7mm rem. mag reloading

alexdolhyj
im getting a start on making my dream long range elk cartrige before the season rolls around. one that i was thinking up either sierra game king btst 150gr, with 61.0gr of h414 powder. or the nosler accubond 160gr, with 58.5gr of imr4831 powder. i havent produced either yet, i just wanted to see what you all think and if they are heavy enough loads for 600 yards, 800 yards tops... any reconmendations would be great, thanks.

    The shot can be made but with a 7 mag you lack knock down at that range. (just my opinion of course) Those bullets are light and fly straight but got nothing behind them, Step up...for shots at that range, to the 300 Rem ultra or 338 Lapua. 180 grains is the min for shots at that distance. (Again just my opinion of course) you need knock down power! And a Bullet with a high BC that will shoot Straight. Those shots take serious dedication in the off season, And a serious confidence in your rifle.



    Edit... alexdolhyj

    Exactly. 338. pretty sure your question was in regards to the 7mm rem mag[;)] But on the other side build a 7mm STW. That will keep ya in your 7mm bullet, which aint worth nothin to me[:D] just my opinion of course



    Edit...
    +1 to Sandwarrior, Golferboy426 apparently you dont hunt the west[8D]

    not true. helped my buddy drop one clean with his .338 factory loads at 775 yards last season, one shot dropped it flat in its tracks, key is good optics and and good mathematics. any ways i did say 600,800 tops, since thats really stretching it with with the rem mag. arizona elk hunting is primarily long range, 200 yards and up, its all open land with little cover

    i was thinking that the bullets are a bit light but with anthing more that 160 gr the bullet drop becomes significant so im trying to find a happy medium

    alexdolhyj,

    Nosler Accubonds would be a good choice as well as Hornady Interbonds. I know some people don't believe it but Berger now has their new line of "thick" high BC specially made for LR hunting bullets. I don't know a whole lot about terminal performance but I've seen the bullets after they've been pulled out of a sandbank @ 525 yds. They expanded well and still held most of their weight.

    For loads, I would recommend the slower powders with heavier bullets. 160 gr.-175 gr. Here's the Hodgdon website:
    http://data.hodgdon.com/cartridge_load.asp

    And the AA website gives starting loads with AA3100 of 57 for the 160 weight and 54 gr. for the 175 gr. bullets.

    Another really good powder in 7 Rem Mag is Reloader 22. The website is: http://www.alliantpowder.com/

    It wouldn't hurt to get another reloading book and see what it gives for loads for those weights.

    golferboy426,

    What is unethical is no knowing where and how far your rifle can shoot accurately. I personally feel that for some people I know, taking a 50 yd. shot is unethical. Yes, there is a lot more challenge in taking 500-800 yd. shot on an animal but for those who practice and know how to do it. ...and, when not to take the shot... it is not unethical. Just buying a viable LR rig and going out to shoot 800 yds does not make one competent to do this. But, those who do practice and learn how to shoot at extended ranges, it is ethical.

    nobody was an overstatement, lets just say 1 in 100,000 maybe !! An this guy just by asking the question I know he can't. I just love all the braggers who say they dropped one at 500 when it was really 300 get real

    Anyone know the foot lbs available from a 7 MM magnum at 600 yatds. I am guessing it would not be consider an elk cartridge if a similar amount of energy was fired from a comparible cartridge with equal energy at 50 yards. Anyone want to do the math?

    golferboy426,

    That is of your opinion and you are entitled to it. With the right equipment, and lots of practice, to place confidence in yourself and your equipment, and to know when, and when not to take the shot, it is very ethical. And yes...it can be done on a very reqular basis...and it is neither unethical or nor outlandish. Just because you might not have what it takes to make that type of shot consistantly, does not mean that "nobody can". Why don't you tell all the 1000 yard competitors who are shooting 4-6 inch groups at that range that only 1 in 100,000 of them can do that? A good number of them use a 260 Remington, 6.5x284 or a 308 Winchester...not a 7mm Rem Mag.

    alexdolhyj,

    Todd(sandwarrior) gives you some sound advice...take heed to it. Make sure you find the most accurate load for your rifle at those distances, and the only way to do that is to shoot at those distances and collect data. You need a wind speed meter also. Very important. Learn the ability of yourself and the equipment, and stay well within that.

    You might want to consider the IMR family of powders, like IMR 4350, or IMR 7828. The choice of bullets is incredible. I like the Accubonds, and the partitions. The Hornady IB's are good, as well as the A-Max. Don't forget about the barnes bullets either. Their MRX, and TSX are outstanding, as is Nosler's new unleaded entry the E-Tip. The higher bullet weights is for efficiency in a high ballistic coefficient, and better energy figures. Energy is not everything, as long as there is enough to destroy the vitals, that is all that is needed. Shot placement, shot placement, and shot placement...did I say shot placement?

    Enjoy your new endeavor...half the fun is finding out all the stuff you need to know before the hunt.

    Best

    It does not mean that because you don't have the ability that no else can make the shot. Long range hunting doesn't happen overnight ... you have to put some serious range time and have the proper gear to go with it.

    Tell this old geezer he can't be taking a head shot on a cow elk at 1410 yards away.

    600 yards is an everyday shoot out west. i compete in the arizona desert sharpshooters in the F-class, i do know what it takes to pattern at 1000 yards. i know for a fact i can make an ethical shoot on a target that large, the vitals on an elk are nearly three times of a whitetails, and my rem mag is built rock steady with bull barrel, jeweled trigger, bell and carlson stock, and nikon 6-18x scope with tactical turrets my rig is ready, im ready i just need to concoct my round. i was looking at my cook books and i have decided to go with the 168gr berger VLD which are specificaly made for 300yards and up and dont begin to expand after 3in of penetration, with 71.5gr of magpro powder. thank you sandwarrior and all.
