new Lapua brass, CCI 450's, BL-C2, 107gr SMK 2.245 COAL. They chamber just fine and extracted cleanly (unfired, just testing feed from mag). The feed ramps appear to put a neato little scratch in the bullet nose upon feeding but not real concerned about that. Ran them up in .2gn increments from 28gn.
The best thing about loading them so far has been the ball powder. Stick powder I use on all my other rifles throws inconsistently as hell and jams up my thrower but this ball powder with the small grain size was throwing perfectly each time. I double weigh each charge (digital then beam) and saved a lot of time with the ability to accurately throw charges and not have to add or remove some each time.
Nothing anyone hasn't seen before:
These won't be running super duper fast but they're just work up loads. I've got some 100gn A-max's waiting for me at home and I'll put 12 of those together with the same charges and COAL's tonight. Hopefully I'll get a chance to hit the range this weekend and see if we have a nice 1-hole load. I found the perfect load for my 6x45 and 5.56 on the first runs through load development. Doubt I'll get the hat trick with the grendel. Besides.. I'm hoping I can run just a little faster and still get the groups under .5".
