H20 case fill Quickload question

[Joe R]

Your correct I don't have one .
I would guess I have over 10 up dates .
If you were at the shot show you would of seen our product in his booth.
Sometimes it don't pay to be sure. Larry

My apologies to you Larry,
with ten updates you're obviously one that knows way more than I do. I've only been using it for a couple of years.

Just curious what is your product? And whose booth are you referring to?

I agree with the concerns over your bullet/seating entry, and of your chronograph accuracy.
What chrono/setup?
Do you really have only .163" of bullet bearing seated?

Have used it 13 years it hasn't failed me yet. So I will Larry

But have you failed it?

It is a powerful software, that can give wrong answers, as good as it can answer them, dependent on the user inputs and property selections and settings. And it can be manipulated to output about any answer one wants, right and wrong.

RAS tuners or accuracy shooting system .
8 year ago we started . The last 4 years we have done extensive testing of all tuners while
Perfecting our own.
As it stands now I use QL to find my load Then I tune the barrel to the load. Yes it is different but it works
Saturday I took a new gun with a new shooter
Made him shoot and adjust the tuner 10 shots 3 adjustments they we're touching at 200 yards The next two was one raged hole he move to 600 after getting it on he hit 10 in a row . The target is 5" gong. I haven't checked the Es I can lower that with primers and seating depth .
Like I said my way of loading is different.
But it works for me
Rim fire shooting has done it for years .

Heres how I do it and it seems to work.
I do 5 fired cases with water to where any more overflows. My rationale is the fired case is the size of that particular case (and the chamber)fired in my rifle. I average the 5 readings and enter that.
I check the temperature setting (someone else mentioned this) and the weighting factor.
Then I load 5-10 upper midrange loads with the components I plan on using and chrono them. I generally throw out an extreme high or extreme low if they happen to occur and then average the rest.
On the box in the upper right on your screen I go to the bottom of that box and enter the load I just chrono'd, hit the button and see what it shows.
There will be a descrepancy between the load and what QL computes.
Then I press the button at the top left of that same box just to the left of the powder pull down. That allows you to adjust the burn rate (Ba) without permanently changing it. I adjust it until the speed matches what I actually chrono'd.
Load a few more and chrono them. They should now be very close to what QL projects and give you something you can work from.
Hope that helps.
By the way, that is very little bullet in the neck you seem to be using. If that is correct then I would be checking my neck tension on that as that could make a variance in your readings also.

That's the address for QuickLoad videos.
May help clear things up for you.

Interesting point of view

Larry,
I know that tuners work, I tested out an Eric Cortina tuner (see picture). Unfortunately in F-TR we have a 18.18 pound limit including the bipod and I don't have 3 oz to spare for a tuner. I might use it on my Open rifle.

Regards,
Joe

Normal everyone does the same .
Looks like you missed the vertical up tune the vertical download shows promise . Larry

Why would you use a un size fired brass to set your case capacity . You have added. 6.4 more grain to the default setting . That is over 10 percent difference . When you do H 20 capacity size the case and trim to length
Install a sent primer in bottom side up. Put the case on the scale and zero the weight. Carefull fill the case Wipe off the bubble and dry any excess off then weight. That is a references of one case . Do the same to at least 2 others. That will give you case capacity . To enter . I see you only have
Only .135 Shank of the bullet in the case is that a mistake? My advice is go back to the default setting and start over . Larry

Would you care to explain to me how much the volume differs in H20 volume between a full sized case and a neck sized case that I wanted to use. The neck sizing die will only squeeze the neck to my preferred size while the rest of the case is still the same dimension as a fired case. A full sized case will have way less H20 volume than a neck sized case. Then the H20 volume will still be very close to 88 grains of H20 with a neck sized case compared to a case H20 volume that has been full sized. I am curious.

I have no idea how your chamber is and how much your dies is sizing. You got both with you answers in your hand . Check them . Let us know. Larry

I think I may have a understanding what you are trying to explain. I have the sheet with the OBT vs Barrel Length with 7 nodes on them, example if my QL velocity currently says 3175 and my chrono velocity is 3280, then I change the Ba number , let's say 0.5187 to 0.5390 until my QL velocity is 3280 , the same as my chrono speed, then I look at the Barrel Time 10% PMax to muzzle on QL, and let's say it is 1.3442 on QL and my Excel sheet says on node #6 is 1.883, then I increase my powder charge weight on QL to increase the OBT from 1.3442 until it gets to 1.883 ish?? I hope this is how its done, let me know. Thanks for your help.

I don't use BT but the rest you did is correct . The next Lott of powder or temperature change you will do it again . Larry

Either your spreadsheet is wrong or you dropped a digit. Node 6 should say 1.3883. You're on the right path.

Yes Joe, you are correct on your number, I did miss a digit, lol. I have that exact number 1.3883 on node #6 for 25.5 inch barrel. Thanks a ton folks.

Thanks, do you do the round robin or ladder test when trying to find a load out of a rifle?

 

[dewey7271]

I may have read your post wrong but on the Ba adjustment you are correct. On the other part remember as you increase powder barrel time goes down. I'm sure you know that just wanted to be certain.

Sure the bullet speed up . Larry
