Hi Guys !
Just wondering what the majority of u use (LADDER or OCW) ? And why ?
Depends on what I plan on doing with the rifle.
I like the ladder for mid to long range shooting and OCW for hunting.
Im strictly bench shooting ! So do u think Ladder would be better ? 500 yards max.
I have done both and the results or final load were dang near the same results. With the ladder test you need to
shoot at least 300 yards or so to really get an idea of your results. With the OCW test you can shoot at 100 yards
and find what works. Some places do not have ranges more than a couple hundred yards so the OCW test would
work at the shorter ranges...just my experience!
I've done the same comparison with essentially the same results so I don't stress about which test to use. Much prefer a ladder though because it requires fewer rounds. OCW I've found to be more versatile because it can be done with anything whereas it can be hard, at least for me, to make sense out of ladders with less accurate rifles.
I too have used both and both have delivered great results. There are those who have been lead to believe a load for long range can't be tuned at short range. I think either method requires the shooter to have an open mind and the know-how to interpret the results objectively.
I use a ladder test, on a calm morning before mirage kicks up, in .1 grain increments, at 400Y, concentrating on the high node. If one does his job and the rifle is capable, it'll be obvious where the node is.
Last one a few months ago gave .2" vertical for 3 consecutive shots - done.
Which do you prefer?
I would be interested in your method of load development
What is OCW?
Optimal Charge Weight test.
I went to the website the instructions were on but, while the URL still appears active, the page is blank.
I haven’t done either , that’s why I was asking . I wanted the most accurate way..
Well than where do you get your ammunition
I load it myself . Just started with the Sierra accuracy load because I needed to start somewhere . It seems to shoot pretty good , but just wanted to see if there was more accuracy to get !
So , 30.0 gr Varget and a 107 Sierra is fine just may not be the exact tune for your rifle as far as seating depth and final tweaks
I’ve got 5 each loaded 29.0-30.0 in .2 increments . Hopefully will be able to try this weekend . The Sierra OAL 2.375 put me into the lands , which I thought was odd , but 28.1 load shoots pretty good that way . Don’t mind going higher if I get good accuracy still and it’s not too hard on brass or barrel life . Do u think I should try the 28.1 to 29 also, or just 29-30 ? Thx for your help !
Got an answer back from Dan. He moved the info to a new site:
Too many times I see guys talk about their OCW results and too many times, when questioned, they have not followed instructions. Dan went thru a lot of work to get this down in the correct order and it has to be followed to the letter to provide meaningful results.
I would shoot 29.0-30.2
Find a flat spot then load in between for the following seating test
I use the “Cortina Method”
I do OCW for my OCD
I dont even bother putting rounds on paper anymore for load workup. I have a steel plate at 400 yards and a magnetospeed to record velocity. Hits on steel are noted and i go with the tightest ES/SD velocity i find . I usually find a couple nodes that shoot good at max load and one below that. I dont shoot any competition,just long range steel plinker.
