[QUOTE="rost495, post: 77341, member: 1768"] I've fired more pounds of 540 and some of 550 that I can recall. But only in 223 AR15 rifles. FWIW in the 223 caliber the barrel life has been appx the same as with any other powders I"ve used. Good cut barrels run around 5k, buttoned aroun 3500 for top accuracy. (mind you I'm pretty picky) On larger cases vs bore diameter I cannot comment. I can add that it does add velocity and add enough without excess pressure to allow a visible advantage in the matches I shoot it such that the cost is well worth it for me. Our cost down here was always around 20-23 bucks a pound and thats not much more than standard powder costs. I don't think its fair to compare its cost to surplus powders, since they are even less than standard. IE I bought some surplus some years back in 200 pound containers for 2 dollars a pound. Thats not a fair comparison. Jeff [/QUOTE]
