    Matt, there's always a limit on how far you can shoot. First an foremost, your ability is the most limiting factor, followed closely by the laws of physics. What speed are the 140's traveling? What type of bullet? What is the intended target? Are we punching paper or hunting elk? Definately need some more intel to answer this one,

    i now live in az so i would say elk is a possibility if i get drawn i know the 140s are enough for couses deer and antelope. i guess my question is am i limited on killing bigger game with the 7mm at 500yds or farther. i shoot pretty tight groups with it at 400yds now. factory loads are what i use so i can shoot a variety of different loads if the 140s arent heavy enough. i hpoe this makes sense

    Shot placement, shooting profficiency, understanding wind,weather and atmosphere are truly the key factors. A person who knows how to shoot his 243 can kill a deer easier than someone who never learned to shoot his magnum (not meaning you, just saying), if that makes sense. for 140g I personally would use a barnes loaded bullet, perhaps a tipped TSX or a regular TSX. The tipped have a sliiiightly better BC but both will do the job. Here again is where the shot placement will be key. The higher BC bullet will have less atmospheric interference. When you said you were getting tight at 400 yds was that on flat shooting ground, or angled multiposition shots that you have practiced in the field at various ranges under various wind/temp/weather conditions? These are all things to be considered. If I were you, I personally would look to go a little heavier on the bullet, YES the barnes will keep nearly 100% of their weight but at the long range you might not have the KE to really make that 140g bullet shine on such a large animal. I hope this info helps and I hope you bag a biggin. Make sure you post pics buddy. If there is something I have said wrong someone please feel free to correct me so I can learn more.

    There's a whole lot of variables and lots of questions that need to be answered. Like stated before: your ability, the definition of a 'pretty good' group, the max range you want to shoot, your set up and optics, etc., etc., etc.

    MATT- I live in colder part of az. welcome. it snowed 8 inches and i am shoveling. the 7mm mag is a great long range round. the 140 out to 500 or more yards is very good. the gun and scope are more important than caliber though. they determine how far you can shoot. you will have to go shoot your rifle and see what its capabilities are. shoooting distance take some practice that is why most(99.99%) reload. you can get a coues deer permit every year if you want the others you are probably going to have a wait. it took me 27 for bighorn. i have 19 for antelope and it took 17 for elk, 14 for mule deer. both of my 7's shoot 140 bergers and accubonds into less than 1/2 inch. there are f-class matches in the valley if you shoot those matches it will help . i do it because i get to shoot more than one shot a year. it was good weather yesterday and i won. look on desertsharpshooters.com for calendar. roniflag

    While I agree with previous posts on needing info on your capability, intended target/game, optics etc, etc... I want to address your choice of bullet and long range shooting.

    In 7mm the 140 is about the lightest bullet and has the lowest ballistic coefficient compared to the 150, 162, 169 and 180grain choices. Your 7mm mag can certainly push the 160grain bullets with some decent velocity.

    That said, my recommendation to you would be to see if your rifle will shoot accurately a heavier bullet.

    i have a kenton knobb on my scope . with a 140 berger i am within an inch or so of my 168 load out to 700. it does have a bit more wind drift according to the charts.

    Missing one more item gentleman the bullet proformance and I am talking velocity, a min of 1200fps to kill at long ranges. We might be able to shoot 1500 yds but a bullet doing 600 FPS is not going to kill nothing.
