Rem 700 Police 300 Win Mag reloading

[Dan Rehling]

I have just broken in the barrel and am reloading with winchester brass, winchester large rifle for mag primers, 210 gr Berger and trying 208 gn A-max Hornady. I have been loading with H-1000 at 72.5 gr.
I am going to step it up a bit to 79gr H-1000.
any advise from experienced reloaders with these componets

Sometimes with belted magnums the sizing dies do not get all the way down to the belt . This can cause chambering issues. If you experience that problem then buy this die Belted Magnum Collet Resizing Die Innovative Technologies - Reloading Equipment
