I would google the same issue for a Model 70. Procedure will be the same. You will probably have to shorten the ejector blade and the bolt stop as well.The follower should work. I have done this on a Model 70 when going from 7 Rem Mag to 416 Rem.
"after the bullet leaves the barrel it doesn't care what headstamp was on the case" "The 221 Fireball is what the Hornet could have been had it stayed in school"
