When Winchester made the bad primers a few years back did this also include he small rifle and pistol primers or just the large rifle. thanks

I don't know but recently I have encountered several bricks of Win SRPs that will not feed through the primer feed tube of my Dillon 650.
Appears that they are slightly bigger in diameter than normal.
They will go through the pickup tubes used to load the tube on the press, but once it press they get stuck.
Real pain in the arse to have to keep taking the primer feed mechanism off the press and tab out a primer stuck in the tube.

To the best of my knowledge the issue was only with the LRPs.
They gave me 5k of the new generation and they have not had the pin hole
burn thru the old ones had. They do seem to be a tad smaller and go into
the primer pockets quite easily. The old ones were the brand to go to
when the pps loosened up a bit.
Just my 2 cents.

Winchester bought back my primers, which left me short because they were hard to find back then. Both large and small. Rifle to my knowledge. It appeared to be mostly large rifle.

Not only did they buy mine back at a good price, the incident prompted me to secure a supply of good ones, which is why I’m well-fixed now.

There never was a problem with any Winchester primers except the large rifles, which for a while had cups that tended to split on the sides, which resulted in gas leaking around the edges.

The "problem" was exacerbated because for quite a while Winchester refused to acknowledge it--until it became obvious it was widespread.

I do remember there was an issue, but many years ago. I have a bit of them and in today's situation I would image they are about gold.

winchester primers just seem to fall in to a lot of pockets on my reloads really loose compared to cci and federal

Of course, Federal, CCI and Remington primers are silver.. Happy to have what I need no matter the color of the primer.

I did a BUNCH of research on primer size (and composition) not too long ago, which is a major chapter in my first BIG BOOK OF GUN GACK.

The fact is is that while primers do vary a little in dimensions, they don't vary as much as primer pockets--even though those are supposedly similar in size, according to SAAMI (and CIP European) dimensions.

I would guess the major reason some primers don't match some primer pockets is the old tradition of adding powder to handloads until the rounds show "pressure signs."

Geez John, that hurts.

Always appreciate your knowledge and ability to cut to the quick.

When I was loading for a .300 Win Mag, I was using RWS brass and Fed primers. The RWS brass had really tight pockets and I could feel the primer "snap" into place. I use a RCBS bench top primer tool.

I had two perforations with Winchester LRM (magnum) primers. Winchester did replace them with a new lot for me.

I thought I'd over cooked my 308 brass because my unplated Winchester primers were a loose fit, but the primers were undersized - CCI and Federal fit the same cases as tight as you'd expect. (Those cases continued on to live a normal life until they died of a split neck.)

A few years ago the

When I started using WLR primers they were easier to load in the primer pocket of once fired factory loads and fresh brass than CCI or Federal (not that those two were hard.) It was like they weren't even there. This didn't bother me since they all worked and never backed out or fell out. With the most recent ones they feel like the CCI and Federal primers, so I am guessing they are larger.
