6UM vs 22CM

[rbutcher1234]

My goal is to have an identical tikka to my 223, except with greater terminal range. I reload, so that’s not an issue. I would be looking for a barrel between 16”-18” and suppressed with my TBAC Dominus cb. My existing tikka is a 20”, but I would like to move shorter since moving up in cartridge horsepower will afford me that.

Which one of these would be better suited for extending my terminal range? Barrel life is not an issue for me. I use my tikka and self limit to 450 yard shots and under due to velocity. I have hunted with my 300NM out significantly further, but those were very focused situations. I have minimal interest in packing my AI up and down western mountains.

Pros of the 6UM: mainly not limited by states who restrict big game hunting to bullets .24 and higher

Pros of the 22cm: less recoil and better spotting of shots from all positions.

I generally shoot 10k shots a year in just center fire rifle, with a large majority from field positions. I’m interested in the technical comparison of these cartridges. I have played around in JBM and compared to cartridges I am familiar with shooting (5.56, 308, 300NM, 6BR), but I am interested in real world experience from people who have used either or both of these.

Cant comment but have been debating similar rounds for similar reasons so curious to see what others have to say.

With a muzzle device, I’d go fast 6mm. The recoil is plenty manageable.

Either option would be 100% suppressed with my TBAC Dominus cb (~6.3” suppressor). Tbac confirms that 16” barrel with the 6UM is good to go, so all options are open.
