I am working up a load for a Jan Mule deer hunt in Mexico. The rifle is a 300WM lightweight Beanland custom with a 10 twist Lilja, topped with a 2.5-10-42 NXS. It shoots 168 Bergers very well, and I have taken two nice whitetails with this bullet. Have been working up loads using 168 Barnes TTSK. They also shoot very well, but am having difficulty getting the bullets to seat deep enough using a full charge of H1000. Any other thoughts on a great bullet, thinking 6-700 yards for max range with this gun.
