I shoot a 300 win mag with 180 ttsx and 208 hornadys using imr 7828 during the summer (90 to over 105). No problem because I do load development in July. I live in the valley where deer season runs up to 105.
Buy a Hornady Bullet Comparator set and find the distance on the TTSX bullet touching lands if possible then set it back following Barnes' loading instructions. Like the others mention, no crimp is needed if neck tension is right.
