[QUOTE="BallisticsGuy, post: 1589045, member: 96226"] My Coach's 6XC match load runs around 2800 with a HBN coated 115 DTAC. It's kinda pokey. He's up around 1800rds on the barrel now and it's starting to throw flyers. We're putting it through one last match and then pulling it and putting the new one one. My .243AI load ran 3200fps with 115's and made 1300 before I was beyond mag length on a loaded round. It still groups great though. I've since replaced that barrel with a 6XC running 2980 with HBN coated 115's. Fast 6mm's are THE ticket for when you have to spot your own shots. Recoil is super low even when you're running them sick fast. If you don't need that then there are definitely barrel life benefits to be had in a less overbore setup. I personally like 7mm. Bullet weights around 180gn can get BC's in the very high .600's, actually nearer to .7 than .6. Pushed to fairly modest speeds they have a great supersonic range and the extra mass makes for a nice whack on the target so hits are easier to hear. My 7mmRM is absolutely boring to shoot under 1000yrds. [/QUOTE]
