If it said .35 Remington on the case you are shooting the incorrect ammo. You should be shooting 8mm. They are not one of the same. I would think you can do some real damage to the gun or yourself.

Let's see...the 35 Rem is a .358" bullet and the 8mm is a .323" bullet...so you were just a bit over the time pressure curve. That would actually be a straight line from your toe to the moon...it looks like it would fit just right and I'll bet your case didn't lose the neck, it just straightened out. The other had a base separation, which is indicative of a headspace problem. You should take some pics of the empty cases for us... Could it hurt the action? Well, you wouldn't have to look for anything to fill your eye sockets, the receiver would be there. Yes, it's called catastrophic failure.

sorry guys i ment to tell you all the rest of the ammo cases were marked 8mm on base seams llike some one put a 35rem load into box. i went thru ret of ammo an found one other 35 rem but it was an empty. so most of the ammo i shot was correct 8mm

Maybe you should learn proper firearm safety with .22cal arms before jumping into centerfire rifles? I don't say this to insult you it's just that you committed one of the "deadly sins" of firearm handling/use.
If you blow your face off or lose half your hand that's on you but the guy on the line next to you doesn't deserve to pay for your mistakes.

Well, not really. 35 rem doesn't look anything like 8MM. Very stumpy by comparison.

Dangerous, very dangerous ... pressure must have raise near or above proof test, luckily a 98 ( I assume is a 98 action ) is super strong!
Few years back a friend working at guns store told me that he sold a .270 and a 308 both Winchester to husband & wife the following week the husband return to the store with the .270 claiming that he can't open the bolt after he fire ! My friend use a mallet on the bolt handle and when open a .308 brass came out!!!!

You got THAT right. Probably what saved the day.

A mallet to open it? seems to me it would take a mallet to close it also.

There was an article in Shooting Times magazine years ago showing what was left of a .270 Weatherby Mag. rifle after the owner accidently fired a 7mm Rem. Mag. round in it. The rifle was literally blown to pieces, some of which were never found. The only part to survive relatively damage free was the barrel, with the 7mm bullet still firmly lodged in the throat. Seems the effects of friction, pressure and a sudden stop as it tried to enter a smaller bore had mushroomed the base creating a very effective plug.
If a 7mm bullet cannot be forced through a slightly smaller(.007'') 270 bore there's no way I'll ever believe a .308 bullet that's .031'' larger can, or a 35 cal. through a .323 bore without similar results. Nope, not in a million years.
