Trailing DSR-1 .338 Lapua Magnum on steel from 840 meters

[kettune855]

cannot see se the vapor trail nowhere just plate moving about 0:16 . Ive shooted/sighted hundreds of rounds 7,62x53R . Maybe the camera is just plain shit or me coming blind .

@kettune855 Too bad, I can even see it on my iPhone - Look on the right lower side of the reticle - or get a better HD-screen..

srry cous, no i can't your just to funny.

[SpetsnazO8]

all those markings on the scope?...how do you know which marking means what distance?

[cazorp]

@SpetsnazO8 They are called Mil-Dots, and they are 1/1000th of a radian between them, basically if you know the size of the target you can use them for range estimation - google mil-dot for more info

[SpetsnazO8]

@cazorp oh thanks that should help

[URIZHEY]

@cazorp About the mil-dots, why nobody uses the bullet drop compensator? I think only the POS-1 from Dragunov SVD has that, and for me ( I dont know nothing about snipering) seems more easy to know the distance from the target. Just wondering here.

[cazorp]

@URIZHEY BDC's are great, but then you cannot change ammunition to one with another bullet drop, and also a different altitude, pressure, humidity, temperature etc. always gives a different bullet drop, so BDC's are static, long range shooting full of dynamic factors to consider before taking the shot..

[danthman114]

@URIZHEY mill dots and a bdc are 2 different things. you can use mildots as a bdc if you know your external ballistics, but mildots were designed to range a target with math. like what was said before bdc is good for 1 round, 1 environmental condition. and forget shooting up or down hill at a known distance with a bdc...

[cazorp]

The scope is a Zeiss Hensoldt 6-24x72, indeed its a heavy rifle and also fitted with a very effective muzzle brake, so recoil was no issue at all, you could shoot 10 rounds in prone full loads with .338 Lapua without getting any pain from it.

[siegehammer63]

@cazorp quite the rifle! Ive found that heavy recoil isn't my thing even though Im reather large, but Im pretty sure my 6.5 could ALMOST hit that plate... I just don't know if my current scope could see it :P. Great shooting, and Ive held one of these rifles in Calgary (Canada). Quite the peice of tech. As with the Zeiss Hensoldt, too. Probably a good half a house tied up in that thing with ammo included! lol

[siegehammer63]

out of curiosity, what kind of optic were you shooting through? and I know the DSR is a heavy rifle, so how did it perform in terms of recoil?

[mullaniumman29]

nice shot!

[cazorp]

Thanks, 840 meters is obviously no challenge för the .338, although windy conditions made it a bit tricky before you were on target this day..

[SpetsnazO8]

@cazorp

u said for distance u adjust the scopes elevation but what about the scope windage (horizontal) adjustment, wats that for? the elevation always made sense but the windage I'm guessing is for when it's windy. I mean why else would bullets wont to go to one side, aren't all guns suppose to shoot straight?

[cazorp]

@SpetsnazO8 Right, windage is for windage - rifle will shoot straight at zero wind, but there's always some wind and windage helps to compensate for that (shooting at 100 meters won't need any wi d adjustment, but at 840 meters with 3 mps wind we corrected about half a Mil I think)

[IndiJan1]

@cazorp Actually a bullet never shoots straight in any condition. If you have no wind, there is always the rotation force of the bullet that pushes the bullet up and to the right. This is ofc at really long ranges and the effect increases the further out the target is.

[cazorp]

@IndiJan1 the shot is corrected to the left for spin drift as well, the barrel has a right hand twist (as most rifles). As a rule of thumb, at 840 meters about 0,2 mrad for rotation is what you need.

[danthman114]

@cazorp most people would never see spin drift. but depending on what direction your shooting north, south, east, or west dictates which way it will drift.

[Annex2991]

@danthman114 that aint true heh, spin drift depends on which way the barrel is rifled

[danthman114]

@Annex2991 youre right i was thinking of the coriolis effect... lol
