Consistent/repeatable Harmonics?

Ladders also help with accuracy from a powder measure as you have a couple tenths leeway on your throw. Not an issue with smaller calibers but when your throwing 70 plus grains of powder even in a BR3 it is often off a tenth or so.

Without wind flags it's a wild ass guess disguised as a process

Tell me why wind flags are necessary to find consecutive rounds that impact on the same horizontal plane?

If you need to be told something so simple, you probably shouldn't be offering advice on accuracy

'lia,

I'm in the unique position,that dumb [bleep] line up for miles...just to tell me their stupid [bleep] schit. All of which I appreciate,for it's unrivaled humor.

I REALLY enjoy this stupid schit and all the hilarity.

Thanks!










SLM,

Please don't go slightin' the inherent humor of Goat [bleep].

This schit is [bleep] funny!











Ken,

Vertical is nipped by uniform velocity.

Though I do LOVE this .1gr of this and .1gr of that,[bleep] STUPIDITY.

Next it'll be a Global Warming Ladder.

Laffin'!










'man,

Harmonics is easily skewed in a multitude of ways,but inconsistency velocities...do not get consistent downrange,after having climbed a [bleep] ladder.

No matter how badly a dreamer,wishes it to be.(grin)

Hint.










spj,

Jeezus [bleep]...that schit was funny too.

WOW +P+!











'nan,

You might just be onto sumptin'...regarding atmospherics.

There's hope.(grin)

My comment was in the other direction, namely, consistent velocities per se don't assure small vertical dispersion.

Yep.

Load #3 had the most consistant velocities for these shots. Only differed by 6ft/sec. Yet the group size is almost double load #2





"LONG RANGE TUNE.... Here is an interesting set of trajectory plots. No matter how carefully one loads his ammo, there are going to be small differences in muzzle velocity. Consider a load with an average muzzle velocity of 2915 fps with a muzzle velocity variation of 15 fps. Then consider this load tuned for zero vertical at 100 yards that overcomes that small difference in muzzle velocity.
This same load will be out of tune by 73.23-71.50=1.73 inches of vertical at 600 yards. However if the load is tuned so that there is 12.21-11.92=0.29 inches of vertical at 100 yards (with the slower muzzle velocity hitting higher) then there would be zero vertical at 600 yards. This chart is for a 6.5mm 140 gr VLD bullet with a 0.64 BC. A similar chart or table can be made for each long range load. If you are in tune for zero vertical at 100 yards, you will not be in tune for zero vertical at 600 or 1000 yards."

"Higher velocity shots exit early while pointing lower at the target but drop less in reaching the target.
Lower velocity shots exit later while pointing higher at the target but drop more in reaching the target.
Counteracting combination. Good.


Higher velocity shots exit early while pointing higher at the target and drop less in reaching the target.
Lower velocity shots exit later while pointing lower at the target and drop more in reaching the target.
Bad additive combination. Bad. This is currently being called "Negative Compensation".


Isolating the above is the purpose of an Audette Ladder

It rules.

You stupid mofo.

I second that!

And if you don't know if the bullets are dispersing vertically due to barrel harmonics or atmospheric changes, it's still a wild azzed guess, where I'd guess the process would include : shoot, make a guess, vary load by .5 grains. With flags you have more information with which to identify the cause, something much more quantifiable than a theoretic node.

Ah, rca and tak, all we need now is swampy for a truly memorable triumverate of stupidity. Say something about Remington; should set off his web-crawler

Sounds like you have no understanding of anything involved.

With your learning curve we'd be lucky to show you how to measure group size before the next election. Tip: if our two outer bullet holes aren't touching, the group size can't meaure smaller than your bullet's diameter.

Do you use 100 yard development for your rifles

About a month ago, there was a post on how to work up a load for a rifle, I think that this is a good place to repeat that post.

200 yds is where the short br game is won or lost, and if you're shooting out to 300 that's where you should hone it in. At any distance, you have to use flags to weigh the effects of any changes you're witnessing in the poi. You can have a gun that will shoot zeros, and if you don't monitor the changes in wind direction, speed, mirage, and all the things that can happen between you and the target, you'll never know why your groups work out as they do. That's the problem I have with leaving that out of the shooting, or the load development process. It's 50% of the battle.

I see.

I also see you have no idea of what constitutes a fine long range load. 200 and 300 yards aren't long range. A little vertical at those ranges won't kill you.

When you're shooting 600 to 1200 yards and you have a load with a minute or more of vertical you have more than just wind to worry about. You have to worry about where your barrel will haphazardly throw the shot vertically AND where your piss poor wind reading skills will place the bullet horizontally

With loads that consistently print with minimal vertical dispersion at every range and solid drop data, the wind is the only issue. That's tough enough.

100 yard development works well too, but sometimes will fool you. You discovered that at long range.
