This is a test:

Quick...... whats the amount your bullet will drift if you have a guesstamated 20kph cross wind at 400yds.?

The wind is angling from left to right into your face at about 30 degrees.

State your caliber, bullet weight.
No crunching either

, from the hip as it might be, or at least from your handy range card, or equivelent.

Trev. You got the popcorn on?
I'll bring the bevi's.

This could get fun....especially for all those self-proclaimed long-range experts......

Huntnut · #3 05-26-2007, 02:07 PM

Well I'll be the first to be ridiculed. Shooting a 300 ultra with 200 gr. accubonds I'll guess 5 inches. Last time I shot that far with this combo and in about half that wind I got approx. 2 inches of drift.

Dick284 · #4 05-26-2007, 02:29 PM

Sorry Huntnut:
But you miss guessed the wind by 10kph, and it's actually 40 degrees towards you, your guess on wind drift just went OTL, and to top it off the animal you were aiming at happened to take a 1/4 step, and you now have a gut shot animal.(Sorry to highlight you bud, these misconceptions need airing)(PM sent with apology)

This illustrates the hazards of long range shooting.
Too many variables.
See what sort of ethical quagmire we enter into if we choose to take these kind of shots.

I wonder how the self professed long range advocates are going to respond to this?

roger · #5 05-26-2007, 07:09 PM

what are we shooting at? a paper target or a book whitetail buck standing over a scrape? or a meat doe?
either way...get a faster pellet and ditch those AAA battery sized bullets,

stir that pot before it burns!!!

Roger, ya dont understand. A smaller, faster bullet, aint whats required to dispatch animals at extended ranges. You want to ship those big bullets. By the way, a bigger bullet bucks wind better than a small one.
Dicks right, and what if your shooting across a ridge top, or even two. The wind could be hitting that bullet from the top, bottom, sides, you cant tell, and what if your bullet hits a blade of grass at 300, while its crossing over the top of one of those hills. Whats the ambient temperature??? Did you do all your rge work in the summer, when the rds are sitting in the sun at 25 deg C. Now your little cheat sheet on the stock aint gonna help one bit, cause its 10 below, the rds are colder, the barrel has contracted from when you factored all this in the summer, and you are in a quick situation. You are in a field position, and your about to rush the shot. Right, or am i wrong. Scary stuff. And its awful real, cause when you take a shot at something, theres no taking it back, good outcome, or bad. long range = long odds.

keep a strain on er. pack.

Dick284 · #7 05-27-2007, 01:46 PM

Zackley my point Pack:
Did you evaluate your hunting loads in August, or in February?(fits better with Nov. BTW)
Did you Chronograph them?
Did you check your ballistic calculations against real world ballistics?
Has the Humidity changed?
Has the Baromatric Pressure changed?
As you stated earlier how bout elevation changes?
Have you ever verified you laser range finder, bumps dings and reflective interference all affect it.
And of course how do you measure the wind speed?
I like your analogy about long odds.
I guess some people are more willing to gamble than others.

Funny how no one has tried to jump in a plead their long range case.

Not to worry 50BMG: there have been lots of threads on this subject, and most likely many more to come.
I applaud your lack of desire to harvest game at long range.
But also open to interpertation is, what is long range hunting?
This is whaere the heated discussions arise. And i don't quite care what an individual defines it as, just as long as they are responsable about it.

who needs long distance shooting in alberta.The farthest shot this year was under 200 yards at a moose no less.

Andrzej · #12 05-27-2007, 10:37 PM

Every year I shoot a few rounds at 500 meters and most of those targets have bullet holes just below point of aim so either I am shooting in ideal conditions or lateral wind deviation is overestimated...
I used to shoot 3006 with 50 inches drop at this distance...steel perfect under point of aim now 21 inches drop with 7 STW.
I have fired 7 STW at 300 meters in very windy conditions 2 inch group still have this target...no different point of impact than without wind.
Are you looking for excuse for bad shooting... blame wind...

Before you make a statement like that-find out whan ballistic coeffiecnt(sp) means. Then look at the BC of a 200gr 30cal accubond versus a 7mm 140 gr.

mjmalberta · #14 05-28-2007, 01:18 PM

well what if i was useing my 338 laupa bullet drift is no where near the same as a 30/06 for example

Stinky Coyote · #15 05-28-2007, 05:57 PM

I'm not a self proclaimed expert but i shoot my tikka .270 and Cz American .204 to 500 yrds playing in field with burris ballistic plex reticle and getting the height right is no prob but i've limited experience with either of them with heavy crosswinds.

I shoot 130 gr factory fusion ammo in .270 at just over 3000 fps and the 32 gr v-max factory hornady a little over 4000 fps.

My guess would be about a 8-10" for the .270 and 5-6" for the .204.

I've never run a calculator or anything so have no idea. That'd just be my guess if i was in the situation at the moment...so this is a real as it gets answer. How close does your calculator put me?

P.s. I'm just warming up to this longer distance stuff and only do it to practice and be prepared for the just in case hung up coyote etc. My furthest coyote to date is 285 yrds with the .204 (direct hold) and then got two at 250 yrds and one at is 235 yrds...the rest of coyotes are generally under 130 yrds and big game furthest with gun is about 125 yrds.

Dick284 · #16 05-28-2007, 06:30 PM

Better get acqunated with your equiptment Stinky
Just under 12" drift with the 204
And just over 7" drift with the 270.
That's off a ballistics program, sometimes the real world will be difrent than computer simulations, but not by all that much or so I've found.

Stinky Coyote · #17 05-28-2007, 08:20 PM

Ha. Did alright on the .270...i had an afterthought on the .204 and thought about editing to the same as the .270 guess but still wouldn't have been enough. I'm happy as i've never tested it much in the wind and planned on really dialing in the .270 this summer to 600 so it gives me some starting points. Thanks. Interesting topic btw.

roger · #18 05-28-2007, 10:03 PM

257wby 100grains, 3550fps
im guessing 3" drift with 10 " over POI when sighted in at 2.75 at 100,

hi gentlemen, As you suggest, long heavy bullets start to really BEGIN to shine at these ranges and beyond. that is not in question, Nor was ther any mention of dispatching game. However, Dick is asking the shooters if they can 'feel' the shot based on experience in the field or the range under these circumstances. SD, Bc's, velocitys, etc etc have marginal effect on the final outcome when it comes to a hold over/crosswind estimation billiard type shot (without ample practice) as described.

at least thats how i read it.
to further my theory/proposal/observation is if a bullet is travelling twice as fast wouldnt the effects of drift be half as much, based on the fact that outside influences have less time to act upon it?
