Fed 215 is what I've been using. I'm going to try the magnum WLR, CCI, and Remington. I think I have some of all of them. It'll be worth it just to see what effect, if any, the primer change has on them.
Ive always used Rem 9 1/2, but that was with IMR4831, I think them 215 are too hot of a primer unless youre trying to ignite more than 80 grains, try a slightly less "hotter' primer like the WLR or even the 9 1/2, and try to seat that VLD .005' from the lands if you can. Good luck.
