.284 Shehane Reamers

[Kyle Schultz]

I understand there are basically two .284 Shehane reamer designs out there. Each spec'd differently because of differences between Lapua and Winchester case webs. Can someone please educate me as how to differentiate between the two reamers. Thanks!

I'll answer my own question thanks to Jim Hardy.

A reamer designed to work with Lapua brass will have a case web diameter of 0.50??. For instance, the reamer shown in the 7mm Cartidge Guide has a web diameter of 0.5029". Another reamer drawing I have indicates 0.5019".

A reamer designed for Winchester brass will have a smaller web diameter; something on the order of 0.49??.
