Why are these the only primers available for large magnum rifles? Do they suck or something? Looking for primers to reload .300 win mag with H1000 and having trouble finding the Federal 215's?

Can you find CCI 250s?
They are a good primer, they work good with really slow powders or ball powders

They work fine in my 7mag, I think they were just the first ones to ship their primers. At my local outfitting store, Winchester pops up more often then CCI or Rem, folk just snatch them up and Mags and shotgun are always the ones left.
The normal Win LRP's suck and have pin hole blow outs a lot. I dont know if the LRM's have the same issue. Something with them removing the coating a few years ago, but not increasing the size of the cup to account for the lack of coating, thus making them ever so slightly undersized.
Have been handloading far longer than I want to admit! With that being said, I've always had great results with Win LRP & LRP Magnum primers! Never a failure. Can't say that for any others but CCI! If pin hole blowouts are occurring, it most likely is due to other issues, either mechanical or load being too hot, or maybe even a headspace issue.
I've used Winchester blue box primers almost exclusively for the last 10 years. I've never had a problem.
Newbie. They used to come in white boxes.
I just meant EXCLUSIVELY. CCI used to come in green and red also.
Because they suck? they are all mil spec
