Seating Depth Help Pls

[lukehalee]

In a 6BR with Seirra 75g Varmint bullets I have no problem finding my rifling marks on the bullets. I can set my Bart's 68g Ultra's at the same depth using my Sinclair nut and find nothing. I have tried sanding them with 1000, machinist blueing, and black markers, still nothing. I can seat by Seirra's .030 in the lands, set the Bart's up the same and all I get is 1 faint mark that is in the right place to be a land but nothing else.

Any ideas?

Thanks,

Mark
