In an article I read recently, was told some high speed rounds notice a reduction in accuracy at 800-1000 rounds...not sure that this would be true in this case as its NOT 220 Swift fast..

Personally feel there is no free lunch...but the beauty of this is they make all kinds of barrels..and really, dont know how many big game guns I have 1000 rounds through..with the exception of a .243 and my 300 RUM...
