Yes that was my next question. Whether i would need a magnum receiver. I presumed it was the case similar to a magnum bolt face on a bolt action rifle but i was not certain.
I check often. I see that gunsamerica had one a while back but it sold. I was thinking ofbpicking up a no. 1 and rebarreling it. Not sure if that would work.
I have had several over the years including 2 no.1's, a super alaskan 44mag ans a couple of m77's. Currently i am working on customizing a . A ruger african in 300 win. Also i have a m77/44, a 4 inch gp100 and a 22/45 lite. Great guns.
