@BlueDot37,

Good information. Just talked with a fellow at our local gun store who has been reloading for 37 years and he said to try the taper crimp versus the roll crimp. I'm going to order the Hornady taper crimp as there aren't many choices for the 500 for taper crimping. I'm currently using the RCBS 3 die set with a roll crimp. His logic was there's more surface area of the case holding on to the bullet than with a roll crimp. Makes sense.
It appears you have taken it a step further and used the ogive to help hold it in.
The OAL I got of 2.070 from Ranier along with the min/max charges. I just saw a video from Gavintoob that said the Alliant 2400 powder can be used with reduced loads.
Sounds like solid advice.

Thanks!
