dumb ? I just have to ask

[DM1906]

Federal primers are an animal all to their own (or used to be, anyway).  They're really great for light-strike race guns, but not so good for service-grade guns (heavy pins/strikers), in my experience.  I don't use them, unless I have to, and haven't in over 10 years.  I've ruptured plenty of them to know better.  The small rifle primers do well for use in small pistol magnum loads, as long as the pin/striker/hammer hasn't been lightened.  I don't know that the "softness" is the reason for Lee and others not recommending them for "auto" cappers.  The problems I've had with them is flipping in the slider type cappers from time to time on 4 of 5 progressive presses I've used, although never a problem with rotors.  I don't have any with APS, so that may not be a problem at all.  The Federal match-magnum primers (I don't remember the number, or if they're still available) on the other hand, do very well, but cost 3X last I looked.  I've never had one detonate while capping, even when stuffed in sideways or inverted.

DM right now I am stuck using federal primers as I got them on the last shortage and havent seen a win lp primer in a good bit.   But when I do I will get a bunch of their lp and small pistol primers.   

Now just where to find them
