[QUOTE="rost495, post: 58037, member: 1768"] A 223 is not a barrel burner for sure. But since I shoot thousands of rounds of 223 a year, we took a look at one particular style and brand of barrel. Then looked at barrel life vs what others were shooting. Between Varget, 2520,RL15 and N540 and N550 I could tell no practical difference in life. Maybe 500 rounds max difference but it was not repeatable enough to say for sure that it was caused by N500 series powders. One thing I do know in 223 is that N500 likes to be driven to the edge before it performs well enough for me to be happy. FYI though I've gotten 4500-6500 rounds of life in cut barrels in 223 I've never gone more than about 3500-4500 rounds in buttoned barrels and remained happy. Thats with all kinds of powders. And then what happened to the thought that ball is less damaging on the throat area, but burns up the middle of the barrel? Could never tell one way or another. Just shoot what works is what we would do. Jeff [/QUOTE]
