.223 AR-15 Reloading/primers & Crimping Questions

[DinDinA-2]

I ran a search for primer & crimping information for the AR-15 and didn't find quite what I was looking for.

Currently, in Alaska, it is nearly impossible to find bullets, primers and powder for handloading. One has to go to Sportsmans Warehouse every day to "get lucky' and take what you can get. Forget shipping, except for bullets.

So, here I am... with an assortment of primers. CCI 400 Small Rifle and Federal 205M Small Rifle Match and a few Rem 7 1/2.

The gist of information I have found says that any small rifle primer should be ok for the AR-15 reloads IF seated to the proper depth. Some say only use the CCI 41. What say you??

Also, an assortment of opinions are out there regarding crimping the bullet for AR-15 reloads. I have been reloading for bolt guns for years, but this is my first for the semi-auto. I do not want to go down the wrong path on crimping. I will be using the Sierra 55Grain FMJ w/cannalure...primarily for predator hunting.

How about accuracy for the crimped vs non-crimped bullets?

I hope this isn't a duplicate request for information, but current ideas and information are always helpful.

Thanks
