Home Forums Hunting & Shooting Long Range Hunting The reason why the Audette is the greatest, never-improved upon Load Development Method

Leave the chronograph at home

Impacts on paper at long range matter

the reason it works is because field conditions always change. lots of powder change. for instance I have a load with varget for a 22-250 that has the same POI at 100 yards in a 4 grain window. another instance. I burned up all the n133 for my 17 fireball. I started a new lot that is brand new. load sped up by 100+ fps. same POI. if a load is that finaky you don't want it. I load up 7 or 8 cases with different powder charges up to what I am pretty sure is slightly beyond max. The load that is most forgiving up to and past max is the one that normally gets picked.

Cool vid RC. Thanks.

I thought so as well. I’ve never used a chronograph for the sole purpose of load development by examining SD or ES.

How many shots per charge level are you shooting in your ladder?

When shooting the Audette, only one shot per increment is used

That conjures the demon of statistical (in)significance.

Good video. Didn't need this guy telling me this though. I always say the real proof is on the target. I've seen so many guys struggle at the range, wondering why the loads they are working with that have the best numbers, don't always show the best precision on target. Now throw in concentricity and other factors. That seems to have more of an impact on precision than chasing your tail with SD and ES.

I thought it was good as well, with so many I see doing load development by simply shooting ladders at 100 yards and paying attention only to chronograph readings to choose their load

It really doesn’t rely on statistics.

It’s ALL about isolating a barrel exit time during the muzzle’s movement that nullifies vertical stringing at long range.

The very definition of a good long range load.

Does this mean you are Audistic?

Yeah. The small sample size problem applies to POI as well as velocity.

What may look at first glance like "nullifying vertical stringing" may actually just be random chance. Repeat the same ladder test multiple times with the same results, and there starts to be some correlation.

Shooting the loads in the visibly obvious node and picking the best confirms the nullification of vertical

It also results in good long range load identification in as little as 10 rounds

Seldom have I had to repeat an Audette.

rcamUGLYa,


Your ladder is worthless.


Signed, the bell curve.

Excellent input, as normal

😂😂😂

Very interesting video. My concern with "my own" accuracy and loads has always been "do I have a large enough sample size to make any determination?". After reviewing this video, it reminds of how I often wonder how many times I have actually discarded what would have been, or was, the optimal load from those I created and tested.

Bench shooters chase the rabbit hole.. every time you improve one thing, you have to go to the next variable to make it better…

Velocity mostly comes from pressure…. And leaving the barrel at the same time comes from another type of consistency, and how many, and much vibrations are in the system you are shooting.

Small samples have always had the issues he’s talking about - however, that’s only one of the variables.

With my PRS rifle I can’t find a group that doesn’t cloverleaf at 100 yards these days so I had to move out further, and shoot at sun up to refine my loads more.

Pencil neck talking nonsense
