Could I rechamber a 26" 7 mag barrel to a 7 lrm ?
The barrel of your rifle would have to be setback a little but everything else should work such as your magazine and boltface/extactor. I am sure this is very doable for a qualified smith IF the chamber reamer is readily available. The 7LRM is the creation of Gunwerks Inc. and they might consider it a proprietary cartridge. You would only gain 4 grains of powder capacity and I really don't think the velocity gain would be worth the expense and bother. Every cartridge that would give you a larger gain in performance would require magazine lengthening, but the 7STW or the 7-300Wby wouldn't require any barrel setback. Hope this helps.
thanx for the info. any suggestions?
What can I rechamber it to if I bought a 7mag barrl or even a 7wsm barrel?
