will clean and do a bit more break in, then load development. My Rangecraft and all my other shooting gear is up at elk camp so I will do more extensive testing when we are home for good.
Bullet length followed by OAL to lands
95 nbt 1.120” : to lands 2.430”
95 sst 1.118” : to lands 2.386”
90 nbt 1.072” : to lands 2.415”
87 vmax 1.040” : to lands 2.395”
If anyone has good loads to try with the 87 vmax or preferably the 95 nbt, I am all ears. Finding max charges all over the place on the net. I have most of the good 223 or Grendel powders on hand. My preference would be for something like 8208, Tac, Varget but I also have cfe223, Lever, H335, AR Comp, RL15.5, Stabal match, a little Benchmark and maybe a few others.
