Has anybody that's using WSP primers made as of late having any problems with light strikes or trouble seating them? I'm getting ready to re stock. I am still using the older silver coated ones that were sold in the white box but am almost out.

I am using the blue box ones. I have noticed, that they are hard to seat in certain brands of cases. S&B, and Blazer in .38 Special rings a bell. Never had an issue light strikes. Bought 2 bricks at a flea market for $15 a brick. My go to is CCI. S&B are fine too. Bob

Here's one non-scientific testimonial:
New Winchester small pistol primers work really well. No problems with light strikes. *No problems seating them. I like them about equally well compared to Federal primers. I have had problems with light strikes with CCI small pistol primers in one revolver but since it's one of my favorite revolvers (very nice, light trigger) I've stopped using CCI small pistol primers.

*Using Lee Classic Turret with InLine Fabrication Ergo Roller Handle and Case Ejector System.

Yes. Had same issues with win primers. Going with cci and bench primer to make sure of seating.

I've found that non-plated primers such as the Winchesters have more resistance to seating than nickel plated primers such as CCI, Rem or Federal. But other than that, no problems with them for me.

I'm getting to really like S&B.

I use almost exclusive Winchester small pistol for suitable rounds. I have had no noticeable problems with them. I get them at a decent price (approx $125 per case of 5,000) and they work for me. I have nothing against CCI but I like the packaging better for the Winchester.) I have also used S&B with good results and they are more than a little cheaper than the Winchester or CCI.

Five years ago I was using CCI pretty much exclusivley. With intermittent supply I have branched out (Win, Rem, S&B, Fed, even Tula). I am not really noticing any difference in use. (S&B's are cheaper here and just as good so they are my current favorite.) The silvery ones just take a tad more to seat than the brass ones sometimes. Knock wood I have not had a properly seated primer fail to go off. (The ones some idiot ;-0 loaded backwards did not work to well though.)

I've had some problems with WSP's, light strikes, difficulty seating (using Dillon 550) when loading .40's. Using CCI now.

If one is hard to seat, I just try another case with the same primer. That's a little aggravating but not a serious problem, though I have lost a few primers.

I had a box of large rifle primers with several duds. That I do consider serious.

I've been using the "new" blue box Win small pistol primers and haven't had any problems with them. How ever the Win Large pistol primers have been giving me all kinds of problems.

I use Winchester and CCI SPP and have never had a problem with either.

i've been loading for 35 yrs and winchester has always been my favorite primer. I use SP,SR,LP,and LR. Years ago i tried some CCI SP primers and had misfires, about one out of five misfired in three different handguns. They were hard as a rock. The only other primer i've used were Wolf SP, i bought a box during the primer shortage and they also worked fine....Mike

I have used Winchester primers exclusively for years . I never felt they gave me any problems . I use SP , SPM , LP , LR .

No hazmat fee for 5000 at Midsouth. I couldn't pass that up. $28. Per 1000 ain't great but with no hazmat fee and Federal impossible to find I thought it's okay.

I've been using them and have not had any trouble with light strikes or hard seating.
I do seat my primers off press with a hand tool and I make sure to seat them all the way in....to the bottom of pocket and give a little extra squeeze to sensitize the priming compound.....A step a lot of reloaders don't know about or fail to do.

I just finished off a Blue Brick of the SPP and did not experience any light strikes nor FTF with any of them in either 9mm or .38 Specials. I've noticed a few brands of 38 cases were on the snug side to seat (I use a Lyman hand primer) but not that bad. I have also been using their LRP in my 30-30 rounds and they slip in nice & easy. JMHO

I find that most problems with light strikes were due to them not being properly seated. Once I went with a RCBS hand held Primer, my light strikes went away completely.

Not really a problem, however, recently one box of 100 in a 5,000 case was empty. Completely empty. First and only time this has happened with any brand.

Sent them an email with the codes information and have received no acknowledgement. Not looking for anything from them, but thought that they'd like to know.

Other then that, they are my preferred brand of primers, but I will use others when prices are advantageous. Actually, I have never found a significant difference from brand to brand.
