Whats the best way to distinguish shots in a ladder test?

The lighter Colors don't seem to show up as well as the darker colors so if you can't borrow a higher magnification scope or spotting scope video your hits.
Take notes so you know which shot is which and you are all set.

Do it out in the desert with a buddy downrange who can walk over to the target and mark each shot with your charge weight.
Use radios to communicate when the range is safe and when it's hot.
10-20 ft of space between the shooter and the bullet path is quite safe.
When you are in pits, the bullets are often just 3ft above your head.

Your downrange spotter can also give you wind calls which will dramatically narrow up your ladder, making it easier to read.
600yds will give a much easier to read ladder than 300.

I also considered separate targets on the same large white board, but i think it would be difficult to correlate the separate targets into one meaningful group to analyze it.

Could you overlay the targets after you've shot them to get your desired info?

rubbing alcohol on a Q-tip will bring the lighter colors out.

sharpies on bullets have been known to change the POI relative to a naked bullet.

do it on a range with a puller or do it with a shot camera to mark the shots

The OCW shows harmonics changes - the 300 yard ladder does the same plus the SD ES runs in to further influence POI.

I get that they both have a place, but had faster and better results using the OWC “round robin” over something like an optical or Labradar chronograph- These are acting secondary to confirm the the velocity in the groups that have the similar POI have similar SDs and Velocity. As such, the chrono- is working in conjunction with the OWC to act a bit like the ladder, without the wind etc. I think the super thick benchrest barrels and benchrests tend to shoot much more precisely so the longer range development might work much better.

FWIW; I have seen several guys shooting ladders that have so much shooter influence in the mix it makes little sense.

Back to the colored projectiles for 300 yard ladders. I’ve never had enough colors. I have only had black, blue, red and green. These all print fine but not enough to cover all the charge weights. So I’ve just posted up 4 white printer paper sheets with a black spot in the middle separately on the same backer. Then pull and look and compare-

Not saying this anything more than what I have been doing.

I did the marker trick and it worked out pretty well. I had only enough colors to do half of my rounds, so I shot the first half, went and marked them, then shot my second half.

The other way I would do it on a public range is to use a large shoot n see target. With your rifle scope you can easily see those holes at 300 yards. Just mark down the approximate impact on a note pad at the the bench after each shot. If you want/need a really large shoot n see you can make one from poster board, packing tape, and spray paint. Get a bright color poster board, and cover it with a single layer of packing tape. Spray the taped up board with black spray paint. Stick a single dot on there and you have a nice large target.

this right here^^^!!

if your not an experienced shooter and shooting off a concrete bench or a real nice front rest and bags then the chances of getting good data from a ladder test is pretty slim.

OCWs or this http://www.texasprc.club/preidloaddev is the fastest easiest ways ive found loads.

I am shooting off a concrete bench, with a bipod and rear bag.

I have position shooting experience that goes way back, but i havent shot precision for a while.

No worrries about a group at 300.

[LynnJr]

If you can, eliminate the bipod and use a bag up front. It doesn't need to be fancy just something that will hold the rifle very steady. A leg off an old pair of pants filled partially with beans and sewn closed on both ends works very well.
You want to take as much of the shooter out of the equation as humanly possible.

2 phones and use Facetime to see the target live /real time.

gotcha.

id been very interested to hear how your ladder test results turn out...and not so much the ladder test itself but if you actually find a load from the test.

[Dark Hunt]

The easiest way is to set up the same number of identical targets on a board at the distance at which you want to test. At 300 yards place three or four targets in three or four rows. Shoot one bullet at each target, left to right, top to bottom, using the same hold.

After you shoot, take down the all the targets, line up the edges carefully and trace the bullet hole on each target on to target one, (and number them).

When you're finished you will have target one with its bullet hole and outline of every other bullet hole from the other targets.

You can patch the bullet holes in targets 2-12 and re-use them with a new target 1 for your next test.

Why do people want a front bag vs a bipod?
