Recently acquired sone Federal NT brass. This is the first I have seen of this "NT" brass. The first thing I noticed is that the primers are crimped in. (PITA!) and then I noticed that the flash hole is larger than standard brass. It seems to be about .020 larger than my other brass!
Has anyone loaded any of this before? Does the larger flash hole make a difference in loads? I would think that the larger flash hole would deliver more fire to the powder much faster, and this would effect burn rate and pressure.
I'm just guessing here. Does anyone have any info/data on this brass? Any help would be appreciated.
