Components are listed in loading manuals mainly so you know exactly what produced their results. Primers may be slightly different, cases may have slightly varying capacities, etc. As long as you start at the starting load for the given bullet style (jacketed or lead) and bullet weight, you should not have any problems using any component for that cartridge. The only thing your really need to know is the size of the primer. Here's a primer
cross reference chart in case you're not familiar with a particular brand's naming system.
Do NOT reduce the powder charge below the starting load regardless of primer brand. Quite frankly, in over 30 years of reloading, I've never found that the brand of primer had any significant effect on velocity or accuracy. The only caveat I'd throw out has to do with the Remington 6 1/2 small rifle primer. I don't use many Remington primers (use CCI almost exclusively), but according to what's posted in the description on Midway's web site:
Considering the cost of bench rest primers, I'd just switch to a different brand.
I can't speak for anyone else's experience with the 30-30, but from my experience I would strongly suggest that you get a
Lee Factory Crimp Die for it. The 30-30 is what caused me to buy my first Lee FCD. I was having fits trying to get enough crimp to hold the bullet and not bulge the case. I was about to relegate the 30-30 to factory ammo until I discovered the Lee FCD. I now have one for virtually every caliber I load.
