This is the first video out of six or so that finally made sense of this technique. And, it was done in short order. Much appreciation and thanks from Texas!
Simple, to the point, very very clear and no BS. Fantastic explanation and am glad I found this after wading through a lot of pretentious videos. Keep up the great work.
Read Dan Newbury's site (3 times) and had an understanding of ocw, then came here and watched your vid and now I feel far more confident in trying this method. I ladder tested my .308 and "thought" I had a half moa load but could never repeat it - I now have an idea why I could never repeat it! Excellent video - well done! Subscribed...
Excellent explanation. Also see people load close to or at max to get higher velocity thinking it will help them at longer distances, when often they lose accuracy.
Just started watching your videos and have now subscribed. I understand the ladder test for point of impact barrel node however your powder temperature shift explanation will be considered during my next load workup. Thanks for the video!
have you tested these at over 26 grains? Looks like it may be pulling back into a stable poi at 26 grains. You may have an OCW at 25g and then another somewhere just above 26g?
hmm ....I guess I better pay closer att. to horz. poi shift . ive noticed obvious elev. changes but never clued in to this one . thanks for the schooling :)
Hi Richard. Great video well explained. I have been loading 223 for about a year now, getting good results i.e. hit the 6" target at 200 yards using 53 grain Sierra match kings.What i want to do now is get more accurate. Is the best range to test 223 100yds ? Are HPBT bullets better than HP (both Sierra matching) ? I use H322 powder. Should i start experimenting using the OCW load testing as you describe. Any advice will be well received.
I don't know about those bullets Johnny. I use 80gr amax in 223 but don't know those others well. I do think that tuning things with OCW is crucial and i also like testing much further out. What is hard to tell apart at 100 is clear as day at 300y, for example.
+Maureen Halkett Hi there :) It's irrelevant and zero is not an issue. It's poi stability (wherever that may be) plus minus of your powder charge that you are looking to establish
Look! I have watched many videos. If you choose to waste that many rounds? Ok. Shoot a 10 round group from min to max charge. At some point on the “ladder”” a few bullets will group. Now ? Concentrate on primer and bullet searing depth. All rifles barrels will show you harmonic distortion in that ten rounds. Another ten rounds shows the depth your particular rifle shoots. Then a few rounds to test primers. It’s not rocket science. Discard a cold barrel shot, but record it. That’s where your first round will hit if hunting. Come to my place and prove me wrong. I don’t wish to be you tube patreon. Others do

+COMB0RICO Thanks man. Merry Xmas :)
Bravo! Excellent job. I'm Dan Newberry, BTW... and you definitely did a great test and interpretation.
Simple, to the point, very very clear and no BS. Fantastic explanation and am glad I found this after wading through a lot of pretentious videos. Keep up the great work.
never , ever thought like this. I went for the best group always. Thanks Rich again for another step closer to being consistent over 400 !
We were the same mate but this really helps control things in variable temperatures. Cheers
cheers pal - as they say "you never stop learning" thanks for taking the time to answer - G

Excellent video ! Al in the clear for me now. Some of the other explanations are eventually contradicting themselves.
Keep up the good work

Easy to understand. Thank you. heading to the range now!

thanks for making this more simpler to understand

Would have been interesting to know what powder you were using.
great video ! Where or how did you start with your initial zero, before you started your OCW test ?
What about velocity? Do you consider small ES spread as well? When your doing this test
Daren, this is a friend's factory R700 in 223
I think it was 100y. This is the first step in the load development
Maybe its a stupid question but on what G do you Zero you rifle before starting the OCW testing, is it the lowest g of your loads?
i was wondering this also.. like 2 clicks right and that blows this theory right out the window
hmm ....I guess I better pay closer att. to horz. poi shift . ive noticed obvious elev. changes but never clued in to this one . thanks for the schooling :)
Clever stuff!
Shooting after the obvious zero session, is that correct Richard,
What was your caliber used in this test and at what range?
Quick and to the point. Me like
What seating depth was this test done at??
thx

When you shoot did you fire all 4 shots for each load or did you fire one shot for each load 1-6 then back again 6-1 and repeat and until finished?
+dunbar1471 Each load at a time buddy
I thought with ocw test it was a round robin style 1 shot of each load then you repeat until finished.
dunbar1471 Some folks ladder test like that, yes.
How do you know that the two groups that are a minute left are not the true zero, and its the others are shooting a minute right.
+Maureen Halkett Hi there :) It's irrelevant and zero is not an issue. It's poi stability (wherever that may be) plus minus of your powder charge that you are looking to establish
So, now that you know your OCW. You simply fine tune with seating depth?
yes
well said. subscribed!
I still don't get it
