.308 resizing question

[bigbossman]

I just didn't know if there was a difference between full length and small base

It's in the name.

[sigstroker]

Pig was walking straight towards me--bout 45 yards out. Was a good shoot----scooted him backwards a ways then he turned and ran off. Was hunting a ranch in Texas--they weren't real happy I was using a 223 as they frequently have problems with people using that caliber. They lose to many with a 223. The first one I got went 150 yards before it keeled over---straight through lung shot. Second was an eyeball shot straight in and shattered the neck. Third I never found and the fourth was the forehead shot. Was a good time!

Reloads? What bullet and roughly what velocity?

Small base sizing die should have worked. I use FL sizing die.for 308.
Sounds like you didnt check your brass to see if it would chamber after sizing.
I use a case guage. I would pick one up and check your reloads.
Sounds like you didn't have your die adjusted correctly.

Per my post---I case gauge 100% of all my loads---rifle and pistol.

I am thankful I do not have all of the problems other reloaders have. I have case gages, I have chamber gages. If I have a bolt that will not close on a case I can measure before opening the bolt. And then I can determine if the case was sized before I lower the ram; to full length sized the case the die must contact the top of the shell holder.

When it comes to sizing the only press that will bump is the cam over press, if the press is not a cam over press it will not bump; if it bumps, it bumps twice.

Factory Ammo---PMC 62 grain hollow point skipped right up off his forehead.

Per my post---I case gauge 100% of all my loads---rifle and pistol. They shoot perfectly in the Semi. I loaded for the semi then purchased a bolt. They still case gauge but the bolt wouldn't close. Nothing to take apart as I have 800 more to load but will re-size the brass first. The question is the difference between full length and small base dies and if t makes a difference.

Thanks

Your case gauge is not correct for your bolt rifle.

Some case gauges are not made to minimum body diameters as they are only intended to check shoulder length.
So if you are using a case gauge that is larger case body diameter than the rifles that you want to use the ammo in, then the gauge will not tell you if the ammo will fit the rifle.

Also, your semi-auto rifle may have a longer chamber than your bolt rifle and the way you have been using the case gauge, you don't actually know what your shoulder lengths are.

Do you have a protrusion micrometer or some sort of measuring tool that measures how much the cases stick out of the case gauge?
If not, are you just going by eye and feel when you gauge the cases?
How accurate is your eye and fingernail?

Because whatever method you are using, you have just proven that the method is not accurate enough.

Sounds like my Rockchucker is a cam over press. I've been doing the "cam over" thing for a couple three decades without knowing it was an official "thing".

Your Rock Chucker is not a cam over press, The Rock Chucker is used with the Piggy Back 1 and 2 press. The Piggy Back attachments have a one way clutch. Means nothing to a RCBS reloader because they do not know what a one way clutch is; but, the auto advance features of the Piggy Back will render the one way clutch scrap if the ram reverses.

I understand it is a mind bobbling thing. Order a one way clutch for the piggy back attachment from RCBS. They will not have one; outside of RCBS i doubt you will ever find a reloader that knows what the anti-back up devise is for.

Over six decades ago RCBS furnished directions with their presses. I have 3 Rock Chuckers, I have had 5, none of them cam over. All of my Rock Chuckers lock up, jam up etc. because of the linkage. The Rock Chucker is limited, problem, no reloader will look under the press to determine why the ram is shoved forward at the top and back at the bottom. I am very happy with the way my Rock Chuckers operate without camming over.

If I wanted a press to cam over I would use one of my Herter presses, they all cam over, I have at least 14 Herter presses.

AFAIK, it's not an official "thing."

Unless you consider something being an intentionally created feature engineered into the design. OFFICIAL.

Fred Huntington originally designed the [ROCK CHUCKER] to swage bullets with.

Which he then shot at ROCK CHUCKS.

Please. Calling something "official"?????
Get over yourself, and get a sense of humor.
I built reloaders at Star Machine Works, and I know about going past center with linkages. Some of their machines were designed prior to WW2.
I also know about someone calling a .025 taper straight.
I've attached pics of a couple of my tools.

Please re-read what I actually wrote. Before you chose to incorrectly paraphrase what [you seem to think I wrote].

Focusing specifically on THE FIRST THREE WORD OF MY POST. Which is definitely NOT ME CALLING SOMETHING [OFFICIAL].

And as to the 1st underlined in YOUR post. Seems like, as well as working on your reading comprehension. You might take a chill pill so are not so quick to trigger, and give ill mannered advice over your own lack of understanding.

Apparently you also missed the BIG GREEN GRIN SMILY ENDING MY POST.

2nd underlined; .... .308 win cases, do have a straight tapered profile from base to shoulder. With a dia. difference of .0163 in. So I do not see the significance of your .025 mention.

Care to elaborate?

As Pacrat already posted your small base die is just a full length die with a tighter base dimension.
When you size the base smaller the brass has to go somewhere so it moves forward.
When that brass moves forward the shoulder the neck or both get longer.
If the brass won't fit in your new gun the shoulder or the neck is where to start looking for your issue.

It is official, RCBS said the the Rock Chucker was a non cam over press. They also said the Rock Chucker press was not a bump press, they also said the only press that bumps is a cam over press.

It is in the book, no one has a book and then there are all of those reloaders that do not read.

And then there are all of those reloaders that chambered their 308W chambers to 30/06. The 30/06 reamer will not clean up the 308W chamber.

it wasn't the shoulder or the neck----it was the base. it was 10 thousandth's over right at the very bottom of the brass. There was a third of a turn available to lower the sizing die that rectified the problem. But I Do appreciate all the help.
