Myself and my gunsmith checked, both of us came up with 2 turns in 24”. First 243 I ever saw with that twist, but then again it is a Varminter. You never know what Ruger will put out.
One of the rifles I regret ever sending down the road was a 77V tanger in .25-06 that I bought new in 1974. I always wondered if it had a somewhat slow twist barrel but don't recall ever checking it. I never could get decent accuracy with 100 grain bullets but 75 grain Sierra flat-based hollow points would shoot between 1/2" and 3/4" with IMR3031 or IMR 4064. Eventually I decided it was overkill for shooting woodchucks (but a lot of fun) and sent it down the road, keeping my 77V .220 Swift that I still have.
