308 LEE CASE LENGTH GAUGE

Hi guys, greetins from spain, I have a problem.

what is the exactly size of case length gauge & shell holder (LEE tool, hand trimer)

thanks a lott ,

Here's a Lee Case Trimmer which includes, left to right, stud that I put into a varible speed drill, case holder that screws onto the stud, pilot shaft for a .308 (.308 case above) and the cutter which the pilot screws into.

Works well for me.

Madrid:

The length to trim you cases to is 2.005 inches or 50.927mm.
The Maximum length for 308 cases is 2.015 inches
or 51.181mm (7.62x51).................DJ

I wasn't sure what he wanted.

With the Lee, the pilot determines the length and you don't have to worry about it.

Maybe now we have covered all the bases.

Madrid, I've found that the Lee case trimmers cut cases a bit shorter than really needed.

You can adjust the length of the case by turning the case length gage out a bit from the cutter.

Once you find the desired length, use some Lok-Tite (blue) on the threads of the case length gage to the cutter.

This setting will change as the tool wears. So check often with a quality caliper.

Thanks guys


Bill Mc & DaMan but what is the exactly size of case length gauge .

Can you measure it for my???

After trimming the .308 case it should be 2.005 inches long.....or 50.93 MM long.

It should not exceed 2.015 inches or 51.18 MM long.

Madrid, here is the minimum length it can be. Do you need an actual measurement from someone? I am curious, do you need to modify something or create something?

This is the way I would go about setting a Lee case trimmer....

1. Resize the case to desired fit in chamber.

2. Turn the case length gage hand tight into the cutter until the shoulder of the cutter contacts the cutting 'blades'.

3. With the shoulder of the case gage contacting the blades of the cutting tool, take a caliper and measure from the rear end of the cutter to the tip of the case gage. (I find this measurment more consistant and accurate than measuring from cutting blade to tip of case gage).

4. Trim a case with the Lee cutting tool, use chamfer tool as normal, and then measure overall length (OAL) of case.

5. If the case length is shorter than desired, put Loctite Blue (thread adhesive) on threads and adjust case gage and cutter to desired OAL using your caliper to measure from rear of cutting tool to tip of case gage before the Loctite sets.

As you use the tool over extended time (thousands of rounds), the case gage tip will form a slight dimple in the lock stud and cases will get shorter.

If this occurs, use a pliers or vise-grips to remove the case gage from the cutting tool. I use a small section of bicycle intertube to protect the case gage when doing this operation.

Apply Blue Loctite to threads, set the trimmer to desired length, and you are set to trim another thousand or so cases before you need to adjust again.

that might work for one caliber but I use my Lee ttimmer for:

.44 RM
22-250
7.62x39
.308
30-06
7mm RM
8x57

7 pilots and one trimmer and one stud.

One problem with the Lee trimmer that you have to watch for is that the case holder is too soft. I had one that after a decent bit of use started trimming cases too short. The point of the caliber adaptor had swaged out a hole in the base of the case spinner enough to make it trim cases a few thousandths too short. Not enough to be dangerous but annoying nonetheless. It's another case of Lee need to use a little bit better materials and harden them properly................DJ

I have one of those tools that I used for many years. Mine trims to 2.010". Went to an RCBS rotary trmmer when I started shooting competition for no other reason that the volume of trimming involved.

PaPa 260

I found that the stud left the cases too long. A quick trip to the grinder and took off a few thousandths from the pin on the end and perfect length came about. It's kind of a joke that there are so many studs out there....you could have different length stop pins and use the same one for alot of cartridges.

thank you
