    I'm finally getting around to assembling a 6mmBR for more practice. After 850 rounds out of the 270 Allen Mag almost any other smaller cartridge is worth a try.

    However, much more compensation for wind will be needed for the .3 or so bc difference.

    Roy I have only shot this rifle to 1000 yards on two different occasions. Well actually my wife was at the wheel one time.

    Here are some numbers.

    MV according to exbal is 2773 with a 107 SMK and a BC of .527 This is over a moderate load of RL15.

    Velocity at 1000 is 1466 so she is still super sonic but the energy is down to 510.

    My zero is at 140 yards ( i did this because I shoot ittle gophers and I like the point blank tradgectory with this zero)

    Come up is 29.25 for 1000 yds here at the house at 4000 ft.

    Wind at 1000. With a 5 mph full value you need 3 moa and with a 10 mph full value 7 moa.

    I have taken a yote facing me at 653 yards and the bullet exited under his tail with a 1 1/2" exit. I was impressed with this and plan to take a speed goat out to 700 with it this fall.

    I installed a JP brake with the thought I wanted to see gopher hits at closer range. It works and makes shooting varmints a hoot. My wife is just starting to shoot. I dialed her in and turned her loose on the 1000 yard target one calm evening. She fired 3 shots at the 2 1/2 " orange dot. One was a hit the other two were about 3 3/4" off.

    Jeff

    Note: I had posted the load wrong...!! it is with RL-15 not 19 I changed it now.

    Lots of good advice! Another good cartridge would be the .260 remington. Everything stock, low recoil, good bullet selection, and relatively easy on barrels, good accuracy.....Rich

    Another vote for a 308. I was faced with this a while back, I had a 300 WM that shot great but didn't last as long as I would have liked. After it was shot out, I made plans to rebarrel it in the same caliber and bought a 308 for practice. The cartirdge is fairly inexpensive to shoot, extremely accurate, and easily capable of 1,000 yd + shooting.

    Re: What caliber for LOTS of LR practice

    I was in same boat, getting ready for a private training session and was wondering what to take besides my new 338 edge. Everything else i have is barrel burners so i went with a standard factory 243. I have the Berger 95 vld shooting good with a nf mounted on so i will be taking it as the second gun. When i return i will use it for a lot of practice and if it burns, so let it be i will re-barrel it.

    To the OP I'd take a look at your friends ballistics tables for the rifles he has now and try and match those ballistics as closely as possible with smaller caliber. This isn't always possible, but with a little research you should be able to get pretty close. Setup the rifles as close to the same as possible and shoot a lot.
