[QUOTE="Mike D Texas, post: 2674381, member: 71221"] A couple of comments. [LIST=1] [*]What brass are you loading? [*]Have you successfully seated any bullets yet? [*]If you have successfully seated a bullet and all seemed normal, what is the outside dimension of the neck? [*]You will get varying needs of bushings based on the brass you are using because of variance in neck thickness. For example, last night I necked down some ADG 28 Nosler brass to 26 Nosler. The sizing die I have is not a bushing die and “should” fall within SAAMI spec of a 26 Nosler. However it just didn’t even look right so I measured it. The outside diameter of the neck was around .280” which in my experience with 6.5mm cartridges is wayyyyy too small. I started necking back up with mandrels until achieved a comfortable seating tension and remeasured the neck with a loaded round. The outside diameter was .298” which to me indicates a very thick neck. (.298” - .264” = .038” or .019 of neck thickness.) this is much thicker than what I see with most brass at .012-.014”. The point being you need to know the actual neck thickness of your brass and the actual diameter of your bullet to select the proper size bushing. [*]Based on the picture you posted and your second comment above, both are classic signs of excessive neck tension. The ring around the bullet can also be caused by seating into a compressed powder column. [/LIST] [/QUOTE]
