284 Win Brass

[StraightPipes]

I just measured some brand new 284 Winchester brass. About .300 from the head (at the web) it measures .493 in diameter.

Can anyone tell me what Lapua (.284 win) measures in this same area? Brand new, unfired Lapua.

My 6.5x284 Lapua cases measure .499 in the web area ........
My Winchester .284 brass measures .494........

Thanks Preacher, I guess my reamer is good to go!
