Is anyone running one of these?
If so what loads are you using and seeing for velocity.

Someone on here has one....can't remember who it is though. Maybe check the long range forum?

are you using any on a short action?
my custom 300wsm is using a defiance short action, I've milled a notch in my feed ramp and running terminus mags which give me a max coal of 2.980". really tempted to get a 7/300wsm barrel spun up and try it out as I have 200 cases of new ADG 300wsm brass
