OCW load analysis help please

i bought a second hand savage 12 FLVSS in 223 rem.
i received my reloading stuff this week and prepared 21 cartridge from 23.5 to 25.3 gr. in .3 increment. they were shot in a round robin fashion as asked by the method. the result are oustanding for me. i never had such good result, especially on the first try. but it's my first varmint rifle also. so since i got a 21 shot 1.06" group. ( 19 shots in 0.680'' if i take the two outsidemost out of the group) if i lay the 7 targets on top of each other, i don't really know what to use for ocw.
since h335 is apparently temp sensitive i tought 24.1 gr. would be good.
the temp today was about in the middle range of what i would encounter in the field (60-80 deg for rockchuck in summer- 10-20 deg for coyote in winter
25 gr also seem good ,and would give more velocity. but a more consistent load is more important to me.
so i would like your inputs on this from you pros out here

temp: 45 deg. no wind
bullet: 55 ballistic tip
powder: H335
col. 2.300
brass: new win.
primer: fed 205

note: 25.3 gr. has 2 shots in the left side hole

I would say 25 and 25.3 are your best, they have the least amount of verticle, and their POI are very similar.

My guess on W3P .308 230 Grain Bullet: G1 .740-.755

I would go with 25gr, next step would be about 5 different primers, then I would do the distances off my lands. I predict a tac driver when your done.
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.

Re: OCW load analysis help please

thank you guys.
i will load 25 gr. and try different COL.
since 2.300" is my max mag lenght, i will try 5 shot groups of
2.300-2.990"-2.980"-2.970"-2.960" and 2.950"
sounds good?

I think instead of just going with 25gr, I would load up to 25.6gr(if pressure allows) and see if my grouping and velocity was pretty much the same. If so, I would go with 25.3gr and try seating depth changes with that. This would provide a load that is not too sensitive to changes such as temperature or if your scale happens to be a little off one day to the next. This would give you .3gr either way to deal with. This way anything from 25-25.6gr would prove to shoot well over all seasons and conditions.

I'm pretty sure once you go to changing primers or seating everything is gonna change.

Re: OCW load analysis help please

thank's everyone for the help
last week i tested this load a bit further.
here is the three 5 shot groups i got using 25 gr and a coal of 2.300 as in the ocw test.

the first pic that have 2 holes on the left and 3 on the right was the last group i shot. a young gentlemen shooting next to me noticed that i was not consistent in my grip. and told me that some shot i was wrapping my thumb around the grip, other times i was putting my thumb on the back of the grip.
so for the last 5 shot, i tried 3 shot one way and 2 the other. i guess he was right.
it's nice to have someone watching. it helps pick up things i was completely unaware i was doing.
it's pretty new that i go to a range. i was shooting alone on my uncle's land before.
but i really like meeting experienced shooters

i tried also at 2.290'' and groups enlarged in the .75" range
at 2.280 it went in the .80-.90''

i also tried just a 5 shot group at 2.260 that went 1.1".

so i guess until i can put my hand on other brand of primers i will shoot some more and try to improve the driver it may help more than messing with the load
but i will sure try melloyello's advice and try 25.6 to see if 25.3 might be better.
