I recently finished building a custom Mauser in 22-250 remington with a barrel twist of 1 in 8". I want to try the custom competition 69 and 80 grain bullets in this gun. Anyone know where I can find data for these bullets in 22-250? Love Nosler's reloading #5, but it has no data for these bullets and the website doesn't show any data for 22-250 for these bullets either. Most 22-250 have a twist rate that is much too slow for these bullets, I guess that's why they haven't shown any data on it, but any help anyone could give would be appreciated. :?
