    OK. Next Spring I will be having a new rifle built. Busy now putting all the parts together. I'm torn between a .243 AI or a 6mm AI. Which do you think would last the longest shooting mostly max. loads? The barrel will be the best I can afford, (probably $250-$400).

    Small bores and high velocity kills barrels.

    As I recall triple-base powders have faster throat erosion too.

    I think the difference is likely to be negligible. Both are going to toast the barrel throat, the 6mm will likely do it a tad faster as it hold more powder. What were you planing on using the rifle for? If its going to be a hunting gun, then i doubt youll ware it out anytime soon.

    I have heard concerns about barrel life, throat erosion fears all of my shooting life, I have yet to see one truly "shot out" I have a 17 Rem with about 2000 rounds through it, and it will still shoot 1/2 moa, my .220 Swift, supposed to be the biggest offender of all has over 1000 rounds through it... still in the money... I would not be overly concerned... and I am a sticker for records and accuracy... Just go with a good barrel to start, make sure that you have a GOOD Gunsmith set it up.. Douglas, Shilen, Lilja, are all good barrel makers.... Can't speak for the others...
