6mm-223

That sounds good. Do you want to try some of the 87 or 90 grain bullets?

Lets try the 75's first, then we'll work up. My gun hates anything above 80's.

Looks like you need to stick with Federal. I was very surprised by the Remington deviation.

I agree about the Federal; here are the groups shot at 100 yds( red dot is 3/4"), #1 is Win (called flyer) #2 is Federal $3 is Remington & #4 is CCI

I wonder if full length resizing might be adding to the velocity spread.

Why do you think FLSing would cause a velocity spread??

a couple other things...

Dies, i run redding, but I use a small base FL sizer to resize first for first neck up. Then I run the FL 6x45 resizer to make sure that they feed when I neck up from 223.

I make sure that all cases are chamfered/reamed with no nics or dings. Same with the primer pockets being cleaned, and flash hole. I do this because it's a bad prairie dog habit with my 250's. Cleaning brass prep is 3 shots (slight chamfer/ream on every one), with crushed walnut, then on the 4th, into the Stainless steel media tumbler to clean the insides.

I can load up a couple rounds with my 75vmax's (8208/BenchMark) and see if they run in your guns using my method if you want. I'll try and dig up my latest target, but it was on a windy day, and I'm really happy with the grouping considering the crappy weather.

That varget load should shoot, i'll duplicate the powder charge, chrono all loads and see what I get for groups or patterns.

The redding die part number is:
MM/223 Rem (6MM x 45) 80312

I use Redding Dies for my 6x45

This brass is brand new, weighed, sized, tumbled (fine corn cob), trimmed, primer pocket uniformed, flash hole deburred, chamfered, then final tumble. Sounds like we have the same method; if I'm doing something wrong, someone let me know.

Maybe we should get together sometime at BenL. and figure out what's going on. I could bring my single stage press and components and we could work on some loads while there. This crap drives me nuttz. I only shoot the 75vmax's.

I agree; it's been driving me nuts for a while now.

If you want to get together at Ben Lomond sometime that would be fine.

I'll PM you my contact info.

here is a ten shot group from today with Federal primers, 25grains 2015 and 58 grain Zmax.

Spread of 58 fps

I'm not convinced there is s code to be broken; when it comes to accuracy, compromise is a dirty word.

i was gonna hit the range today, 2 much wind where i'm at. Tomorrow is out, gotta scout elk land tomorrow with my bro-in-law. I hate this garbage wind, everyday i want to hit the range, guess what...WIND!!!

I know this is not a definitive test but I backed off my Redding resizer die by a 1/16" to see if it would have any effect on the velocity spread (don't have a neck die for this caliber.) I loaded 10 full length and 10 "backed off" and went to the range today. Posted here are the shot groups with respective velocities. As a note there was a 5 to 10 knot right quartering tailwind.

I am wondering if my chamber might be a bit on the large size in comparison to my die?

I brought my 6 up to the range today, but didn't shoot it because of the wind...My 300wb at 25yards didn't have much of an issue...Every frig'n time i go to the range now with that 6x223 it's windy...I'm done shooting in the wind trying to get groups...
