Primers 223

[MarinePMI]

You'll notice on post #2 or #3, the thickness of CCI SRP, are the same as the rem 6 1/2, and CCI specifically calls out, not 223, but AR rifles.

A PRIMER ON PRIMERS

So apparently cup thickness isn't the issue with .223, per se it's dangerously too thin. Rather, you can't run it as high a pressure or in an AR. As per usual reloading best practice, start low and work your way up, and you'll be fine.

Or just go magnum from the start, it's reported elsewhere that magnum SR primers don't have any difference in the compound, just thicker cups.

There is a synergy between some primers and powders , for example CCI 450 and N133 seem to work extremely well in the .223 for me . Changing primer for my 243 saw the group size half when using R19 behind a 105 Amax .

Or just use #41 SRP's. Again, thickness isn't the only variable, hardness is as well (as is distance between the primer anvil and cup itself, which is what the #41 does to ensure less chance of a slam fire).

Some magnum primers are no different in brissance than a standard SRP, but some are much different. Lots of variables change between manufacturers of primers. Hence the recommendation to always re-work up a load if changing the primer from one type/brand to another.

And of course, all new components need a work up, hence my suggestion to go with a SRM to start.

Any small primer you can get will work just fine.

Nope, you need one designed for .222/.223 pressures not ones designed for hornet pressures such as the Remington 6.5.

It appears stocks of Magtech SRP are available UK wide. Saw some last week at £7x100.
There is a good on line review of them and Laurie spoke highly of them in one of his articles suggest you get 1000 if at all possible.

Arron Wheeler has the Magtec SRP in stock, I use then with good accuracy in my Tikka CTR 223

Haven’t found a problem with the first 150 rounds I have tried

No they are not “crap’.

 

[trickie]

Like the first 2 replies, I’ve had no issues with about 130 rounds so far

Hopefully, Putin will be dead by the time I run out of primers.
