A 300 rum is a .308 dia. bore and a 7mm allen mag is a .284 dia bore so no you couldnt but you could order a new .284 dia barrel and have it chambered to a 7mm allen mag.

Re: 7mm am

They claim that the action isn't strong enough becouse tge Allen mag is based off of the lapua case, but Remington makes a factory gun in the lapua round so go figure. Kirby Allen is the man to ask goes by fiftydriver on here.

Re: 7mm am

I'd kinda shy away from that idea.

Run it by Kirby though as that's the only way your gonna get a 7mm AM.

Re: 7mm am

I copied this from Kirby's post on myths of overbore cartidges. It's his personal hunting rifle

7mm Allen Magnum
160 gr Accubond @ 3414 fps
Rem 700
Lilja #3 SS 1-9, 26.5" Finish length
DE 1/2" brake
HS Precision sporter stock, green with black web
HS Precision DM system
Tuned Rem 700 trigger
Leupold Mk4 FFP 3.5-10x 40mm w/ TMR reticle
Anything packing rifle
Weight: 10.0 lbs ready to hunt with

He goes on to say somewhere that its better to use a custom action because they have much tighter tollerances and can be taken to higher pressures. So this would lead me to believe to take full advantage of the AM use a custom action. He does state that he doesnt feel the need to take his rifle as hot as others do though. It would be best to ask him though. I know that he isnt building rifles off of anything but custom actions anymore, trueing the rems slowed him down to much, so Im not sure if its even possible unless you have it done somewhere else and then to him to have it chambered. Also since you cant take it to its full potential in the rem action Im not sure if its really anybetter than the 7 RUM in that action. Again goo dquestion for Kirby
