I have seen it said that the CCI milspec primers are in fact magnum primers, but that they do have harder cups.
cci primers
quite a while ago i read a article in the shotgun news about different primers and there was a section on cci no 34 primers i read it carefully because i was using them and there are 2 cci no 34 primers one is a regular mil spec and the other is a magnum the only difference between the two is the last product number mine are 0002 and the magnum is 0003

You are saying I can't, when I have actually already done it. It IS possible and I HAVE Done it. I can post some pics of rounds I reloaded and fired if the proof is required. Please talk from experience, not hearsay. I'm going to be doing some 7.62x54r with some steel cases I found a while back today as well. In the second pic you can see the base of the case, where a CCI #200 has replaced the berdan primer, and been fired. Please note the nail polish around the edge of the primer. I did not modify the steel case in any way, and I popped out the old berdan primer with the water method.
This reminds of the story where a man jumps off the top of the Empire State building and as he was passing by every floor he was heard to remark "so far so good"!!! I think the comment about your reloading technique is not that it can't be done but that "it shouldnt' be done". You are asking for an eventual catastrophic case failure in your gun because:
1. the primer is incorrect size and application
2. your using steel casings that are much more brittle than brass and were not intended for reloading.
The steel case will not expand the same as brass and will crack often on the first shot. Please for your safety and others around you do not continue this unsafe practice inspite of the fact that it worked (the powder ignited and the bullet went out the barrel) in the past. Phil.
A guy down in the states, who has been reloading for a great many more years than me, reloads steel cases. If a steel case will not expand like brass, why does all my mil-spec czech ammo work so beautifully? I'm not talking about my reloads, but the original ammo that everyone buys. You don't hear of people having gas leaking back into their chambers when firing the regular stuff, or does when you reload it, it makes the case unstretchable? Brass hardens when stretched and compressed much quicker than steel does. As well, the primers aren't *that* loose, I've had brass cases that have had hot loads in them about the same after a couple of loads.
Some time ago I did a fairly un-scientific test of CCI 34 & 41 primers compared to the typical lot of the most common other brands (federal, winchester, CCI reg., Remington)
In both instances I loaded sized & primed, cases into the chambers of one of my ARs and let fly the bolt home, and checked the primer dent.
In all instances, I noticed no variance in the dimple created from one to the next.
My understanding is the cup itself are near on the same from primer to primer, and it is the anvil that is the difference.
While I have used Federal 210Ms in my M14, I try to stick to using Winchesters. It certainly can't hurt to be on the cautious side when hand loading.
