Can someone help me? I have been told that this is the best firearms forum on the internet. I live in the UK and have an extremely healthy interest in ballistics but because of my location I do not have a great deal of access to actual firearms. As a result, I feel that I may be missing some vital experience that is making it impossible for me to resolve a problem that has been bothering me for some time.
Recently I have been intrigued by the 8.6 Creedmoor calibre based upon a modified 6.5 Creedmoor cartridge case with a .338 calibre projectile.
Now having researched some other 'similar' large bore subsonic calibres I found the .338 Whisper cartridge that came in two versions, one based upon the .221 fireball and the other based upon the 7mm BR.
So here is my question. According to all the information I have been able to find, both the 8.6 Creedmoor AND the 7mm BR (Whisper #1) cartridges require an AR-10 platform with a .308 bolt face and a .338 calibre barrel.
So assuming that I had an AR-10 with the .308 bolt face and a .338 barrel conversion, would that rifle fire BOTH 8.6 Creedmoor AND Whisper .338?
