[QUOTE="Steve Shelp, post: 23607, member: 22"] Tim, I use this concept on my 1000yd HG competition rifle... 2 barrels, 2 bolts = twice the fun. The calibers are 6.5x55AI and 338 Lapua Improved. The 6.5 case looks VERY small inside a BAT 2"x10" action but the feeding is fine and ejection isn't a problem. BUT this is a single shot setup. If your talking about a magazine feed rifle with such drastic differences in cartridge length you may end up with feeding problems without some other special considerations in magazine length, feed rails, etc. One drawback is if you get multiple barrels (meaning more than 2 or 3) is keeping a good zero point on your scope. If you have a top notch scope that will repeat the clicks exactly everytime then it is not a problem. My 338 zero is set to zero on my Nightforce elevaton turret and my 6.5x55 zero is 3 1/8 up at 100yds. This has repeated so far when I've fired these at 100yds. But if you had 5 different barrels then that's a lot to remember and your windage could vary a lot also. So you can see the importance of repeatability in your scope unless you plan on rezeroing everytime you want to shoot. Steve [/QUOTE]
