Re: who can and want to guide me in reloading
Get a good manual from one of the manufacturers of the bullets you plan to use. You can also find some pretty good info on Hogden, IMR, Winchester powders on their site. Hornady prints their manual yearly as a magazine, and it's very up-to-date and pretty complete.
Get the instructions for your Forster dies, read them, and then set them up on your press - by the way, I'm jealous, I've wanted a Co-Axial for several years and couldn't find one available when the funds were.
I haven't shoot that much Lapua brass, and I do make it a practice to FL size and trim (or at least check the OAL of the brass) on all new brass. Just the way I am.
Drop me a PM if I can help.
Welcome to the madness.
