243 Win 16” Velocities?

[24valve]

@Small-foot's 243 is cut 17", suppressed, and shooting 95 TMK's at 2760. My 18" 243 shoots the same load at 2800 fps.

@ztc92 has one cut to 16.5" and could share some velocities

I’m getting 2835 out of a 17” tikka with 95TMKs and Varget

Are you near max with that load?

Im at max with H4350. I’m using PPU brass as that’s what was available and I’m hitting pressure around 39grains. Seems like people using star line are closer to 41-42gr.

16.5” tikka suppressed. 41 gr 4350 108 eldm’s. 2693 avg, but I’ve only got maybe 75 rounds through it so should speed up some.

41.2 h4350 averaged 2805 with great es/sd but showed an ejector mark every 3rd round or so - right on the edge for me.
