Accuracy with Leatherhead 220gr cast and coated out of 300 BO

[Little Creek]

What size 5 shot groups can I expect to see at 100 yards, relative to 220 grain OTM subsonic factory loads? In other words should the Leatherhead bullets be a accurate as the Jacketed bullet loads? I used 10.0 gr of A1680 and loaded to an OAL of 2.05 to eliminate failures of the bolt to close all the way.

Really depends on your optic, barrel length, etc. Go shoot the gun!

Local dude shoots cast in his .300BLK. I don't know if they are home rolled, or what, but they don't come close to matching factory 220 accuracy out of my gun.
