I bought a factory Winchester H&H length mag box and follower so that I could seat 210 Bergers out to the lands in my 300WM. You will have to modify the ejector so that the case on the LH side of the mag can rise high enough to be caught by the bolt. Also there will likely be some minor work...
I know that someone here will know the answer to this but I couldn't find anything with the search function.
I have a 300WM on a M70 action. I've gone to a full-length mag box and follower to take advantage of the length of the 210 Berger and 208 AMax and to seat them out to the lands. What...
