    So for all my small frame ARs I've been using CCI #41. I've been shooting a ton lately, and they have treated me very well. Problem is like most, I can't find any in stock. Came across Winchester #41 primers I'm stock.

    Anyone ever compare the two? How were the SD/MV compared to the CCI? Just don't want to buy them and have them be garbage. I know they are different components, but I've had nothing but issues with win brass, and no longer use it. so Im just checking

    Thanks fellas

    No experience but I did see a couple of bad reviews on one of the major reloading dealers. Two or three claimed they had failures to fire.

    I hope they work because I bought a shitload of 'em lol.

    I don't believe/buy much of the "theories" out there concerning primers and/or priming seating depth wreaking havoc on loads... I do believe in weakened firing pin springs.

    Do CCI450's/magnum SRP's seem to be more consistent (possibly lower SD)..? Yep, they do, so I generally use them. But CCI#41's work great too, the same really as far as I can tell.

    Somehow, magically, my guns that fire lowly CCI200's and/or Fed210's shoot just as good and get low SD's as well.

    I think it's a good bet that the Win#41's will go bang too.

    my bad, but no. If you look close, you will see the 5 with holes blown in them.

    Ok I get it lol.

    I just played captcha and saw the 5 with holes...

    I don't have any experience with that, what's that a sign of? That's never happened to me, I've never seen primers do that and I've shot a lot of fucking guns over the years hahaha.

    I'm guessing pressure?

    #41 primers tend to have harder cups than standard primers. I would speculate that the failures mentioned are due to failure to seat the primer to the bottom of the pocket and set the anvil or a weak firing pin spring.

    The anvil is positioned further away in order to be less likely to experience slam fire, its not that they are harder/thicker materials

    CCI used to have this published on their website but it appears to have gone poof.....

    Take any AR and drop the bolt on a loaded mag and send a round into battery

    Then remove the round and inspect the primer.....you WILL see an indentation on the primer cup from the momentum of the firing pin being driven forward when the bolt goes into battery.

    Well, guess I'll find out lol.

    I never push pressure in any of my rigs, so maybe I'll have better luck (maybe not). I'm also looking at these for bolt-gun stuff which might yield better results (I honestly don't really know dick about loading for an AR because I've never done it).

    That said, looks like that 23.6gn XBR load is still just below Hodgdon's max (23.8gn)... in a 24", 1 in 12, which nobody shoots of course haha.

    Thats a 223 load based on listed pressure.....you have a ways to go before you see pressure issues......assuming you're using 556 brass not 223 in a 556/wylde chamber ar

    your COAL can go out a ways too and still fit in a magazine......I load right to the max 2.260 and they fit in usgi mags and run without issue

    I did a little more digging and seems these Winchester #41’s are a result of them getting a big contract to take over the Lake City ammo plant:

    I find it hard to believe they wouldn’t be able to get their shit together as far as primers go with them making billions of rounds and with millions of dollars on the line.

    I probably won’t get into mine for another year or so to see for myself (unless I just decide to in the name of curiosity), but hopefully a small sliver of that reported 28 million went/goes to not putting out shit.

    Good shit, and research! Thank you for this. I'm really starting to not like Winchester though. I bought 7 bags of winchester 223 rem brass over a 4 month span. Different lots too. I got 90 pieces out of 700 that had uniformed flash holes, and that was being generous. 95 percent of the flash holes were oblong or looked like they were double punched or extremely off center. Massive differences in OAL etc. Now, the issues that are being reported with the primers. They just seem to make sub par shit, so it makes sense they'd get a huge contract. Haha

    Do they make Primers and Compound at Lake City? If they do, then the Win #41 will be the same as the CCI #41 since Winchester now runs the Lake City ammo plant. They are not allowed to deviate from the established formulas from what I've read and I would imagine primer composition can't change without another testing campaign. I'm not sure since I don't know the specifics but that is my assumption.

    Curious if anyone has had more and more recent experiences with the Win 41's, they seem to be more available and substantially less than the CCI 41's!

    I’ve burned through about 200 of them in the last 3 months and haven’t had a single issue, but that was in a bolt gun. YMMV

    The dreaded pin hole primer failure. This was a problem with certain lots of WLR primers starting late 2000s. There is a recall on problem lots. I emailed Winchester my lot numbers, photos of damaged bolt faces, and they sent me 5000 new 2023 production WLR primers and $300 to replace two ARC Nucleus bolt faces.

    I was just researching these #41 Win primers and saw this photo of yours. Damnit!
