[QUOTE="243yote, post: 367071, member: 16909"] OK I rechecked all my cases that I reloaded and the ones i did not after the suggestions i got back. Looked closer at my problem. Step 1: checked new never fired brass along its length with a straight edge. NO deformation or bulging. Step 2: Check once fired brass with straght edge also. Noticed that it had a slight bulge in the area where the other brass had cracked and one had seperated- the stuck case. Also the once fired brass was before the case seperated and got stuck. And before any sanding was done. Step 3: Checked reloaded brass and noticed same bulge in the same area with a straight edge. Also looked inside brass with a flashlight and noticed that the bulge was uneven. More on one side than the other. Also used a bent paperclip and could feel the deformation more on side just like i had seen. Step 4 : Scratching my head?????? Step 5: Looked in the chamber of my gun with flashlight. Saw the sanding marks where i had taken down burrs with sandpaper from stuck case removal. Also noticed while looking inside that there was a low spot in the chamber which was NOT TOUCHED by the sanding. It is in the area where the brass was bulging. I can see the chamber straight on because the gun is a break open action. I dont think you could notice this with a bolt action? It was NOT a shadow from the light either. I could definately see the low spot. Step 6 : Wondering if when the chamber was cut that some how the the tooling was crooked? That would be the only way that i could think of how that low spot was in the chamber? Step 7 : Called H&R this morning and they are sending me a shipping label so i can send it in for them to take a look at the gun. Explained to them what i had found. will keep everyone updated. Measurements are as follows : New brass never fired - no bulge 11/32 from bottom of case Once fired brass - bulge 11/32 from bottom of case shot before stuck case happened Reloaded brass - bulge 11/32 from bottom of case Rifle chamber - measured where low spot is guess what 11/32 from the end of chamber Caliper measurements 11/32 from bottom of case new never fired brass - 0.463 once fired brass - 0.471 reloaded brass - 0.471 All the brass that did have a crack, cracked on one side and then the crack almost goes all the way around. Also the ones that did crack all had flattened primers except for one. Some brass that day did not crack but you can see a slight hair line crack on the them. Also looking inside of them they show the bulge is more on one side that the other. Also looking at the inside of the once fired brass it also shows a bulge on side. Well hope this clarifies it some.
