Thread: Range finder- what's everyone using and why?

I point my rangefinder at stuff, pop what it tells me into strelok and pull the trigger and it hits stuff out to further than I'm ever going to need. That's all I know

The difference will likely be minimal. I might have to have a play and see what I come up with. Logically if shooting up a component of gravity is slowing the bullet along it's trajectory, while if shooting down that component will actually be accelerating the bullet along it's path.

Most times I've encountered Gadget you'll have to hold low whether it's up or down, so long as a its a decent distance and the angle is steep.
Dialing you'll need a proper angle to get it right, once again if the distance is longish and the angle steep.
Horizontal range is what your looking for
Better shooters than me will come along and explain it properly I'm sure.

Pretty sure Greg Duley looked at the TBR vs actual distance and angle of shot. He found after running it through a ballistic calculator there was no real difference. Maybe if you are pushing 1000yds it might, but not at most usual distances.

Fair enough
However last xmas up the Rangitata I made a dialed shot fairly steep up hill at 503 meters and laid it underneath the Tahr,
Next shot using mil reticle down two maybe three can't remember, ask Gimp he was there spotted, took it out .
Probably just bad shooting
I see shots go over wallaby at 6-700m when the angle is steepish and I haven't sorted it properly.
I tried the Ballistic curve on my 1600B
couldn't hit shit over 400m

Watched @Philipo take a wallaby with his 6mm 204 at a ranged 600+ at a gentle angle
Dropped it DRT.

Just put the battery in the Sig Sauer kilo2000 and had a play. Pretty impressed.

An OK photo of the view.



Ranged this tree from a little further back at 2003 yards but was getting difficult to hold steady.



Photos a bit tricky holding the phone camera lens behind the ocular of the rangefinder.

It that Meters or Yrds GM.?
whichever, it's quite impressive.

Yards.

Best article ive ever read on it, basic rule of thumb. If targets at a 30 degree angle, treat the range as 90%. If target at 45 degree, treat it as 70% range.
Has only let me down shooting 900m at steel, small angle made a big differenec

Hi, I thought I'd share my 2cents worth.

The attached pic is a photo of one of the range cards I use for my 7RM. It gives the come ups for ranges out to 800 and corrections for angles. Wind and longer ranges are on the reverse side. I used a combination of ballistic apps and software to calculate the numbers and input them into a spreadsheet.

For example,
Take a line of sight range of 600. On the flat the comeup is 10.7 MOA. If the shot angle is 25 deg (up or down) then an additional correction of -1.5MOA is applied. 1.5MOA at 600 is roughly 9 inches.

This is what I have used, and I know there are better ways out there, but it works for me. The pen shows the rough size of the card.

Cheers,

Oh yeah, I forgot. I use a Leica 1600B as it gives me line of sight angle and has fantastic optics.

I bought this on special for $123 NZD delivered, not on special at the moment but worth keeping an eye on or looking for another seller with the same product:

Seems pretty good. On a clear day it ranged to 1250m. The ranges it gives are accurate comparing to maps/satellite data. Overall very happy, will see how it lasts.

Range cards and ballistic tables are all good until one day you're hunting at 30 degrees Celsius at sea level and then the next day you're at 1200 meters and it's -7 degrees. Those sort of variables really start to make a difference at extended range

Could not agree more. Hence I have a few different cards set at different altitudes.I just pick the one relevant to the area I am going to. Have had some good successes. Also I use shooter app on phone when required for longer shots.
A range card is quick and doesn't require batteries.

Both! I believe the unit itself houses 12 preset ballistic curves (whereby you just select the pre-programmed curve that's closest to your bullet's trajectory) and, you also have the ability of going to Leica's online website and using the real ballistic software to program your SD card to your bullet's 'exact' (or pretty close to it) curvature. If that helps answer your question?
