How many rounds can you shoot through your typical rifle barrel?
The other day at work I had about 1000 rounds to burn. The first 10, 30 round magazines I shot just using rapid trigger pull. My barrel turned extremely blue/purplish, and was really hot. I grabbed another weapon, shot about another 9 magazines on burst, changed weapons and finished up the last of the magazines on a mix of burst and semi. I know it didn't hurt to change weapons but just for future reference how many rounds could I throw down range before it becomes hazardous to the barrel? I know when people get issued .50 cals, 240s and the 249s that you also get issued about another 2-4 barrels to switch out.
