Wow, 450 that's a great looking rifle. Thanks for posting the pictures and info. If mine comes out half as nice I'll be thrilled. I haven't obtained a barrel yet, and had the same concerns about twist. I was thinking along the lines of 1:66 or 1:60.

I think the modern fast twist barrels are designed with sabots in mind, not us luddites launching big hunks of lead. Your's certainly seems to not have any issues with twist based on those groups!
