Thread: Acceptable group size at long range ?

I'm not a LR shooter but I reckon if it's windy get closer.... it affects the the bullet and can help in sneaking in closer

I'm an internet expert. I can tell you all about the internet. You see, it's this thing for looking at pornography and arguing with people about retarded shit

R93 I would really love to know what cartrdge you use that only has 1inch of wind drift at 100 yards in a 30 knot wind.

As best as I can tell the 7mmWSM shooting a Hornady 162gr Amax with a bc of 0.625 would have to achieve 4000fps and it would still have a wind drift of 1.1" at 100yds in a 30 knot wind. At 1000yds this load would only have about 138" of wind drift which is approx 70" better than the same bullet at 2950fps. That is a real advantage.

Tussock I have no idea what m/sec is so looked it up and found out that 3 m/sec = 6.7mph

I also found this
Beaufort Wind Scale Windspeed
in MPH Description - Visible Condition

0 Calm smoke rises vertically
1 - 4 Light air direction of wind shown by smoke but not by wind vanes
4 - 7 Light breeze wind felt on face; leaves rustle; ordinary wind vane moved by wind
8 - 12 Gentle breeze leaves and small twigs in constant motion; wind extends light flag
13 - 18 Moderate breeze raises dust and loose paper; small branches are moved
19 - 24 Fresh breeze small trees in leaf begin to sway; crested wavelets form on inland water
25 - 31 Strong breeze large branches in motion; telephone wires whistle; umbrellas used with difficulty
32 - 38 Moderate gale whole trees in motion; inconvenience in walking against wind
39 - 46 Fresh gale breaks twigs off trees; generally impedes progress
47 - 54 Strong gale slight structural damage occurs; chimney pots and slates removed
55 - 63 Whole gale trees uprooted; considerable structural damage occurs
64 - 72 Storm very rarely experienced; accompanied by widespread damage
73+ Hurricane devastation occurs

At last, something useful in this thread.

My 338 drifts less than an inch in a 30 knot sidewind @ 100 yards. 300gr (.450 g7 BC) @ 3,275 fps.

That's pretty impresive so is that the 338 Lapua Magnum or some other 338? Also which projectile are you using?

Berger Gen 2 Hybrid, using custom BC as the .420 BC means it will shoot high. Chey Tac case (Greg Duley's 338 Lunatic)

Not bad for a yank comedy alright. I hear Peter's fights with the chicken are coming to an end??????

Not the chicken fights! Someone told me they do them because it's cheaper haha


Dad, what's the blow-hole for?
I'll tell you what it's not for, son. And when I do, you'll understand why I can never go back to Sea World.
