Went out and did some shooting this morning. Did a ladder test with 10 rounds of Varget in 1/2gr increments from 41-45gr and 10 rounds of R15 in 1/2gr increments from 40-44gr.

Did the test out at 400yds. The Varget seamed very consistant vertically more so then the R15. But looks like I might try to load up some Varget load #'s 5, 6, 7. And R15 #'s 25, 26, 27.

Had about 10mph wind gusting to 15

Then see what kind of groups I can come up with.

Re: Range Report Howa .308 Ladder Test w/ Varget/R15

It helps you pick a charge that has a sweet spot for your particular barrel where theres a couple rounds that are very close to each other. Big help for finding the perfect round for long range shooting.

As you see 5,6,7, and 25,26,27 charges are very close in vertical stringing. So I will prob load up 5 of each one of them for group testing.

Here's some info on it.

Yeah after each shot, had a friend with me running up too it on a 4 wheeler after each shot marking it.

what accuracy do you get out of your howa so far, and what coal do you use .
have a howa too and have a hard time getting under the 1 moa consistantly, but thats probably due to me beeing new to relading

Dont know yet trying to find a load as we speak, I am trying Varget and R15 powder so far.
 
Re: Range Report Howa .308 Ladder Test w/ Varget/R15

That grouping shows nothing..

Post up a real 10 shot group.

You obviously dont have a clue of the purpose of this test, I will have a nice 10 shot group once I settle on a the perfect load.
 
Re: Range Report Howa .308 Ladder Test w/ Varget/R15

I read the article the same as you and yes I do understand the purpose of the test I do it my self when working on a hand load. But it doesn't show a true 10 shot grouping.

Who ever said anything about true 10 shot group with 1 round, each round was with a different charge.

You may have read it, but clearly you have zero understanding.

On a properly executed ladder test, you should be able to plot the shots as they rise up the target.

I took the liberty of dropping your photo into autocad and tracing the progress from one shot to the next in a time-based manner.
The first shot is to the left and the last shot is to the right in each string.
In the graphic below, I show your varget shots, then your RL15 shots and then what an ideal ladder looks like.

When you look at this graphically, you can remove all the windage errors which are unimportant to the ladder test.

What you do NOT want to see in a ladder test is shots with higher charges falling below shots with lower charges.
This is an indication that your aim is not consistent and therefore the whole test is not to be trusted.
Your varget test is basically inconclusive.
Your RL15 test was executed much better, having only 1 shot that should be discarded from the data set.
 
Re: Range Report Howa .308 Ladder Test w/ Varget/R15

Thank you^

I get what hes doing. I understand very will because I do the same thing. I'm saying NOW show a 10 shot group on what that single powder weight does. So we can see consistency from the specific rifle.


I just don't think you are understanding what I'm saying......
 
Re: Range Report Howa .308 Ladder Test w/ Varget/R15

you is high tech my friend.

Re: Range Report Howa .308 Ladder Test w/ Varget/R15

I guess I'm with the rest of the group and completely confused..Perhaps somebody can explain because this just looks like a HOT MESS to me..A 400yd group shot in 10mph winds with 15mph gusts???

Somebody esplain???LOL

Thanks for ploting it out, but as far as the loads being up and down, Im new to shooting fairly long range but dosen't it have to do with what note of the barrel that particular load leaves the barrel at?

It does, but the barrel is not moving up and down enough to change the actual point of impact nearly as much as a difference in charge weight (velocity) does.
What you are looking at on the ladder is the DIFFERENTIAL in charge weights so that you can choose a load that will be most tolerant to scale variations while loading.
As you increase the charge, the bullet should still "climb" the ladder no matter where it came out of the muzzle in it's swing.
 
Re: Range Report Howa .308 Ladder Test w/ Varget/R15

Got a chance to get out a shoot some groups with a couple of different loads. Pretty happy with it's performance for a out of the box factory rifle. It was cloudy this evening and the chronograph wasent working very well.

5 Shot groups @ 100yds

Varget loads

Reloader 15 loads

Wish the chronograph wasent acting up so I could see the consistancy of each round, but I might try some more of #17
 
Re: Range Report Howa .308 Ladder Test w/ Varget/R15

Nice groups and good work. I like #27, with R15.
mind if I ask what your rifle settled on, looking to do the same. just waiting for the brown truck to show up at me door step.
Either way good looking groups.

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: ZeroDown</div><div class="ubbcode-body">anyone ever try setting a camera up near the target? Thinking of borrowing my wife's just for this! </div></div>

I saw a setup recently on the tube on- of all places- an airgunner show.

It was a wireless camera, and would transmit back to a portable monitor. But why? That's why we have spotting scopes, if we can't see the hits with the optic on the rifle.

If for some reason we need to "share" a target with a different load bullet, we just make a little sketch of the target as we're shooting and note which hits are what...updated after each shot.
