I've got a couple of different brands of brass to choose from to shoot of of my prescision rig. just wondering what everyones thoughts are on the brass i have on hand. It's all once fired, the winchester being mostly the cheap bulk pack in the white box.

Winchester

I've had great success shooting my .223 M70 Coyote 9" twist barrel to 800meters at Connaught ranges during the crazy winds using 75 gr AMAX bullets out of Winchester brass! Great prices, too since my buddies shot their carbine matches with Wincheste White Box ammo and then left the brass for me.... :D
 
Ok. so Winchester it is.
what's the best way to sort it? i noticed with the winchester the neck wall is not the same thickness. should i trim all the brass to the shortest length? (I kept everything that was 1.757"+ and put the rest aside)
then should i cull the brass with the thin necks and then sort by volume? what's the best way to sort by volume? fireform first then use cream of wheat or something to sort by volume?
 
crout, get yourself a good outside neck turner. I use the Forster attachment for their case trimmer. Others prefer the hand held unit.

Just clean up at least 70% of the exterior of the necks. Trim them to length. Deburr the flash hole. Chamfer the necks. Case necks are rarely ever perfect no matter the brand.

If the brass came from the same lot, just shoot it. Weighing it will be a waste of time. You can measure case capacity but do it after fireforming. I use a very fine gunpowder. Water is a royal pain. I dbubt you will find any difference in the case capacity.

I leave my cases as long as the chamber will allow so there are cases that vary in OAL at first. No biggie. After a few firings, I will trim to just off the max chamber length like 10 thou. That helps to minimize chamber erosion during firing.

I have been using 1F Win brass over the last 2 seasons. With the prep above, it has shot superbly. Likely it came from similar lots of Win ammo. I just keep an eye on any rd that tosses a shot. I mark that brass and if it tosses a shot again, gets trashed. So far, no issues.

Case annealing is your next big hurdle to maintain your neck tension.

Good luck...

Although I use IVI, Win and LC brass exculsively for my 5.56 carbine, I must admit that my favorite brass is the LC stuff. It requires some work before loading, removing primer crimp etc, but the brass is excellent.

Having said that, I will use all three types mentioned about with great results. Win is great brass and my standard for all my pistol calibers and rifles. I do like other types of brass for certain applications.
 
Ive used IVI, PMC, LC, FC, WIN, RP, Lapua, ect.

Im not picky when it comes to gopher rounds.

But I have found the most consistent in a given load to be Win and Lapua.

of course I dont have very scientic methods...also case life seems to be better compared to other brands.
 
I have Lapua and Winchester stuff.
I will get out the measuring gear out to see what the differences are....My money is on the Lapua.

If you have the time to blueprint the brass I don't think it really matters....I don't...Hence the Lapua cases!

If we are talking gopher gut piles then Lapua is a waste of money.

If you match prep your domestic brass you will throw quite a bit of it in the garbage can...At least I do. Also Lapua brass normally lasts at least twice as long as the domestic stuff....So there is some sense of economy (it is still expensive) to go along with better quality.
 
I didn't realize winchester was so popular. Lapua of course would of been me first choice if i had the spare cash and didn't already have access to other 223 brass.
