Lee 452-230 TC OAL Help

[Papucho]

I´ve just made 1500 perfectly good boolits out of this mold and will be loading them up soon. But it has been difficult to find data on OAL for this boolit. Anyone who uses it that could help me please? I´ll be using W231.

I use to use 6.0 grains W-231..I now use 5.0 Bullseye. I use this in my Marlin Camp Carbine & my Ruger Blackhawk. My Chrony says that I obtain 924 FPS muzzle velocity through the Ruger---using the 6.0 W-231 grain load.

Thank you John Boy. So can I use LRNFP OAL for TC Bullets?

[35remington]

If this is for .45 ACP, overall length should be more like 1.220."

[Papucho]

Yes. I´ts for 45 ACP.

So can I use LRNFP OAL for TC Bullets?
Yes - it's the specific weight of the bullet for loading data - not the shape of the nose

[flinchnjerk]

C.O.A.L. 1.210 works in any 1911 in which I've seen it tried. With regard to your using RN data when selecting a powder charge, bear in mind that there's more shank (read less case volume) to the TC than there is to a RN. Approach maximum loads with caution.

Yes - it's the specific weight of the bullet for loading data - not the shape of the nose

wrong....LENGTH DOES COUNT AS IT WILL CHANGE USEABLE CASE VOLUME..AND PRESSURE.

max oal for 45acp is 1.275.....

my guess is that mr john posted 45 long colt data............


IGNORE IT...

SEAT ONE BULLET IN A SIZED CASE....AT 1.275...TRY CHAMBERING. KEEP SHORTENING TIL IT CYCLES WELL IN THE GUN.
THEN ADD SOME POWDER.....LOOKING FOR ABOUT 750-800 FPS.
USE ONLINE TOOLS FROM WHOEVERS POWDER YOU ARE USING.

I measured my TL452-230-TC's max OAL in my Government Model by the usual method of marking a rod inserted from the muzzle to the breech face, then inserting a boolit till it stopped in the rifling origin, gently inserting the rod again and marking it again at the muzzle. I forget the exact measurement, but it worked out to the point where the base of the cone is right at the case mouth.

Mike, you are absolutely correct. What I missed was the OAL, aka COAL part of the question. :oops:

Mike, you are absolutely correct. What I missed was the OAL, aka COAL part of the question and my mind was thinking weight. :oops:
