Hey guys !

First ladder ever ! Please give me your opinions on where my node might be . 300 yards , 6br , 105 berger Hybrid , Varget .

Much appreciated !

3, 4, 5, 6, had the least vertical dispersion. I'm shooting similar loads of 6BR with Nosler 105's. You can work on seating depth at this point. Pick the middle of the node and just throw/meter loads. You probably can throw loads to within +/- .1 grain and will be close enough.

That’s exactly what I did . I loaded 5 each of 3,4,5,6 .

Thats exactly what I did ! Loaded 5 each of 3,4,5,6 . Load #4 (28.7g) shot a half inch group at 300 yards . So I loaded up 50 for my first F Class match this Saturday . Wish me luck !

Thx

Ladders can be terribly deceptive and frequently don't give anything useful. I don't use them.

Look into the OCW technique. The problem with ladders is that most rifles/shooters that are shooting OK will shoot about ½ MOA vertical. You don't know if each shot is high or low in that 1.5" (at 300 yards) dispersion or if you pulled one. Shoot groups and you can see better.

You make a good point !

I did shoot 5 round groups of 3,4,5and 6 . Load 4 (28.7) grouped at .5 inch . The other 3 groups were 1-2”. But again , was the .5 group a fluke ? Because .1 grain over and below opened up . Not sure I’m a good enough shooter to put them all consistent !

I disagree.


Ladders are pretty standard. The key is to shoot more than one. OCW can be deceptive too. Once you find a node, then do as directed and do depth testing.

I’m not a fan of using a ladder test w .1 grain increments. I usually load 3 rounds of each weight in .5 grain increments and shoot groups at 300 yards. Take the best group than either tweak it .1-.2 increment or play w seating depth. Once it shooting up to my standards than test at 1k!
 
I don’t really care where they hit, I look for a velocity node then look to group. At distance it’s velocity ES you need to be worried about. Just my 2 cents.

Unfortunately no Chronograph !
 
Ah, yeah I’d recommend a chronograph you really are looking for a node that will give you a fudge factor in charge weights. So that when you load it accepts a .02 to .2 tenths of a grain for the same velocity.

.02 ????? Can only measure to the tenth .
 
.02 ????? Can only measure to the tenth .
??? yeah, some folks can spend some cash. If a .4 grain window producing the same velocity your golden. Throw to the center of the node and if you’re high a tenth or low a tenth. Who cares? Read “The Perverse Nature of Standard Deviation” by Denton Bromwell.
