AMMO Problem??

[Qaib Thai]

so i went to the range today using remington core lokts and hornady superformance. started off with core lokts to sight in my gun since i just got a new scope and the ammo was cheaper. once it was sighted in i switched over to some hornady superformance and shot a couple rounds then all of a sudden after one of the shots the bullet didnt come out. i took my key and got it out. shot like 3 more hornady rounds and they all were getting stuck switched over to core lokts again and no problem. also when i took out the hornady bullets i saw that at the edge of the bullet it was bent and even on one of them was broken off. i looked at the remington rounds and they seem to be angled a little bit to but not getting stuck. so i was thinking that it was either the bullets or the gun but leaning towards the trigger hammer of the gun or something thats in the gun. could possibly be the thing that pulls the ammo back out since my 30-06 is semi-automatic. any ideas posted some pics so you guys see what im talking about.

dunno how to make pics smaller size to big enough for 1 pic..

Dude those are bullets those are the cases. And it sounds like thos superperformance rounds are too hot for your semi auto. Thats why the remingtons work better in your gun.

way to hot for your rifle and now you probablly have a messed up extractor

Are the remington's that you shot before the hornady's damaged also, or just the remingtons you shot after the hornady's.  If the first ones you shot were damaged, you already had the problem before the hornady's ever made it into your rifle.  They may have magnified the issue but didn't cause it.  On the other hand, if the first remington's fired had no damage, then yes it was probably too much pressure on the hornady's and when the semi-auto extracter tried to pull them it couldn't because they were jammed in there.

Quaib is that my imagination or is the primer pushing out on the case on the far right in that first pic? It looks like the cases are sticking in the chamber of your rifle and the extractor is ripping a chunk out.

I would contact Hornady about this and see if you can't get a refund or replacement for that ammo, looks like a good idea to stay with the Remington and make sure the chamber in your rifle is clean.

Definitely looks like too much pressure shoving those primers and expanding the case tightly into the chamber.

over pressure? Does the hornady box say anything, certain firearms that should not shoot this ammo???

[madmack76]

those super performance rounds are way to hyped up to be shooting out of a auto loader

Here's a little info.

heres how a gas operated semi auto works.  theres a port in your barrel that allows gasses to travel back to the bolt and push it to the rear.  there is then a spring that pushes the bolt forward stripping the next round and seating it in the chamber.  when the round goes off the case in turn swells up.  if the bolt is forced to the rear before the case has a chance to shrink back down it will rip the side of the case exactly as your pictures show.  this is common with people who shoot carbine length ar15s and steel cases.  I would doubt your extracter is damaged.  keep to the lower pressure rounds and you should be just fine.  im not sure how your buffer system works but i know a lot of guys will run a heavier buffer in their ar's to help slow the system just enough to keep this from happening.

Way to hot for that gun...

Is that a 7400?  Bad juju shooting hyper performance rounds through them...

Browning BAR is another animal all together, and would probably be safe...

Dannysdaddy sounds like your probably right. if the extractor was damaged it wouldnt be extracting the corelokts. i wont be using hornady rounds anymore and i get better groupings with the corelokts anyways. dont know if it makes a difference but my 30-06 is an old woodsmaster model 742. could possibly be since its an old gun but its in good condition and everything is lubed up.

You are way over pressure in that old gun..... wonder it did not come apart on you....

been doing some research on my gun and seems like its a common problem in the remington woodsmaster model 742. sounds like cleaning the gun after 6-7 rounds due to burnt and unburnt gun powder left in the chamber causes the case to get stuck and the extractor ripping a piece of the rim apart
