You can get pretty anal when dealing with taper crimping, I know, I did. Back in my bullseye shooting days every case was trimmed to the same length and every case had the same amount of taper crimp, same bullet weight, same charge, everything.

Of course this made for excellent target loads, but for most folks all this is just a waste of time. Just taper crimp till the bullet is secure in the case and doesn’t move during recoil and you’re OK. Don’t over taper crimp, it will affect head spacing just as roll crimping can do. A little common sense and some trial and error you’ll be OK. It ain’t rocket science.

If you want to play with taper crimp numbers check the case mouth specs on factory ammo or refer to the case mouth measurements in your reloading manuals.
