It’s a 458 in a lever action. Mine was a rebarrel with a full length magazine tube. Nicely done but never figured out who did it. Restocked as well. 400 grain bullet won’t stay in elk no matter what angle you hit them at.
I sold it as my neck cannot handle much recoil any longer. Made me sad and I miss it. I shot from collar button bullets to 500 grain mastodon mashers. Excellent cartridge in an excellent rifle.
