I am going to start loading 44 magnum. I will be using 2400 and nosler 240g JSP bullets. My question is what's a good crimp diameter to shoot for. In my lyman book it says the neck diameter should be 0.456". My concern is that I want to make sure the crimp is strong enough so the bullets don't back out during recoil. I'm using dillon dies to get a tapered crimp. Thanks in advance.
