I bought a Ruger American from Short Action Smoker, AKA Whittakers this past summer in 1-8 twist.
It's not magic but it worked for 62gr Barnes TTSX and Superformance powder on Wyo. antelope which is their stated minimum bullet weight for game of that size.
A Tikka 1-8 would be nice but I'm cheap....

Sorry I've not tried heavier bullets, these worked fine.
