Some powders are harder to ignite.I was doing some fire lapping with a starting load of Reloader22 in my 300 Win Mag with standard CCI primers once.I had several hang fires,click,delay,then bang and a couple click,no bang,wait,wait,wait,is it going to go off wait,wait,I don't think it's going to go off.That will give you a scary feeling inside when that happens.I pulled the bullet and dumped the powder when I got home.The powder was sooty black but none of it had ignited.If you get any signs of delayed ignition,don't use standard primers in a magnum.
Your Fed 210 primers are the hottest of Large Rifle Primers. So on a good start there. Most of my case only hold about 75grs., and I use the Fed 210 primers. I also use H4350 powders or on that line. Most of my barrels are 26" long too, with the H4350 being a little faster too it must be getting the job done for me.
HOLY MOLY! I probably would have had to change my shorts once I got home too.

Had a bad batch of CCI Large magnum Pistol primers about 25 years ago doing the same. Shooing out of a revolver. Yeh, its uncomfortable.

Here is my experience I had two weeks ago working on a load for the 6.5 PRC, using Alliant RL26 powder, first chart are magnum primers and second are match primers, both are Federal brand. You can see that charts are repeating each other, SD and ES are similar for the same amount of powder but the speed is consistently lower where non-magnum primers were used.

I compared the velocity in my 300 WSM between a WLR and WLRM primer.I was getting about a 15fps lower velocity ave. with the WLR primer.WLR is supposed to be one of the hottest non-magnum primer.Now I just use WLRM primers in my non-magnum rifles.
I head that way for work occasionally, I will definitely let you know if I am in the area.
I can't shoot this weekend, but next weekend I will let you guys know how it goes. Hopefully it works out or I got a real expensive stick in the safe for the time being. I refuse to pay something rediculous for primers or powder.

My experience with non-magnum primers used in 7rm is a perceived slight delay. Switched back to mag primers and no issue. ???

This is somewhat related, but in regards to pistols... I'm working up my first hand loads for my Marlin 1894, and was wondering if I could use normal large pistol primers for some plinking loads in .44 Magnum?
I don't have any large pistol magnum primers... but have a few hundred standards.

About the hangfires...
Yeah, watched a scary video regarding this.... older guy bench shooting. Click, no bang. He looks at the gun, then re-cocks it and fires again. Click, no bang. He looks at the gun puzzled for a while, then lays it on the table. He decides to get up. He's half way stood up when the gun lying on the table goes off!! Scared him so bad he fell down! Scary stuff!
Had a squib load in my pistol the other day. (Very old ammo.) Bullet half way down the barrel. I stopped. Wondered with how many of these new gun owners, they'd have shot again and blown the barrel...

I have always used magnum primers for all of my rifle loads. It is probably because when I first started reloading about 45 years ago, I read the current Speer reloading manual to learn. It called for magnum primers for all of the rifle loads.
I missed a loading on one shell when I first started loading about 30!yrs ago. The primer was enough to push the round into the barrel. I had a flat brass attachment that I used on the end of my cleaning rod. And with small taps got it loose. I thought I was going to replace the barrel. Took it to a smith and had the bore checked all good. That's why I stand up and shine a light into each case to check that they are all have powder
