I was wondering if all primers are the same diameter for large rifles. Latley I have been loading Winchester large rifle primers and they seem pretty loose in the primer pockets of once fired Federal 270 brass. I know that some shotgun 209 primers are of a little different diameter. So any type of primer that might be a little tighter in the pocket. I have also had problems with a 240 Weatherby to the point of having to put glue on the primers to keep them from falling out. By the way I use model car glue for keeping them in. Would something work better. | ||

Largest diameter federal,CCI medium and WLRM the smallest... | |||

Double check your loads. They may be a tad too hot. For me, loose primers is the first sign that I'm at a max load. Geronimo | |||

Geronimo These are once fired factory loads. I have been loading 57 gr. H 4831sc with 130 gr. bullets. This not hot at all but thanks for the responce. I will try some Federal's next. | |||

I`ve found Winchesters to be tight in somes cases and CCIs loose then the next lot had them switch places. I think it just depends on the side of tolerance they were built to on the day that lot of primers was run. I`d question any cases though that required primers to be "GLUED" in the pockets. I`ve never had a case that wouldn`t retain a primer. (Knock on wood) If you can`t get the primers to stay in the pockets I`d try another brand and if the problem still existed I`d dump the cases. The fact they are once fired factory makes no difference. The primers were held properly in the original loading and the case should be capable of do it still if the pockets haven`t enlarged.

I have found winchester primers to be .002-.003 smaller than others and have had one come out of a new Remington case after a short ride to the range. I installed a Federal 210 and the case is still going after several rounds with good snug fit from everything but Winchester LR. remington, Federal and CCI work fine in the New Remington cases. I measeured all the primer pockets and found them to be the same. A few of the winchester primers were the same size as federals but about every 4 th one was a lot smaller. | |||

with America shifting to third world mentality it is a wonder anything fits or works anymore. | |||

I had a case of (new) Federal Gold Match brass having excessively large primer pockets. It is possible the problem is in the brass as opposed to the primers... - mike ********************* The rifle is a noble weapon...

Call Federal for the primer pocket measurments. They have made a few tryin gout bigger ptimers but don't think they were to be on the market | |||

Let's not get all excited here. Recent lots of WLR primers use plain brass cups that are not coated with nickel (as had been the past practice). Winchester sorta forgot that the nickel coating added a small amount of diameter to the primer cup, so that if they wanted the cup to fit the same as one with the coating, they needed to increase the diameter of the cup. Of course, since all of this is done on existing machinery that ain't gonna happen. So, they just sold them as the came off of the machine, which makes them a slightly loose fit, particularly if the primer pocket is on the large side of tolerance. I have a large lot of these "undersized" WLR primers, so I reserve them for use in new or once-fired brass. With multi-fired brass, the fit can be so loose as to be doubtful, but a nickeled primer from another manufacturer usually seats with adequate resistance. | |||

Different manufacturers have different sizes/tolerances on their primers. In my experience, CCIs run big, Win run small. If your primers fall out, however, you may have another issue and I would investigate further before I used glue.

Nothing wrong with the cases just small primers! | |||

I am experiencing the same thing with my brass primer relationship. Winchester 270 brass and their primers, some cases the primers seat real easy. In Remington brass the same primers seat just right. But none have fallen out and I use 58 grains of H4831 under a 150 grain Nosler paetion with the WLR primer. I got them at a gunshow but the next 1000 will be CCI again. Leftists are intellectually vacant, but there is no greater pleasure than tormenting the irrational. | |||

Dump the Winchester primers. I've had problems with their fit in the pocket and have had loose primers as well even falling out after having been fired. Try CCI or Federals. | |||

Thanks for all the help. Bought some Federal Primers now all is right with my reloading world. Went back and measured the primers that wouldn't stay in the cases and found them to be about a .001 smaller than other winchester primers I measured. Federals were a little larger and much more constant in diameter. | |||

If you are having primers fall out after being fired then your load is too hot. My primers all take the normal amount of force tp remove them after firing as the pressure resizes them to fit the case tightly.
