i shoot a cooper .223 with 1-14 twist. i was under the impresion that H335 was to best powder for bench shooting my gun, but after reading a few posts it would seem as though h335 isnt the best and powder choice can effect my groupings a lot more that i thought. so im wondering what would be a good powder. or do i just have to try them all?
 
well what kind of groups are you getting at 600 yds ??? i have used 2230 and 2200 at 100/200 as well as n133 and 8208, and of course 4198.
 
223

lf you are tring to go long with a 223,l would try Sierra 55gr
Blitzkings with Varget.BUT on paper past 450 l don't know.
Best on varmints to about 350...

There is a number of great powders that make the .223 an accurate rifle. I found that with 50 grain pills VV N133 and Benchmark works well, however 60 grain pills I'll use 4895. You might have to try a few different powders to see what your rifle likes. :D

Maybe you could try buying a book??

i own about half a dozen reloading books. one for .223 in specific. and if you can tell me where in any of them i says what powder works best in a copper .223 out to 600 please let me know the page.

my issue right now is im virtually clueless on how to get my loads right. there so many factors that im not sure which is best to work on first. im guessing that i should get my powder load right. then get my seat depth where it needs to be. and then play around with the powders.

but even i do it by the book. i can only make it to the range a couple times a week at best, and i may just have the load i need that day but the winds high or the humidity is off so it wont group good, and i wont know if i have the right combo or not.

its starting to frustrate me. i feel like a half blind man in a dark room. so i ask alot of dumb questions on here hoping you guys will guide me.

i apologize if you know alot more that me, but if you all you have to say is snide comments please keep to yourself
 
so is determining what powder works best the last thing i need to do as far as load development?

I have always chose a powder slightly on the slow side for any caliber. I am always looking for case capacity to almost be full without getting into dangerous pressures. Why, dunno, just works for me.

For the 223 I have shot W748, AA2460, H335, VV133. All powders seem to shoot well for my rifle.

AA 2460 with 40 grain bullets have worked well for my Ruger. Find your OAL to just touching the lands and work from there. I have found that just touching the lands is a good starting point.

What are your intended goals for this rifle? What bullets do you plan on shooting? Brass and primers as well?

I think guys can answer better if we know what you have and what you plan on and what are your goals.

Just keep asking questions!

Cooper 223

all Cooper rifles come with a recomended load. Start with the factory load and work from there.If it happens to be H-335 or which ever powder do a ladder test in small increments starting -1 gr. and work up. If you bought the Cooper used and don't know the factory accuracy load e-mail Cooper they will tell you.

right now im just using brass left over from the black hills ammo i bought a few months back. im going to get 250 lapua brass empties though.

i ordered a carton of 52 grain LD bullets from JLK/Swampworks because they had the highest BC i could find in a 52 grainer.

for primers in just using CCI. 400 small rifle i believe they are

and agian im using H335 for powder at the moment. but i obiously got a little excited and started hot at almost 27 grains, but now i see the error of my ways and intend to seat to the lands and start at 24 grains and wok my way up.

as far as consistend FPS. is this something that certain powders will maintain much better than others or is there more factors involved than just the burn rate?

also if i seat to the lands from what im seeing unless im doing something very wrong which i dont think i am i get a COL of 2.335! with berger 52 grainers. ill double check it tonight incase i was mistaken and it was 2.235, but i think its 2.335. although i cant see why a company like cooper would cut the throats that deep.

the test target says they used H335 and a 50 grain blitzking, but i called cooper and they wouldnt tell me the charge they used. also in just messing around with the blitzkings and a couple other V-max types. it looks like mine shoots 40 grainers better. course those where fairly hot loads. (apx 28 grains of benchmark or H335)
 
Test Target

Included with each Cooper has Powder(type-weight)Bullet (type -weight)Primer, AOL,and Velocity. Use those components and test (indvidually) at a time. I don't know which BH ammo you're useing but Blue Box Hills ammo from Cabela's won't cut it in the accuracy dept.
 
ok, i dont think a 1/14 twist is gonna make it at 600. 55 gr is about max, tho you could try 60 and see what happens. 600 is normally shot with 75/77/80/90 gr bullets with twists from 8 to 6.5.

Roger, sorry but i must disagree with part of that. the test target doesnt say anything about AOL or velocity and i asked cooper about the charge and AOL/seat depth but they would not tell me. but yes knowing AOL, charge, and velocity would save me ALOT of time

also i was using the new red box ammo not the blue. not that it makes much difference. still crappy brass. working on getting some lapua

yeah unfortunately, your very right. but i figure if i can do a 1.250 5 shot at 400 with out using a well developed load. ill at least be able to keep it under 2 inches consistently at 500....hopefully

edit/PS
thanks for confirming that for me also. i had a coworker tell me i was full of it when i said some AR's have 1-6 twist rates and can shoot long 90 grainers
