Winchester does not differentiate between standard and magnum LP primers?

[Patrick L]

Hi guys, wasn't sure where to put this, we have a "powder" room (ha ha) but I don't see one for primers.

All my reloading career, I've been sort of a CCI guy. No real reason, it just worked out that way. Then, when I got into DA revolvers with lightened actions, I preferred Federal for handgun ammo due to their sensitivity. Still CCI for rifle. But again, those were the only reasons. I don't think any primer is bad

Well, with all the current foolishness, I think I'm going to start a bigger stockpile. I was in a store today that stocked Winchester, and the large pistol primers said "For standard or magnum loads." I never heard of this, but again I've never really paid attention to Winchester.

So are they more of a magnum primer? I've never used magnums, even in my .357 and .44 mag loads. since I use 2400.

Anyone know?

I think that you will find that answer in the following thread that I did a site search to locate. Rather than try to re-invent the wheel, just click on the link. Outpost does a much better job explaining than I could.

Hi,
I use both CCI and Winchester. I've used the Winchester LPP for both standard and magnum loads, and haven't had issues in either. I'm not sure if the brisance is the same as that of a CCI #350 Magnum Pistol Primers, but if you're stocking up, it certainly won't hurt to have them.

It would seem that the WLP primers are "hotter" than a standard CCI or Federal, based on the thread that this was linked to.

I guess since I load primarily light target loads, I don't think I'd get into any trouble.

it doesn't make a difference. if your trying to squeeze the accuracy out of it, you will try different primers after powder, case size/weight, trim the inside/outside case neck, bullet weight will be the same, before the primer....ehhhhhhh, i used to do it on my 20 vartarg, trying to squeeze out a .00001" , ehh it makes my head hurt.

nowadays, i use whatever, winchester, federal, cci ...to name a few. a winchester large pistol primer is in my 44 mag and 44 special, but i use unique. back in the day, i used a ruger srh in 44 mag in 240gr xtp with a hot load of win296 and a win lpp.

[fredj338]

mag or std is about the brisance or amount of flash. The mag primers are hotter. Win primers are sort of tweeners, not quite magnum, but not quite std.

[NSB]

Note: Win LPP say for both magnum and standard loads. The Win SPP DO NOT SAY THAT. For something like the .357mag and WW296 or H110 you'd still be using the Small Pistol Magnum if you're following "book loads". I'm not trying to correct the OP, just trying to have anyone avoid confusion on the other primers.

[44Blam]

I use Winchester primers almost exclusively. But it isn't because I believe that they're better, but because that's what I started with and I just tend to look for them first.

There are guys who try to get powder charges pinned down to the 0.1 grain. I have yet to see 1/2 a grain make any meaningful difference. Provided you already use sound reloading practices, primers make a rather large difference in results, at least as big of a difference as what type of powder you are using. I can usually cut my groups by 1/4, if not cut them in half. In a recent test I changed from one primer shooting around 5 1/2" at 50 yards down to 3" at 50 yards, that was a revolver off a bench. All I changed was the primer.

in my case, its not the primers. the primer should be the last thing i change. my groups did not considerably change when i changed the primer, rifle or revolver.

the change in primers is considerably smaller, .0001 - .250". the change in powder weights and different powder is larger. thats why i don't care about what primer it is, be it winchester or cci or federal.......

in hunting situations, the primer is the last thing you would think about. in benchrest, you change the primer brand and the .1gr of powder to get a leg up on the competition.

[Rich/WIS]

Winchester primers are formulated to ignite their ball powders which requires more heat to light off then say IMR powders. When using ball powders I use mag primers, started this after getting a set of electronic muffs and there was an occasional but definite click of the firing pin falling before the boom. This stopped with the magnum primers when using Win 748 or Hogdon BLC2.

To further add to the confusion, Winchester makes(made) large rifle primers that are designated WLR, yet the white boxes state for standard or magnum loads, while the blue boxes state for standard rifle loads! Both colors of boxes are labeled WLR!

[DAVIDMAGNUM]

Well here is my two cents. In the 44WCF (44-40) , in two rifles, three different powders and four different loads, CCI beat WLP. With Trailboss and WLP at 100 meters the vertical stringing was taller then the rams (lever action silhouette). A center hold on the animal could result in miss going under or over the animal. Changing that load to using CCI#300 with all else being equal brought the 100 meter group size down to a round 1.5" group in my 1892 . With a trickled case capacity load of Reloader 7 WLP left a lot of mouse terds in the barrel and vertical stringing at 200 meters measured in feet, not inches. Switching the primers to CCI#350 with all else being equal created 4" to 5" 200 meter groups and very few mouse terds in the barrel. With a full and reduced with a wad load of Swiss 2f WLP created hard dry fouling just ahead of the chamber. Again everything else being equal witching to CCI#300 cured the hard fouling problem and increased accuracy in my Uberti 1873 Winchester.
For me at least WLP is too hot to be a standard primer and too weak to be a magnum primer. I know that there are folks using them and love them. I am not trashing them. But for me using Trailboss, Swiss Black Powder and Reloader 7 stick powder WLP don't work.

[BigAlofPa.]

Here is my experience with them. I was having issues with blue dot not burning completely in 10mm. Using the Winchester LP. I tried CCI LP Magnum. And it cleared up my issue.

[robg]

i found win pistol primers shot higher than the cci primers with the same load .had the same difference between hornaday checks and gator checks.maybe higher initial pressure peak.

What 44Blam said.

[Norske]

Why not use the primer that the reloading manual used?

[greenjoytj]

When ever I look to buy the recipe listed primer it always out of stock.
Same for all the other components use in the recipe.
Where does the pressure testing labs get their cartridges cases at the length specified in recipe?
I’ve found the cases new in the bag or box not to measure to the trim to length.

I try to buy only CCI mag primer when I can find them to reduce inventory load.
A ctg that doesn’t require a mag primer gets a slightly reduced powder charge to compensate.
Federal is the only primer I try to avoid due to the LEE tool instructions cautioning against loading a whole package of Federal primers into a primer tray. I have been forced to use what’s available many times.
Will buy Federal GM215M if I find them.

Because the white WLR boxes were used when Winchester only made one large rifle primer, the WLR. Now, with the blue boxes Winchester makes the WLR and a WLRM [Large Rifle Magnum].

Interesting, I did not know that Winchester now has the WLRM in blue boxes as the store I frequent doesn't seem to stock them.
Larry, have you done any testing on WLR vs WLRM?
