I don't shoot competitions and I can tumble brass quicker from beginning to end using my current method. One buddy has the steel pins set up, and his brass is shiny. My groups are as good or better than his, all sub 0.5" at 100 and consistent out to 600. An elk will only be so dead.


Shiiiiit . . . you're no fun. :cussing:

Duh? ;). Unless you enjoy porcupine hunting.

Half hour tumble to quick clean, then size/deprime. Trim. Clean off lube. Let dry 20 minutes. Polish tumble for 30-60 minutes. Prime and store until it's to to reload. My tumbling/drying time is fairly short with reasonable clean brass. In the time that my two tumblers are full I'm loading something else. Cruddy brass gets to tumble overnight.

I don't disagree that tumbling produces shiny brass, but the shiny brass doesn't matter to me enough to buy additional gear. Maybe some day.

Yeah, I agree that there's no practical value to wet tumbling.

But even as a narrow-minded emotionless engineer, I do it anyhow because it's so darned pretty. :prettyeyes:

the cleaner the brass the easier it is to inspect.

but yeah not really worth it other than the brass always looks new.

Loading LC 308 with small base die set. When I opened the die case- no neck expander. So I pulled out a 30-06 die set and took the expander off that one, put it together and back to the races.
After decap/resize about 100 cases I pulled out a box of bullets to check the fit. They were pretty tight. Like tight enough to make me wonder about a non-boattail.
Took a shiny clean but unsized one from the box I was doing, and the bullet slid in fairly easily.
Kind of weird.

Does the SB die set affect the neck any differently than a FL die set? I thought No- just tighter towards the base by .001" ish.

Did a search for a few things and this thread is the closest that I can find.

As far as I know, small base only affects the, err, base.

You are dead on Steve.

Only needed for brass that you can't chamber before processing.

People could save themselves a lot of money to see if that fired brass they have will chamber in their rifle before investing in the small base die. Exception would be if they have a small custom chamber in their rifle and bought a bunch of once-fired military brass. Almost a certainty that it's been fired in an automatic/semi auto weapon and a small base die will be necessary.

That said, I don't own a single small base die for .223/5.56 or .308 and have had no issues with cases not being sized enough. I've seen cartridges that have been crimped excessively and get stuck in chambers. All to often the first suggestion is "you should get a small base die" and when they do, it doesn't cure their problem. :bigsmile:

Quite a bit of my brass was MG fired. About 1 in 10 wouldn't chamber with FL die sizing. SB die fixed it. My question was about different affect on the neck, not about whether I needed to use a SB die.

The SB die squeezes brass more, causing accelerated stretching up the neck, or so I read. My question had to do with why my bullets didn't fit in the neck as easily as I am used to, and I thought it was odd timing to be right when I had swapped a 30-06 die for the expander.
