Both you guys are right.
It was happening when the gun got REALLY hot. Not 1 round every 3 seconds.
Well it is up to you all.
This is the problem I have with steel cases.
1. The case is covered in laquer to prevent it from rusting. The laquer melts when the round is fired and coats the chamber of the gun. This mixes with powder fouling gumming up the chamber and bolt.
Just because you shoot slow doesn't mean the gunk is not building up. And how can you be sure you cleaned all that crap out at the end of the day?
2. The steel case does not expand when the round is fired. Therefore the camber is not completely sealed. Powder and jacket fouling is free to further contaminate the chamber and action.
3. Steel cases are much harder than brass. Steel on steel contact during the violent cycling of the action will enevitably excelerate wear on the bolt, chamber, extractor and ejector.
4. The expantion of brass cases 'grabs' the sides of the chamber when a round is fired. This diminishes the force applied to the bolt of the rifle and bolt lugs. Since the steel cases do not expand much the case can not resist the force of the round firing. The bolt lugs contain the entire force of the explosion. This cannot be good for the firearm.
90% of all the times I have seen someone having to beat open the bolt of their AR, or pound out a case with a cleaning rod, the culprit was a cheap POS steel cased round. Beating on a firearm is not the best thing for longevity IMHO.
So, you can use those if you think YouTube is on it. Im just saying none of my guns will ever see a steel cased round.
I don't believe in saving on cheap ammo, and then, perhaps, spending a whole lot more fixing an expensive firearm.
Good luck.
