I have a 6.5 mm gain twist ready to pick up from Ron Smith. It's 1:14 to 1:8. I wasn't hoping for much velocity gain. Although it would be nice. I got the gain twist for lower initial pressure spike.
That being said I was always curious about gain twist spinning the bullet faster than the final twist ratio due to the 'gain' it's getting as it travels down the barrel.
