Take a look at my DATA and tell me what you think:

[skip AI]

I weighed 10 random empty .25-06 AI cases today, have a look:

WINCHESTER SUPER X BRASS:

185.0gn
182.3gn
184.7gn
186.2gn
182.3gn
182.7gn
181.9gn
182.0gn
182.9gn
183.4gn

Variance of 4.3gn.

WINCHESTER LR PRIMERS:

Variance of 0.2gn.

NOSLER 85gn BT:

Variance of 0.2gn.

MY HANDLOADS (Brass, Primer, Powder and Projectile):

Variance of 6gns.

I weighed some .243 HANDLOADS (Brass, Primer, Powder and Projectile)
I made for repairman and got a variance of 2.7gn using REMINGTON brass.

Conclusion: ? Swap to REM brass ?

What do you think?

TIA

Here's my thinking (being a velocity hawg) and 25-06AI implies velocity /ubbthreads/images/graemlins/cool.gif

If my brass choice is Win or Rem I always go with the Win. I sort 100 to get maybe 50 of either brand. Win is lighter and has more case volume allowing more powder which usually results in greater velocity.

Accuracy has always been as good as necessary. GG sorts many cases to get a few. He also sorts primers and bullet weight and bearing length. I don't go to that length yet. But he hits chucks at the horizon and I don't /ubbthreads/images/graemlins/blush.gif

Guess I ought to change.

You may wish to compare Win and Rem cases but I wouldn't recommend a top Win brass load in a rem case. Could be a bit sticky.

Just my tho'ts.

Are the "random" cases deburred, flash hole reamed, neck turned and trimmed already?

I have never had good luck with winnie brass mayself.

Thanks for your input,
The cases are neck sized, trimmed to length and deburred.

The Rem brass seems to be more consistant even though weighing the loaded weight was probably not the best way to get a strong conclusuion.

I was worried about there being a 6gn difference and even a 7gn difference in the overall weight of the 25-06 AI handloads.

I have sorted the loads and have seperated the ones that are over 5gns above the weight so they can be dismantled.
