ooopppppsssss wrong primer

[HunterGreen]

Hello, hope all is going great with everyone.

I enjoy competitive shoots. Today as I was cleaning and preparing my cases, I accidentally put in my 243 win lapua case with federal large rifle magnum match primers instead of federal large match rifle primers...

Can I still shoot these ??
Has anyone seriously screwed up like me ??

If you're shooting anywhere near a warm load with a regular 210 LR primers....I sure wouldn't even attempt to try it with 215 LRM primers.

Fed 215 LRM's are the hottest primers on the market, if I remember correctly. That could be bad.

I guess am screwed, I shoot flies butt hole with RL19 44gr of powder seated 2.254 ogive 105gr amax fps 3355 +- 13fps 30inch tube useful rifle 27.65 inches. ..

So I will knock it down to 42gr just to be safe

I don't know if 2gr of powder is enough...

I'd wait for some other to chime in.

Personally, I'd dump them and pop the primers out and start over with the right primers.

Hey guys, not to hijack this thread but I am new to reloading and was wondering how you get the hot primer out of the case. Can you just put the case in the press and remove it ? will the primer set off ?

Yes you can, I've done it and would guess many here have also done it. Just to be safe, wear eye and hearing protection

ditto... did a few hundred when I sold my 7rem and moved some of the brass.... pulled the bullets, saved the powder, and kicked the primers out to use elsewhere. Be careful here as if you are rough it could be a problem. It's best not to get in this situation to start with or fire the primers in empty brass in a properly chambered rifle though.

When I developed a 30/06 180gr load w/ 4350 I reached 57gr as max with a #210. For hunting I went down one grain to 56gr and used a #215. @ 35°F the velocities were the same. You're two grain reduction should be fine.

Its so hard to get good primers. I will pop them out, I just hope I dont damage my precious primers

I run fed mag primers in my 06, I wouldn't punch those primers out I would just work up checking the usual pressure signs

I agree. Removing the primers could damage or change the detonation of the primer compound since the depriming pin will contact the anvils, which will be impinging directly onto the primer compound.

It's a magnum primer, not too much different than 210M primer. Reduce the powder charge two grains from what you were using with the GM210Ms and work up your load, as desired.

^^^^^This with enough rounds for an indicator to see if muzzle velocity variation is similar, improving, or worse along with precision. You never know. Why not try as long as you are there part way. You can always punch the remaining primers if results are not where you want them.
