Thanks oliver,
Good info on the heavier bullet, I have heard that about the 210gr with the 7mm, but hadnt heard the same with the 300wm.
I agree, its gonna be tough to hit the vitals at 1000 yards. I got one 2 years ago at 450 with my 243wssm with the a 6-18 nikion bdc scope. Its a great scope, but the circles would be a huge field at 900 yards, and the 243 wssm drops like a brick out that far. I have seen some pretty big bucks out at about 800-900 yards, that were impossible to close the distance on. I am trying to set up the 300 win mag with the same scope but with fine crosshairs and target turrets. I feel if I can get the group to shoot sub moa at 100 yards, I should be ok or close at 900. Weve lobbed hail mairys at em that far before but couldnt hit em. They diddnt even move, so i figure if i am a little off on the wind, i have a shot or two to compensate.
I think Ill load up some Bergers at 185gr and the 210s and see what i can shoot the better group with I think with the Bergers, I will be ok with slower speeds if it comes down to it too. They are suppossedly supposed to expand really well at all speeds. Generally I try to stick to the "i need to be above 1000fps" rule to get optimum expansion out of the bullet. Anyone have any ideas or info on that?
Testing at 100yards for a load you plan to shoot animals with 6" vitals at 900yrds is bad. Go put some paper plates at 900 yards, if you can wack them 9/10 shots in the flat center part, your good to go on coues deer at that distance. Otherwise, it's seriously not a good idea just to take pot shots at them at that kind of range.
Hitting the vitals at 450 yards cold bore is a very good shot, but now doubling that distance.... i would really watch out.
You said if you miss you'll just adjust for wind, well what if the wind blow the bullet back into the guts and you tear them apart? then you've just wounded a buck that will most definetely not stay around and run off to die a horrid death.
Sub MOA at 100 should be good enough for 6" vitals at 900yards? im sorry but im not catching on this logic. shoot half moa after half moa at 300 yards and maybe you'll have a chance at making a good shot, also have to account for a lot of stuff that screws with your bullet once you shoot that far (dont feel like listing all the factors...) same reason a .25moa gun at 100 is never, or extremely rarely a .25moa gun at 1000 (except on the internet

).
I think you should practice and study a bit more before you attempt to shoot a coues at that kind of range, but that's just my opinion from what you've said so far. There are only a handful of people on this site who can make shots like that, and they use thousands of dollars worth of equipment, practice almost daily, and have intimate understanding of how their rifle and load is effected by wind, temperature, pressure, cold bore vs fouled/hot bore etc...
Hope this helps,
Oliver
