I will Thanks!

Thanks! I need recommendations for a case trimmer (manual for the time being), if you can provide me with one. I already have Calipers, but I wil look into purchasing the headspace kit.

Trimmer... I use the CTS trimmer attached to a portable drill

Calipers... Harbor Freight calipers have treated me well, I did check them across a feeler gauge to make sure they read true.

Here are a few reasons why you should get a headspace kit...
Increase brass life
Increase accuracy
Increase safety

Not bumping back shoulders enough can cause feeding issues, common cause for a stuck case.

I find setting up dies per the instructions, you are more likely to bump shoulders back too much... which promotes headcase separation.

On my bolt action for example, if I setup my dies per the instructions and get full cam over, I am sizing them back about 0.004 to .005 in excess. I bump back my shoulders no more than .001" for my bolt action, more for an autoloader...

Safety and making reloads setup specific to my chamber is reason enough for the kit.

Examples of headcase seperation...

What I find funny is the fact that harbor freight calipers are the ones that I purchased.
I have added the headspace kit to my cart and will purchase it.

Received Everything today. Now I just need to purchase primers. One quick question, How do I get powder that is stuck on the inside out. I am using Winchester 748 so I know that it has a tendency to stick in measures

Powder won't stick in measures. You will get a coating of graphite, it is of no concern. You always throw a few test charges and then dump them back anyway. A 100th of a grain of one powder in 5-6 ounces of another is nothing to worry about.

No seriously it is sticking to the metal in the measure

[Nickbowen5]

I can see the powder

You probably need to degrease the drop. A slightest coating of oil (put there to inhibit rust after manufacture) will cause all sorts of problems.

Take it apart and use a solvent like acetone that won't leave much residue. Wipe it thoroughly with a clea/dry cloth after degreasing before reassembly. Then cycle about a pound of 748 through it to get the graphite coating Geoff was referring to, everything should be jake.

[Nickbowen5]

I think that's what happened I took a dry cloth and got some oil off and then put a dryer cloth through it to make sure there wasn't any static then let the thing sit overnight
