Official Grendel SBR/Pistol Velocity Thread

[LRRPF52]

We've gained a lot of data on 16-28" Grendel muzzle velocities commonly-encountered by the horde over the years.

I'd like to start a dedicated thread where we can reference recorded velocities of the shorter barrel speeds.

I'll kick it off with the format and my personal experience so far with my Faxon Group Buy 12" 5REE barrel. Let's try to keep it populated with mv data rather than discussions, so that it will be easy to reference without having to sift through posts other than data.

I know there are a bunch of you out there with 10.5"-14.5" data that many would love to see to get an idea of what to expect. I'll do the next post showing hand load format, which I plan to do next with my 12".
