[bruno]

was prepping brass today, and then read an article in precision rifles on here. the article said win brass was not uniform in the flash hole, well i noticed that today. what size drill would you use to clean a flash hole in a 270?

I use a #46 .081" drill bit on my .270 cases.

RCBS and Lyman make flashhole deburring tools.

I use the RCBS, a bit of a pain to set up, but great to use.

RCBS PN 8810? depending on caliber, with bushings for other calibers.

Lyman PN 7777760.
