Sighting In

For 40+ years, I have used +3" at 100 as my standard for all big game rifles. This will get a MRT of 4" or so with some rifles, but I have never had to think about the implications of that, since I am used to the setting, and comfortable with it. With this setting, if I have to hold above the hairline of an animal because of distance, I ask myself Do you really need to take this shot, or can you get closer? Regards Eagleye
 
I do the same as Eagleye. (two old guys, go figure!)
Curious that many fuss about flat trajectories, and don't sight in to take maximum advantage of it.
 
Yes Pat, some would say that we are "stuck" on some method or other, but it's really hard to argue with success, right?!! Once you have worked with a successful system, it's easy to keep using it, unless....someone can prove they have a superior system for you. Whatever works for an individual is fine, but I just log into my memory the figures, not from a book, but from actual shooting, and go hunting. This sytem has brought me so many one shot kills from <40 yards right out to 400+ that I cannot see changing and messing with my mind, small as it is ;) :D :D Regards, Eagleye.
 
I am shooting a 270 WSM with a ballistic plex Burris.

I zero dead on at 100yrds.

The ballistic plex grids make all my yardage adjustments. Mind you it takes some practice to do this and it is easier with a flat shooting round.
 
Just sighted my 338/378 this weekend. Just under 2" high at 100, 2" low at 300. Then it goes up a little. Just kidding , thats a 210 TSX at 3450 fps.

Pretty much the same thing for me.
However, I do have the advantage of an MP* recticle and turrets if i so choose.
My irons are zeroed at 200 yards.

I likes to sight my big huge Magnums in for 600 yards 'cause then I can shoot as far as I can see with them high powered scopes on my big Magnums :D :dancingbanana: Yup, I got my elk with one shot at 700 yards and I aimed dead-on with my big magnum. Yessireee :rolleyes:
 
dddddddddd

???????????????????????????

it was good reading............
 
My Big Game Hunting rifles Zero'd for a 100 Meters.
I don't shoot much past 300 anyways and most are well under a 100;)

My Varmint/predator rigs I like to zero for 200 Meters:cool:
 
I used to sight in 3 inches high at 100 yards. However, ever since I started shooting competitively, I've settled on sighting in for 200 metres. I find that a very practical range. If I was ever required to shoot way out there, I'd be more prepared with this arrangement because I know how many minutes I need to come up from a 200 zero. The .308 loads I use in competition (155 BT Match bullet at 2980 fps) are actually quite similar ballistically to my .30-06 hunting loads, so I'm fairly confident of the amount of elevation needed for any reasonable shot beyond 200 metres.

For shots at big game out to 250 metres, I can hold dead on. After that, elevation becomes a factor and accurate range estimation is CRUCIAL (not to mention wind reading in a situation where there are no flags and no spotting scope set up to read mirage).
 
BC Bigbore, thats pretty impressive shooting. One shot at 700 yds. Personally I won't take shots past 400 and consider anyone takeing pot shots at almost double that to be somewhat unethical.

Unless you have one of them big huge maganums with a high powered scope lol
 
Sight in

I posted the trajectory numbers for my 338/378 because I'm so impressed with it. I don't think it turns anyone into a 1000 yd shooter. It will definatly help with wind and holdover but won't really change the way I look at long shots at game. I normally sight in for 2-2 1/2" high at 100 and figure 6-9" drop at 300 yds depending on the cartrige being used. I'm lucky and have a flat 300 meters at our range. All my hunting loads are checked for actual drop at 300 before going into the field. By the way my biggest hunting scope is a 2.5 x 8 Leopold.
 
I usually just shoot at a empty case of beer at about 50 yards or at the back of my truck (away from the gas tank) :runaway: if i've already thrown the beer box out. If that works OK Then I just figure out what I should hold at around 200 yards or so :confused:
 
Great thread T/B.
I am a fan of multi reticle scopes and range finders for hunting. Practice and load developement are the keys to making the most out of these scopes.
I feel I am better equipped to make accurate shots at various ranges now with my firearms using this technology.
