Just getting my first 300WM going, getting ready to order my dies and my question has to do with whether or not to taper crimp hand loads? It will be my first time reloading this cartridge, thanks for your input.
I generally don't crimp... unless I am planning on the ammo getting beat up. Load up a few rounds and run them through the gun without firing-- the same way that you will run the bolt the rest of the time. Measure OAL before and after- and see if you need a crimp. One of my guns will seat the bullet deeper if I run the bolt hard with no crimp- so I use a crimp as a band-aid instead of actually fixing the issue.
I haven't had better accuracy or consistency with a crimp but many people say they do.
