I am having a problem with my 500 S&W Mag handloads they aren't igniting exactly when the hammer hits the primer there is up to a second or 2 delay & i am stumped here is the emtire load Cal. 500 S&W Mag- Case Starline- Primer- Wolf Large Rifle Standard - Ramshot Enforcer 42.0 grains- Rainer LS 335 grn TCPHP bullet . The loads haven't been exsposed to any dampness or moisture matter a fact 2 of the loads didn't even fire the primer pushed the bullet into the bore just a bit had to use cleaning rod to get bullet out I have over 350 of these loaded i did contact Ramshot & they said i should pull the all & use Winchester or Federal Primers , What are you guys thoughts let me know :banghead:

My guess is that the primers are not quite seated well enough and not firing off quite like they should (But how if they do go off? I would think if they fire at all, it would be full force. hmmfh), or they are not powerful enough to set the large charge off well. (More likely.)

I have heard of hang fires, but never had one or saw one first hand.

Have you had success with this load with other primers? Does the powder fill the case. Is the powder against the primer when you fire?

Wolf Large Rifle Standard

I don't reload for this caliber or ever expect to get one. But I would be expecting a Mag Pistol Primer. My load books are not handy to check to see if this is the right primer. Rifle primers have a harder cap than pistol primers do. Using this primer should get you enough energy to ignite the powder. If not fully seated you will get FTFire's.

If you had some primers only go off, and drive the bullet into the barrel, was there any powder?

Never have experienced hang fires.

Sounds like a primer problem. Make up a few rounds with Win., Rem., CCI, or Fed. primers and see what happens. And as Walkalong said, check to make sure the primers are seated correctly, i.e., seated slightly below flush.

There's another issue involving primers having to do with the older vs. newer cases. See here and check. This could be your problem:

When they fire after the delay, do they feel like full power? I have Zero exp w/ this cartridge; I would try some mag primers and a very heavy roll crimp.

Edit: It sounds like the primer is having a very tough time igniting the powder. On the rds that didn't fire, I think that was just because the crimp didn't hold the bullet long enough for the powder to ignite. I think you need more primer.

I made sure that all of the primers were a little below flush during the priming step & the ones that didn't fire at all did have the powder charge in them I am leaning toward the primer is the culprit oh this round was loaded for my 500 S&W Mag Handi Rifle i don't have the handgun

I had a similiar problem with my .45 Colt and fixed by going to a magnum primer. At that time it was more of a click - boom and yes once they fired they felt like a full power load. You standard primers may not be hot enough to ignite the powder as quickly as it should.

Some powders,if the primer goes off and doesn't ignite the powder good,the pressure from the primer will push the bullet out and never allow enough internal pressure for the powder to actually burn.It will act like you never had powder in the case.A good crimp that the primer can't budge will help,but if the powder doesn't ingnite good with those primers,it may not matter.

Yeah 500mag takes rifle primers.

Then why did you answer his question?

The 500 S&W has been using large RIFLE primers for a long time. The first few cases took large pistol primers, but they couldn't stand the pressures generated by the big 500, which operates at rifle pressures. The way to tell is a "R" somewhere on the case head, designates the brass is cut deeper in the pocket for large rifle primers.

Trapper, I have not used enforcer for my 500 handloads. Only use W-296 and H-lil-gun. One load for 440 cast loads I use longshot. Never had a hangfire while using standard win. large rifle.

I did check each case for the 'R' & if a case doesn't have it its ment for a large magnum pistol primer I was told i could just ream out the primer 002" & the cases will be good for the rifle primers

Amen. I was wondering when someone would speak up about the LR primers.

I've probably got 1000 rds through my 500 S&W and I've never had a problem with any of the powders I've used (H11-0, AA9, LilGun, H-4227) with standard rifle primers. Mag primers are not necessary. Did all of the primers come out of the same tray? If so, throw those SOB's in the trash. They're $5.00 /100. Get a fresh tray from a different lot or different mfg. and go to town.

2 of the loads didn't even fire, the primer pushed the bullet into the bore just a bit Rainer LS 335 grn TCPHP bullet - Plated bullet? =no neck tension=bullet jumping crimp when primer fires. I dont own one, never will. But you get my 2 cents anyway. :D
