Folks,
I've got a 20" 1-7.7 twist VARMATCH barrel ,I guess it's closer to 8 twist than 7 .

I'm wondering if any of youall are shooting this bullet in an AR 15 platform.

Hornady " suggests " a col of 2.380 or 2.390 if don't recall which but it's a long overall length . I'm wondering if anybody has loaded them shorter and how it worked out .
I can understand their reason it's ogive is way back . Maybe you guys know of a different kind of mag or a modification. I appreciate any pros / cons you can pass my way.

Thank you in advance for your time and help.
