.20 Practical cases

[nmkid]

My .20 Practical build is starting. I have about 1000 once fired and 100 new WW cases. I also have about 1000 LC mixed cases. Is either brand better than the other? If I was to use the LC cases would I have to sort out by years?

I have used both types of cases and in my rifle with the load I'm using they shoot same point of impact from a 1-11 twist Pac-nor barrel.
My rifle does not seem to be fussy with Winchester and LC brass. I prepare both the same when forming the necks.
I have been very happy with the accuracy I'm getting which has been dime size groups at 200 yards.

I use mixed year LC for my 24" 3p 1:10 BHW barrel with excellent results. I buy the brass by the thousands for my service rifle and keep a few hundred for my .20P, I do not want to sort it lol.

Well, good! I think I'll follow suit and try the WW brass and the LC brass. Hopefully there will not be much, if any difference.

For accuracy sake, and maybe a little safe insurance, you may want to sort the brass by headstamp after you process it. I have lots of brass and there is nothing wrong with shooting mixed lots, unless you are running near a max load. Minor differences in case capacity can take a load from mild to wild with a variation in temperature. I went thru several hundred 7.62 cases the other night, sized, de-primed, de-crimped, cleaned, etc. Then I sorted them by headstamp just to make myself feel they were closer to being similar with each other.

The LC brass can be sorted by year and call it good. The winchester brass can be sorted by the headstamp and/or by weight.

If you have a .233 neck, Lapua will run .231" after seating a bullet if you are sizing down. I find no difference in WC of cases between IMI, LC, and FC. I tend to group by headstamp buy not year.
