My buddy gave me 4K worth of Remington 6 1/2 primers. I want to load them for my .223/5.56 16" AR but I have found no loading data for them.

What's the deal?

Are they safe to load then fire through the AR?

Looking at a few primer cross reference charts it's showing that 6-1/2's are equivalent to WSRs, CCI400s, and 205s.

NO, they are not safe in .223. They are meant for .22 Hornet level cartridges. i've been through this already. DON'T do it.

I can personally verify this, I have a ruined bolt because of my own ignorance. 6.5's are for Hornet class loads, 7.5's for .223/5.56 class loads.

I loaded 1k of those for plinking ammo. Primers pierce too easily even with light loads. They put an annoying dimple on the tip of the firing pin. Won't buy them again.

Quick question while we're on the subject..I have a couple thousand Rem. 7 1/2 "benchrest" primers..what's the difference between these and regular 7 1/2's? Safe to use in .223/5.56 loads?

PLEASE VERIFY THIS ON YOUR OWN, but I saw on a different forum where some folks use these for loading up .38 Special cartridges.

I bought a couple hundred when the last shortage was going on and did not read the (very) fine print til later. Then, I had 200 primers I could not do anything with.

Rem 7 1/2's are good to go. As for the difference if I'm not mistaken is a little harder cup and consistency of ignition properties.

I couldn't really find much on the difference. If I had to guess....better QC. Yes, they are good for .223/5.56.

The only time I've seen guys using rifle primers for pistol cartridges is for things like 9mm major loads for IPSC open guns where the pressures are way beyond SAAMI standards. Some fellows just like to fool around with stuff, I suppose like using Rem 6.5's in a low pressure 38sp.

I would have no problem using them as small pistol primers, especially in something with a larger case capacity like 38/357. Just back off on your load a little bit and see how it works.

I really hate that they sell the ****ing things - there is no reason to have a small rifle primer that is unsafe in the most common cartridges that use small rifle primers. Who the **** shoots .22 Hornet in quantity anyway?

Missed this the first time around... around here we call that a Blue Falcon :D

I googled'em after I posted, and pretty much came up with the same thing, supposed to have a little thicker cup, several places rate it the same as a magnum primer..
