Sorting 9mm Major Brass by Mfgr

[Hi-Power Jack]

After a year of reloading for my 9mm major

with range brass, I've just started sorting by

manufacturer (really mostly Winchester vs

any other, although I'm keeping the Remington

out separate as well).

Not sure, though, if I have a Winchester nickel

plated brass, is that The Same as the Win brass,

and can I throw it in together? Or are the

dimensions slightly different (different powder

capacity)?

I chrono'd five rounds of the sorted brass and got

Very close velocities (TruBor with WW brass,

115 gr Montana Gold JHP and 8.5 gr HS6 at 1.15"

OAL). Have to wait for the rain to end to try another

larger batch of same cartridges.

My last batch (last year) with Zero 115's, unsorted

range brass and same powder, OAL - velocities were

all over the place, but accuracy was very good???

Hmm, I've been sorting my 38/357 brass as well. I don't have a crono so I can't evaluate it that way, but with the off brand I can see a bulge in the casing at the base of the 148 gr double ended wadcutters. It is so thick that they won't fit in the .357 case gauge. I have been shooting them up in my S&W M&P 340 snubby. They will not load into my Ruger Security Six.

I haven't had any problems like that - matter

of fact, I haven't had any problems with unsorted

brass except the velocity seems to vary quite a

bit - but it didn't seem to affect accuracy???

I sort my brass also. I doubt that as long as you staying with the same manufacturer you'l see much velocity deviation between brass and nickel cases. The biggest velocity spreads come from mixing brands. I have also started cleaning my match brass with an ultrasonic cleaner before tumbling and have noticed velocities have been much more consistent. I actually won a beer at the last major match chrono.

I'm not familiar with "ultrasonic cleaning"?

What is it? What does it do better than just

tumbling? How much does it cost for an

ultrasonic cleaner?

It's primarily used for cleaning jewelry. Mine heats a cleaning solution and vibrates in an ultrasonic mode. It helps clean the insides of the brass. What it doesn't clean, it loosens and the thumbler gets it out. You can do a search, they range from 75.00 and up. It's not really practical to use it for a lot of brass though, that's why I only use it for major match ammo.
