I know that I read in a previous post how to convert the magazine in a long action for use with a short action cartridge. What I have is a model 111 that was a 270. I would like to change over to a 7mm-08 for my 10 year old son.

Do I just need to change out the follower. I have changed out long to long and to RUM but have not yet changed long to short.
Thank you all for your experience.
