SIGHTING IN

[thegamehunter]

I got a 300 WSM and using a 180 grain bullet. Range is only 100 yards. Where should I put the group to be zero'ed at 200??

[nchawkeye]

About 1 1/2 inches high at 100 will put you in the ballpark...

That being said....with long range gun like that I'd be more inclined to go with 2 1/2
to 3 inches high, incase a longer shot presents itself...

[wi_buckstomper]

id say around 2 in high.

I also think about 2" or so, but listen to what Hawkeye said. If you sight in 3-3 1/2" high at 100, you will be 4+ at 200, 0+ at 300 and somewhere in the neighborhood of -10 at 400. This is an excellent long range setup.

Tell me the bullet your using and the velocity and I'll run it thru a trajectory program I have. If you don't Know the velocity, tell me what your told it is. Bullet type, spitzer? Give me that stuff and I can get you in the ball park real well.

does the box show any ballistics info, some do

This will get you in the ball game. Got 2950 fps (just under max Hornady) using a 180 gr spire point.

max point blank range 319 yds
max point blank zero272 yds
offset @ 100 yds +3.3"

Bullet path:

125 yd +3.8" 2676 fps
150 yd +4"2623 fps
175 yd +3.8" 2571 fps
200 yd+3.4" 2519 fps
225 yd+2.6"2468 fps
250 yd +1.3" 2418 fps
275 yd -.2" 2368 fps
300 yd -2" 2319 fps

To figure energy: Vel x vel Divideby 7000 devide that by 64.32 multiply by the weight of the bullet.
ie: 2950 x 2950 = 8702500
devide by 7000 = 1243.2142
devide by 64.32 = 19.328578
multiply by 180 = 3479 ft lbs energy

Try the figures I gave you above, I'll bet they are awful close. With the figure's Winchester gave you, you have a 100 yd zero and50 fps more velocity, that won't make much difference over 300 yds.

The price of that ammo, I sure hope you have a lot of money or are taking up reloading! 30-06 ammo cost's about 1/4 the price and kill's animals only a bit less dead. I hadn't realized that stuff cost that much!

If you can find someone with a cronograph, you'll probally find out the vevocity Winchester gives is not quite right. To many different thing's effecting it.

Well the general consensus is an inch to an inch and half and some even say that if you have a magnum caliber that your zero at 100 will be the same at 200. From what I've witnessed a 300 Win Mag do zeroed at 100 yard shooting range do to a doe at 210 yards was about 3 inches below the heart with a well aimed shot from an extremely accurate rifle.
