Thank you sir! Interesting results on my end. No noticable pressure signs. But those velocities?! savage model 111.

That looks like it's a pretty warm load.

yeah, i am not sure where to go with this 1. cases, pockets, all seems good, easy exctraction etc. just the velocity.. same chrono a 300wsm with 180sciroccos was right at 2950ish where i figured it should be.
