To all you smart people here, riddle me this:

So, partly for reasons I expressed here: https://www.24hourcampfire.com/ubbt...ly-hendershots-specifically#Post15827400, I ordered some Hendershot’s 6.5-300 ammo loaded with 127gr LRXs, supposedly at roughly the same muzzle velocity as Wby (3,500 fps). I’ll see about that tomorrow.

The Hendershot’s cartridges, like the one on the left below, have the bullets seated just a bit further out than the Wby-loaded 127s.

However, the Wby-loaded bullets, like the one on the right, have a ring cut into them just forward of the case neck. This is peculiar to me for a couple of reasons. One, the HS-loaded bullets don’t have that ring forward of the cases, and you can see a bit more of the bullets on the HS ammo.

Second, the Barnes website pic of that specific 6.5 mm bullet shows the most forward ring, I think, further back than the ones on the Wby-loaded bullet:

What gives? Did Wby modify the 127gr LRX bullets before loading them? Or is something else going on?

Thanks in advance for any answers.
