sorry if this is is the wrong place. seemed like the most reasonable

copy and pasted (rough math would put that at about 65 MOA for wind drift at under 1k) what kind of wind would you have to have for that? did not specify projectile just said 338 Lapua Magnum

By contrast, much of the U.S./Coalition urban sniping in support of operations in Iraq is at much shorter ranges, although in one notable incident on April 3, 2003, Corporals Matt and Sam Hughes, a two-man sniper team of the Royal Marines, armed with L96 sniper rifles each killed targets at a range of about 860 metres (941 yd) with shots that, due to strong wind,<span style="color: #FF9900"> had to be fired “exactly 17 meters (56 ft) to the left of the target for the bullet to bend in the wind.”</span>

Very interesting. Playing with some numbers using JBM, a 300 gr .338 Scenar at 2800 fps, 5000 ft altitude, etc., etc., would need approximately 42 MOA windage at 950 yds in a <span style="font-weight: bold">100 mph</span> wind. FWIW, 100 mph is the highest wind value JBM allows. Seems like that was either a typo, or those fellas were dealing with a pretty stiff breeze (LOL).

And I thought the wind blew in Wyoming.

Bet the wind that moves a 338L 65 MOA would make for some fun off hand shooting.
 
Re: Ever heard of anything like this??

ya i did the same thing and finally put in 131 MPH wind and it was a perfect hold for 300gr Corbon factory ammo. And thats Full value 90 degrees!!!!
 
Re: Ever heard of anything like this??

I think it was elevation and not windage. Anyway, I've seen another account with the windage as posted by the OP with elevation of about 35 feet. Maybe it is backwards.
 
Re: Ever heard of anything like this??

I thought the L96 was in 7.62 and the L115 was in 338LM. I know the L96 shows it can be chambered in 338Lm but if you do the math for M80 941yds with a 58mph wind at 90deg that will require 68.2 MOA to connect. At least with the numbers I have for M80.

I figured the 56’ as 56*12=672 To give inches of total deflection.

Total drift divided my moa at 941yds 672/9.85227=68.207 moa of deflection.

Then just upped the wind on my calculator until the moa came close to 68. 58mph wind = 67.7moa and 59mph = 68.8

My calculator for my 338 with 100mph wind only shows 47.2moa for that distance.


EDIT 68.2.3 to 68.2
