440 cal col!

Jasonzee · November 17, 2019, 06:58 AM

I am on seating 40 cal. All the other steps I did already. I am using Lee dies. Now my problem is this the book say a col of 1.125 so I set the plug in the dies after I made a dummy round to 1.124,the next was 1.117 it chamber in the gun but is that ok? I'm using 601gr of Imr 4064.

.007 isn't a lot of difference but usually I only see about .002 variance between rounds while loading. These variances are due to the bullets profile from bullet to bullet and is normal. Now if you were to measure from the ogive of the bullet it would be more consistent.

As you probably know when the oal is shortened the pressure goes up so be careful but I can't recommend if .007 shorter is safe, that's up to you to determine. If your at the top end of the load recommendation I probably wouldn't shoot it. If your in the middle then I wouldn't worry too much about it.

6.1 is the 2nd to the max. I pulled all the bullets and will start over. Thanks

Wait a second- you are using IMR 4064 in .40 cal? ( I am assuming you mean 40 S&W)

IMR 4064 is a rifle power!!

Good catch Mike! Early this morning and I didn't notice the OP was using that. Jason, don't do that brother... use only a suitable powder for .40

IMR 4064 is one of the most versatile propellant in the IMR line, used for 223 Remington, 22-250 Remington, 220 Swift, 6mm Remington, 243 Winchester Super Short Magnum, 308 Winchester, 338 Winchester Magnum

That's what happens when you more then 1 powder on the table! I should grabbed power pistol.

I'm betting it's not 601 or 60.1 grains either. The bullet weight matters too.
And IMR4064 is your friend, but not in a handgun cartridge.

Hornady 185 XPT bullet. I bought a different seater die the RCBC the die was not giving me good results when seating
I set it at 1.124 and the next round was 1.107!!!.
