    What do you guys think is the real world max effective range for 7mm-08 w/ 22" barrel for deer, using the most effective bullet for the long range?

    I use the 120gr ballistic tip and have made shots past 500 yards ( the ballistics show it
    is good for deer beyond 600 yards) with 1000 ft/lbs energy @ 650 + yards.

    The 7/08 does well with 120s, 140s and 150grain bullets.

    Elk should be taken no farther than 350 yards with the little 7.

    Hmmm.
    The bull elk I shot last year at 530 yards didn't complain about the 7mm08 140 grain sierra game king.

    Just for fun, I loaded up some 180 Bergers to try out in my 7mm-08...Can't wait to see if they'll group. :D

    In the end, the max effective range is going to be determined by your bullet's velocity, BC and minimum expansion velocity. Run the numbers through a ballistic calc and see what it tells you. Padding a 100 fps or more isn't a bad idea.

    I'm having one built right now to shoot the 150 long range accubond. If I can get 2850 from it, I will still have 1000 ft/lb of energy at 900 yards.

    Every book I read tells me that I should be getting 2850, but for some reason I only get 2640 on the chrono.
    Varget & Sierra game kings.
    I have tried reloader 19, but I don't get any accuracy.

    What barrel length do you have? The books most likely are shooting longer barrels.

    22"
    A lot of the books, and other forums are saying they are getting that velocity with a 24" tube.

    Certain rifles are just slower than others because of chambers and barrels mostly. Brass can also make a difference as well as the primer. Bullets with smaller bearing surfaces are also faster because the rifling grabs less of it which equals less friction. It could be any of these factors, being 2" shorter than their barrels also doesn't help either.

    I'm going to be using Re 17 or Power Pro or n550. These should yield higher velocities than varget.

    Must be the gun. I use 42 grains of varget, any more than that and my accuracy goes away.
    I'm happy with the load anyways, and have the gun figured out to 600 yards.
    A little more speed might be a nice addition, but it's so hard to find powder, I'll stick with varget.
