I suggest you spend some time reading a good instruction reloading manual, Speer, Hornady, ABC's, and Lyman is especially informative if you ever decide to load lead also. But for the basics of loading jacketed, I like Speer, as they really lay it out in an organized step by step manner.

Primers- which brand or even type, be it Winchester CCI, or Federal, magnum or standard, is really only pertinent during load development. I have a brand / type I prefer, my neighbor may prefer another brand or type, but at the end of the day, as long as we work the load up with that primer and re-work each time we change brand or type this and accuracy is all that matters. I've been using CCI and Winchester for about 4 decades, haven't had a single misfire yet. BTW, you can use a magnum primer for a standard primer application, you just need to develop the load with that primer is all, and make sure the firing pin is impacting with enough inertia to reliably detonate them due to thicker cups.

OAL - The oal of a factory round really means little. As reloaders we have the ability to tailor our OAL's and other aspects of the load to feed, fit, and function in our firearms, not every firearm like factory ammo specifications are. Generally, I like to find an OAL that will fit the magazine, feed reliably from the magazine, and pass the plunk test, which is how we check to ensure the bullet isn't contacting the lands when dropped in the barrel.

I honestly don't even look at published OAL, I use the barrel/chamber as my gauge. I prefer to use the longest OAL that I can, provided neck tension is acceptable and of course fit, feed, and function are all 100%. If this coincidentally happens to be the same or similar to the published OAL, so be it, but I'd probably never notice anyway.
