6.5-284 reamer

[bryan]

I was given a Littleton action several years ago by the SA F-class team and recently had the barrel set back. The reamer used was a .294 neck. Is that standard, or do I need to trim the necks?
I'm new to the 6.5-284.
Thanks

Bryan,

My most recent Lapua 6.5-284 brass unturned has neck thickness of 0.0145. Add twice that to .264 and you get .293. I'm fairly sure the standard chamber neck size is .296, which makes sense. So in answer to your question, you'll need a very light neck turn.
