Just did this with a 16" barrel. Gun has a grey birch chassis and I can zip my backpack up around the gun when its folded.

Its a proof steel barrel. Im at 2600 FPS with the 147 ELDM in the white box factory ammo. Shot 2 with my buddies handloads for his 6.5 PRC and I was at 2800 with the 147. I'm very happy with that speed.

Yikes, 60 grs of H1000 sounds way beyond max. Gotta be a very compressed load. Your brass will be toast after one firing most likely.
