Closest would be the Ruger Precision Rifle in .223 with Accurate Mags or MDT 10 rounders I do believe.
Tikka makes a 1-8" twist but mags have to be modded.
.
Another vote for Tikka here, for sure. Get the 1 in 8 twist.
No real reason to modify the mags unless you just feel compelled to shoot 75 grainers.
Lots of truly good deer bullets in the 55-65 grain range that require no mods.
Another one I just bought was a HOWA 1500 Kuiu with a 1 in 8 twist....been very happy with it, but you won't be modifying the mag on it. Accuracy wise I think the Tikka has the edge.
