[QUOTE=".284, post: 1070821, member: 19604"] I used PTG but I had them make me a separate throating die so that my smith could set the distance to the lands off of a dummy round. I did basically what Broz suggested by seating a 180 Berger's bearing surface about 50 or 60 thou below the neck and asked for that to touch the lands. This way you can chase the lands as the throat erodes later and still have the bearing surface in the neck as you seat the bullet out further. There is more than enough case capacity to seat the bullet deeper in case if your rifle wants a jump to the lands without crowding the powder. It's a great round. You might consider a barrel with the required twist for Bergers 195's if/when they ever show up. Those will keep up with a 300 grain 338 round with the exception of ft/lbs of energy. For what it's worth I'm getting about 3130fps from a 27 inch tube using H1000. I used nosler brass because I liked the consistency of it but my primers pockets are done after 3 loads so I would recommend starting with something else [/QUOTE]
