Primers for 45 ACP
FWIW I have found that CCI primers are very slightly larger in dia. than Win. and a bit more difficult to seat. I have a Lee Prog. 1000, not the beefiest press around, have to be gentle with it and I've had some problems with them. For me, the Win. are ideal, Fed. ok too. Bill in Pa....

I had a gun that shoots them fine, there's nothing wrong with
them at all. These are one of the primers recommended by Lee
for use with their priming system, they are safer than some
others notably Federal. Although either primer can detonate
in the loading press if they get crooked and are crushed,
the Federal might set off the whole tray but CCI won't.
However I had the gun worked on by a pistol smith, mostly I
wanted the single-action lighter and the double-action smoother.
When I got it back, the single-action was largely unchanged and
the double-action was a lot lighter instead of smoother.
Apparently he accomplished this by lightening the hammer spring,
and it no longer shoots CCI reliably, just doesn't hit them
hard enough to detonate every time. I haven't had time yet to
get a new spring and put it back like it was. But Federal
primers still work fine.
So CCI primers are the safest for reloading because they are
harder to detonate, but this can cause a problem if your gun
doesn't hit them hard enough.

Joe, the Star machine seats the primers on the down stroke and seats every
one to the same depth. If the shell plate is adjusted right each primer
will be slightly beyond flush. You do not have to clean primer pockets but
old military crimped primer pockets will occasionally hang the machine up.

I think you will find CCI and Winchester primers have a thicker shell
making them require a little more force to seat in single stage presses and
Dillon's. My favorite for more than one reason is Federal.

Members,
To see how uneven the CCI primers are, just pick up 100 in
your plastic pick up tube. Now look at it from the side. You will see
some of the anvil is sticking out of the cup. Where you can pick up 100 easily on the
REM, WIN OR FED, you will notice CCI is either full or not able to pick up
all.
Since Winchester came out with the brass colored primer I found some to be on
the thick side where I did not have that before. Now I stick to Fed for
50yds for it consistentcy.
Try it out.
