Primer Difference CCI????

[Shynloco]

What's the difference between a CCI 400 Small Rifle Primer and a CCI 450 Small Rifle Primer? And please don't tell me the words printed on the outside of the boxes read differently. Thx.

Isn't the 450 a magnum? If not I believe it is a little hotter. Matt

Thx Guys. I bought 500 of the Magnum Small Rifles the other day at Turner's Sporting Goods to load for my son's AR which was all they had. I'm also loading for a Savage 223 Model 12 Varmint Rifle and just wanted to make sure those Magnum Small Rifle Primers weren't going to cause a problem and I'm seeing guys are using them successfully in the AR's. I've also got the 400's for the .223 Bolt gun to be on the safe side.

I am amazed to see that they did not include either Wolf or Tula...
