6mm-223

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

[buckshotbarlow]

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

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

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

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

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.

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

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 talked to eneranch today about his BHW tube, and we're seeing the same problems. I'm going to try and get some 67 gr vmax to see what the hell they do. Also, gonna try some vvn powders either n135 or n530 to see if that does the trick. The velocity looks decent, but I think we are suffering from a ok barrel manufacture. I might have my gun smith set me up with a swap barrel for my savage.

One other thing, I'm gonna hit the range with a better scope next time. My 6-18 leo is gonna get bumped for a 8-32 mueller or burris. At 300 that should assist with load development. I have to get his gun ready for sept1, after dove hunting, the dogs might come out to see what the hell is going on...

Well let me know if you all break the code. I am going to play a little more with 8208. I also ordered a neck sizing die, but in the mean time I might try backing my fl die off a 1/16" and see if it has any measurable effect in velocity spread.
