I have a progressive press Lee 1000 and I use CCI primers.

Le Baron ran out of CCI so I picked up Winchester instead, but in the instructions it claims it is unsafe to use anything other than CCI or Remington.

Is there a real danger, or does it say that for liability purposes. Someone help me out if they're able to be used cause I'm in the hole $31.99 for 1000 Winchester Pistol Primers.

Please advise


Thanks
 
Don't take this as 100% fact but as far as I know Winchester primers have been used by many in the Lee 1000 (I have only used CCI in mine). Perhaps call Lee?

The ones you really want to avoid in the LP1000 are Federal.
 
Off hand I would think thats crap. All primers are made to exacting sizing specs, so that is no issue. The only difference that I know between the primers is that the Win primers are the hottest primers of the bunch so you have slightly adjust your loads as the hotter primer adds somewhere of 2000 CUP to the load. Maybe there is a side agreement to endorce the other makes of primers ?
 
Yea I bet it has something to do with advertising. I will take it into account. When I get a chance in the next couple of days I'll load a couple hundred and share my results.
 
According to some sources (Lyman reloading Manual #49, Lee Modern reloading - 2nd Edition) there are two different types of priming compound blends. One is apparently more susceptible to unintentional discharge.

After having loaded thousands of rounds through my LP 1000, using Federal, Winchester and CCI primers, the only primer related problems I've had have been feed related, and not accidental detonation (Thank goodness!!!).
Your mileage may vary....
 
I do almost all my loading with Winchester primers and a lot of that on Lee presses and priming tools including the Loadmaster. I have not heard of Winchester being a problem, but the word is usually Federal primers cups are softer and thus easier to set of in a priming tool/press, and if the primer is next to more Federal primers it can set them off easier too. This goes for slam fires in M14/Garand actions too. Take it for what it's worth, but the problems don't seem to be reported with the other brands like Rem, Tula, Win, CCI etc. That said many millions of Federal primers have been loaded and shot trouble free.

There are in fact a number of reports of accidental detonations with Federal primers in the Lee Pro 1000. Federals are also apprently more susceptable to sympathetic detonation.

Not crap at all. Federal primers are more sensitive than others. Ever notice the packaging that Federal uses compared to all other manufacturers? Federal does this for a reason, if not, why would they spend that much more for packaging?

There have been posts on CGN over the years about detonations, and I believe that almost all have been with Federal primers.


That said, I have used many CCI and Win through a LoadMaster with no problems.
 
I have used Winchester in a Pro1000 for years, as well as CCI, both without any difficulties. On the other hand, I have experienced detonation issues when using Federal as they are a softer primer and the Pro1000 is notorious for not always aligning the primer fully and then squishing the primer on the upstroke. I refuse to use Federals for that reason(in the press) and went to hand priming everything just for a better feel and assurance of proper seating.
You will not have a problem with Winchester primers.

I've had zero problems to date using any primer that I would blame on the primer itself. And I've been using them all for 20+ years.
 
I've had the misfortune to set off single WSP's a few times in a Lee Loadmaster over the years. No sympathetic chain detonation of the other WSP primers in the feeding system.

As best as I can tell all were mechanical issues that mashed the heck out of the primer that went off. (i.e. not an issue with too-sensitive primers).

Lee used to have Winchester primers on their approved list.

I continue to use WSP's when they are available, but I've switched to separately depriming/resizing cases I'm running thru the Loadmaster. The resizing stroke is co-incident with the priming stroke. There is enough force needed for the resizing (9mmx19) that it masks any primer seating mechanical issues. By using resized cases I can feel any primer seatings issues now.
