Does that mean you're calculating your BC's using 150yard data and extrapolating beyond to build your drag curves and get your G7 and drop values? Or are you taking drop data and backing it into your computer to give you a BC?


Pretty much that is it.

Taking velocities at face value from the LR I've found that the BC's advertised do not always jive with the ballistic calculator. This assumes correct inputs for atmospheric conditions as best as possible (the Vortex calculator is good for that when you know your position).

Testing reveals that some bullets do not actually fall to the POA as predicted in the calculator (tall test verifies scope correction factor).

Ultimately I take the data garnered in the field and 'back' it into the program.

Many times using Litz's BC's things work out as come ups are as predicted.

I think what is skewing my results on occasion, are a combination of, velocity too slow, rate of twist not optimized and some rifles damaging the bullet a bit as it enters the rifling.

With the Labradar an up date to version 1.1.3 solved the 22 caliber issue.

I'm pretty sure one consideration was the need to produce a quarter million units. That's the figure I recall from the article in Handloader magazine.

In some forum I read where Litz is now using the new Oehler system 88. From what I could gather the 88 can measure time of flight to within a millisecond at ranges over 1000 yards, uses GPS, radio and acoustic targets and is battery powered. Given the quality of Oehler stuff and the skill of Litz I expect we'll see even more accurate data in his next book.

[bleep] A Aalf that is some very nice shooting brother and I don't compliment much.

It is indeed hard for me to wrap my small brain around how someone can't realize/understand/agree that a single grain of powder can, will and does make a difference in combustion energies produced.

If I was that anal or desired such beyond what I get on my gear you can bet your fart maker that I would have a scale that would do exactly such.

The only book you'll ever need!

Has anyone considered...........ah, who am I kidding.


Carry on.

Haha makes me wonder how I've a garage/shop full of bone.... Puzzys...

They key word in hunting, is "hunt"...... But that's simply not cool. A "hunter" needs to shoot rimfires and everything else at dumb range, cause there's nothing else to do.... Poor dumbphuques.... Don't "wonder" when a wife strays, or a sibling eats a boolit.... Hint, re hint, re hint +++ P

Oooooops the magical word, "hunt".....

Mebee the do nothing crowd should say, long range "shooting"?????

"There are lies, damned lies, and then Statistics!"

There are those that do, and those that dream....

And then there are the west coast libs that live happily amongst the top ten gayest population whilst spouting judgement from their child chit filled holes, voted democrat the last seven elections and can't hit a can past 200.. Carry on

I vote R am a deplorable azz and shoot the chit out of cans so hold your tongue 9. We ain't all bad.

. Ps 1000 yards

And your drinking one of my favorites, you pass!! But I do prefer bottles in that flavor if your ever buying.

Noted if the opportunity ever arises bottles it is.

Its the long range "hunting" forum, true. But its where we talk about precision LR shooting as well, like this thread.


Only one talking about hunting is you, for some reason.

I'd say if someone wants to be a long range hunter, he ought to do a lot of long range shooting first. Unless you're hunting beer cans like Fred. Fred, did you get an exit wound?

She was standing on the lid. Lol if it helps I shoot sticks, rocks, paint dots ect.

That's impressive penetration, must've been a Barnes.

I'm not seeing evidence of the "4 razor sharp petals cutting like a buzzsaw" thru that aluminum.

Coors - the .270 of beers . . . I drank a few when I was at Mines.

The 4 razor petals only show on PBR cans , thicker steel, I mean tin, I mean aluminum but anyway its thicker see.
