Are you shooting an AR-15 with a lighter trigger and spring?? I had the same problem. You have to make sure it is clean and lubed. I thought about putting the heavier spring back in!!

No this is an H&r single shot in 223 I purchased for a backup gun for prairie dog hunt, the trigger pull has been lightened but the hammer spring is unaltered.

Did you remove the primer pocket crimp from the brass before you loaded it?

I did have some trouble seating some primers

That's the problem.  They're not seated fully, so the impact from the firing pin is pushing them forward (seating them further/fully), but the anvil in the cup has no support under its legs, so even though there's a good dent it's not compressing the priming mix and igniting it.  Get a primer pocket swager (or a cutter tool to do the same thing) to remove the military crimp, seat the primers completely, and you'll be in business.

Likely ain't the primers, those Handi rifle triggers have to be pulled their full travel. If not, the transfer bar doesn't drop all the way and you don't get a good strike,
Had the same happen to me,,Did they go off the second time?
 I'm used too double pull set triggers on the ml's, I have the "set" adjusted to a feather touch,,The Handi's don't work like that,,ya gotta pull that trigger all the way back,,

I have not any trouble with my Handi rifles, but I have not tried the mil spec primers. There are some that have had to switch to a primer with a softer cup. Winchester primers have softer cups and usually solved their problems. I use Remington 7 1/2 and do not have any issues, they have a fairly thick cup, but not as tough as the mil spec primers. BTW if you lighten the trigger pull too much you may get light strikes on your primers as well. I did that once on one of my rifles and had to replace the trigger and hammer and start over. This only applies if you lightened it to the point of being under 16 -20 oz pull. I advise to not lighten it to less than 2 pounds. Also, some times the hammer spring will go weak for no apparent reason and not make good primer dents. You will need to replace the spring if this is the case. Good Shooting and Good Luck

This is the first thing I thought of as well....  WELL did you swage the primer pockets?

Mil brass usually crimps and seals in the primers. They will pop out with reg resizing/depriming dies. (Have you broken many decapping pins?) The brass needs to be corrected before re-seating a new primer. The best method is to use a Dillon or RCBS pocket swager. If you careful, the LYMAN "space ship" deburring tool can also be utilized to remove the crimp. (Maybe try this first tosee if its actually the problem.) BUT BE CAREFUL as you can easily remove too much material. The best choice is the swagger.

The result in NOT doing this is exactly what MZ5 has explained to you.

CCI 450's are not Mil.Spec. That would be the CCI primer #41.
I've seen several comparison charts, and the .223 almost always recomends a mag primer
The Rem 7 1/2 as listed by Rem is the Bench Rest version of the small rifle 6 1/2, but several/many sources consider it a Mag primer.
I really hope most know a mag primer ain't about being "hotter"..
 I guess for me I wouldn't/won't use mil brass unless it's the only thing i could get, every thing I've read says the heavier case = higher pressures, plus the extra work to get the primer pocket right. Again if it's the only thing I could get,,I'd use it,,better than not loading

If the little anvil legs are not on the bottom of the primer cup they will not fire no matter how big a dent you put in them.  It just pushes the anvil out the back of the primer cup.  Larry
