Half inch, 155 Mega over 46.5 H-4831 (surplus powder I bought in the ‘60’s) at around 2,500 FPS. I understand this old powder may be a tad slower than current production H-4831. It smells like new powder, no dust. It performs very well.
I shot quarter and 1/3 MOA groups with 139 Scenar over 47.2 MRP at around 2,650 FPS. 45 gr RL-17 was almost as accurate, still sub MOA, and faster at 2,749.
Those two bullets are the champs in this gun. It’s more finicky than my Shilen 6.5 Creedmoor. But does very well when fed what it likes.
The CM shoots a larger variety of combos sub MOA. The Swede shoots everything under 1.5”, but to a Loony, that’s not Kosher.
The CM likes the new 147 ELD-M, haven’t tried it in the Swede. I hear good reports on terminal performance with that bullet at Swede/Creed speed.
