I just threw that load together and got 1 moa. I am sure, with a bit more brass prep and TLC I can get sub moa.
I'll go out on a limb and say this is a gamechanger for this cartridge. A specific designed 150 300 blk bullet with a decent BC that expands at around 200 yards assuming a 2100 fps ( or so ) MV. I know what I'll be hunting with 8)

As always, plenty of things to check.

What powders will be best for which barrel length and deliver repeatable accuracy. So far +/- MOA has been pretty easy to achieve from 50-200 yards.

The biggest issue right now is to find the actual BC of the bullet. Speer claims .463, I think that’s wishful thinking. The Berger target 150fb is only .393, Sierra Pro Hunter is .346.

I used .340 to figure drop from 50 to 200 and hit a bit low. More testing will tell.

As time permits I’ll get a better info out here, if there is interest. Rebel is right, in a 16” barrel 200 yards should be no problem.

It would be good to see some others posting some results.

This has my interest. I honestly have not even heard of the bullet. Have to do some research.
Yes, I am a Baptist, and yes I carry a gun. You might think I carry a gun because I don't trust God. Well you would be wrong. I have complete faith in my Lord. It is mankind I have no trust in

Six shots at 50 yards, one inch dot for reference.

Six more shots after .005" seating depth adjustment. Note they are inside the previous six

Good shooting! I am with you on the BC, Speer numbers seem generous. Hopefully I can Labradar a couple shot strings this weekend and get some feedback.
