what does CUP mean?

ejpaul1 · 06-19-2005, 10:01 AM

My lovely wifey just got me a re-loading kit and I was looking through the manual and saw a listing of CUP instead of the velocity. I know it has something to do with pressure but does this coorilate directly to a velocity? I kinda need to know this before I start re-loading. I do want higher velocities. Let me know what you think. EJ

CUP is copper units of pressure.
In the old days they used the crusher method to tell pressure.
Find a older Lyman reloading book ,it explains how that mothod works.

Some were there should be a fps .

I am loading 30-06 stuff. Probably 165 and 180 grain boat tail. I want to know what is a good powder to use and what is a good load to use? How many grains? I am soooo new to this. EJ

You can't go wrong with IMR 4350. I normally load 58 grains for the 165 Sierra BT, and 56 for the 180 Sierra BT. These loads were safe in my gun, but they might blow yours up. Check a reputable loading manual first. Start low and work your way up. Get some one who has done this awhile to help you. It ain't rocket science, but its not all that easy either - at least at first.

or IMR 4831 , both seem to be the "standby" powders for the 06 stuff.

Buy a reloading manual and read the front section ,they all have a how to area .

I dont think my gun should blow up, it is a brand new model 700 remington. It might though, who knows. Good advice, I think I will grab both of those powders and load them up to see what is the good recipie. How many times can you use brass? EJ

06's if loaded moderately, can last like 10 times. But I like to toss it after 6. I think the necks get too thin. Remington brass with all its faults does last a long time. I like Federal brass for accuracy but its soft and thick. Usually the primer pockets will die after 5 shot.

Hmmm, sounds good to me! I like the affordability and the customization factor of reloading. Anyway, I am gonna load up about 100 this week and we'll see what happens. I finally did find the velocity in the manual. Sweet! EJ

Don't load up 100 at once. Been there and done it and end up having to disassemle half of them. Load up small quanities to start to work up your loads and find the most accurate. When you are sure you have it, then mass load.

I like to get all my brass preped however. So I might buy a bag of 100 pieces and size it, trim it, deburr it and prime it. That way its ready to load at a moments notice.
