Chapter 4 of Bryan Litz book Applied Ballistics for Long Range Shooting.

NED is correct.

"A bullet always shoots slightly higher when it is fired downhill than when it is fired uphill at the same angle. The reason for this is that when the bullet travels upward, there...

Lets put this to bed guys..

1. "First, the range scaling ignores the effect of the bullet slowing down as it travels thru all the air between the shooter and the target." - Bryan Litz

Absolutely agree with this mate. Thanks.

Mate in all honesty you’d be surprised at how quick and prepared you have to be especially with Sika. Often you may get two or three minutes if that.
I’m no stranger to bush hunting but to me there...

In fairness that’s probably for another post.

My guess is that those that are relying solely on their rangefinders TBR outputs to calculate an inclined shot aren’t shooting as steep or as far as...

650y (line of site) @ 20° angle = 68" of drop

611y (TBR) @ 0° angle = 62.5" of drop

Error in mm's = 140

This is now getting into 'missing deer territory' taking other field shooting...

Using shooter I calculated the following:

650y (line of site) @ 15° angle = 70.4" of drop

628y (TBR) @ 0° angle = 67.2" of drop

Error in mm's = 81.28

Found this quote

"Rifleman's rule has another nice property besides simplicity: it does not depend on the rifle, caliber, zero distance, etc. - just inclination and distance. This allows...

I use a range finder that can display an angle.

I do totally agree with your last comment, but all that I can think of is that the ballistic app is obviously doing more behind the scenes than...

At longer ranges, you certainly need to be measuring angle accurately and allowing for it if you want to take venison home.

A range finder TBR is basically applying this rule.

When I did some ballistic calcs and compared bullet drops (in inches) using the line-of-sight distance/angle inputs against TBR/EHR on its own I found huge differences at longer ranges?

IMO - Based on the drops I have calculated comparing them, and the article Chalkeye posted about TBR, I wouldn't recommend shooting at a deer using TBR past 400m.

TBR is great for someone with a...

Yeah I think TBR is great for anyone wanting to shoot out to 400m

Beyond that IMO it's faster and more accurate to..

1. Take a 'line of sight' range and an angle (if your range finder displays...

For those that are interested I have done some calculations and compared bullet drops for (TBR distance solutions) against (line of site distances AND angle solutions)

650y @ 10° using TBR I would...

To me it’s only worth using the TBR setting if you’re running a custom turret with yardage increments or using a ballistic reticle for hold over.

Otherwise you may as well just enter the usual...

That’s a great article thanks.

Im interested in hearing from people that use BDC turrets and TBR ranges successfully at long range?

I use a BCD turret and my basic rule of thumb for 10° to 15° shots out to 600 yards is that I...
