Thanks for posting those pictures. Did you find out who actually built the rifle? was it MRC or the guy you bought it from Gun smith?
The magazine box on the left is what I have now in my 375 the follower on the right is what I have now. The follower on your left looked nothing like the original one i got from MRC which they told me was wrong.
7RM,
The box and follower on the left are correct for a 375H&H so what you see in the pic is what you want for your rifle. See the narrow channel on the left follower.....I loaded a 375 in this rifle box and follower and everything seemed fine.....I also had Jeff and Mike from MRC confirm through pics that this was for a 375.
