Home Forums Hunting & Shooting Long Range Hunting Ladder test, How, why?

Now I feel pressured. I just don't know if I'm ready to go that far...



Travis

I'm seeing a lot of your favorite stuff all rolled together here.

- HTG
- 308
- chrome moly
- 50mm
- 4.5-14
- paint finish


This must be one you really love to hate....grin

You could name it 'Train Wreck' or (abortion) 'Clinic'......grin.

I would say so.






Yes it is common to find a range of charges that put the bullet at the same POI. That's the entire reason the method was developed by Creighton Audette.

The final load chosen rarely groups like the test loads that are at different charge weights. Sometimes the node in the test is tight like the one we are talking about, and sometimes it takes some experience to read the ones that are not as obvious. I look for a string of consecutive shots that land on the same horizontal plane









With MY lot of powder, MY particular barrel, MY lot of 208 A-Max, and MY brass.


That is what an Audette IS! Most guys here are shooting a "ladder" for development and don't even know it. They're shooting it in some form or another. Groups, OCW round robin, etc. at close range. The Audette is just another form of development that simplifies the others and is shot at long range where it's easy to read the results.

You saw the guy's 308 Audette shot at 300 yards. Really tight. He has a good barrel that will shoot everything. To really hone in on the best load he needs to shoot the test at 600 yards so that the wheat can be separated from the chaff.


Powder lots vary in burn rate. You need to shoot the development every time a new lot is had. Every rifle may be different as to throat dimensions, barrel land and groove dimensions etc. My last lot of H-4350 showed pressure in the Creedmoor at 42 grains with the same bullet. The lot I have now didn't until 45 grains. This is why you can't just say, "the load for such and such is widely known to be 42 grains", load it and think it should work. It may or may not

Feeling pressured?

I guess you just need a kiss then rock on.





P.S.

Check with box and see if he can help.

Between Flave's sheep and his boyfriends, he's got lots to kiss.

Comedy is just not your forte.

My bullet isn't big enough to get deep into the hole.



Travis

Between TAK's rifles and quantities of spent primers he has lots of googling to accomplish.



Travis

Same could be said for reality.



Travis

I'll remember that qoute at the Icebreaker this spring, as I pull my Surgeon .308 out of the case and stroll down the line to where you're shooting......grin!

I knew when I typed that either you or Shane would be along... grin.



Travis

We'll both show up together.......grin! All in fun!

What are you bringing over this spring? Anything new?

Funny that you query this...today.

As I was curious what a 6.5" chop would do too.(grin)



Off to shoot zero again,clock the same lot and see WTF in general.

New tube on my 7-08 and I'm more happier with it.

I do have a .243 I'd love to have done and ready by then but not sure if that will happen.

Patton will have his 8T .223 AI.


Travis

Caliber and weight don't matter. It's all about construction.

.264 Win?

I spoke w/ him the other morning and he said that 22" was easier for him to work with. So thats what I went with and like you I'm feelin' like a kid at Christmas can't get here fast enough.

They're going quick 'flave....

Mark told me the same. 22" allowed him room to work... for concentricty. Bore to crown? He said it was easier to set-up at 22" versus 19".

The batch is 15 rifles, and 7 were reserved. I'm guessing mine is #8.

Didn't want to spend the money right now, but it'll be a little awhile before they are ready. Plenty of time to collect cans, or sell plasma . Don't want to miss a chance at an Annie repeater like this .

Jason

He told me the same thing about the barrel length.

I also didn't want to spend money right now but I wasn't about to pass up on this deal.

I've already got things in the classifieds.lol.

I probably need to give him another call to make sure my name is on one, he said to send him an email when we were talking on the phone but I haven't heard back from him.

Logic/physics ain't yours.
