Out of interest what is listed on your ammo section?I have 7mm/284 on my FAC and a very reputable dealer has ordered me a 7mm-08 on the strength of it. I'll put a few thousand rounds through before I decided whether or not to have it re-barreled to 284.
I know someone who shoots very accurately with a 24" barreled .284.
I think the 284 was designed to compete with a 270, but with a short action.
If it’s just 7mm then surely you could go buy 7 mm RM or 7x64?
