Default Milspec 30 carbine loads

I'm getting ready to load some 30 carbine and have new armscor brass, armscor 110 grain fmj bullets and h110 powder. What would be the milspec powder charge for this? The sierra book seems to be pretty conservative. Thanks

Exclamation

A good load in this CMP article along with some important reloading tips:

http://thecmp.org/wp-content/uploads...Notes_2007.pdf

The load mentioned there pretty much match to a tee mil spec loads. Also note their recommendation to check length and trim after every firing. You would be surprised at how much case lengths will vary each time they are loaded and fired...even the same headstamp cases.

I found that Armscor 110 FMJ were a bit long on the oglive and required a little deeper seating than the typical 1.680" COL to keep from hitting the lands on both my Inland and Win Carbine. Hornady 110 SP were not a problem at the typical 1.680 COL.

Note: H110 and W296 are exactly the same powder so it boils down to which is more available to you in the future.

+1. And the cases sure do stretch, surprisingly so.

Default Work Up Slowly ...

Used 15.0 grains of H110 in 1965. But ... powder today may be better? Work up slowly. A good chronograph would be needed to determine actual velocities.

Yep .... Carbine brass stretches. Know your exact head space. Trim to suit. We trimmed to 1.285. We also full length resized but did not taper crimp. Enjoy.

15.0g CCI 400 primer 1974 fps
14.5g CCI 41 primer 1988 fps
15.0g CCI 41 primer 2037 fps

I originally started with 2400 powder.

However, after trying WW296, 15.0 grs. of WW296 with a 110 gr. bullet has been my favorite load. It functions well and gives satisfactory accuracy in all of my carbines.

My second choice is 15.5 grs. of WW296 with a Hornady 100 gr. semi-jacket.

And yes, WW296 and H110 are identical and interchangeable powders.

With a 110, 15.0 is safe. 14.5 works fine if you want a little wiggle room. I don't see any point measuring velocities in the carbine cartridge. This tells you nothing about pressure. If the action cycles and you can hit a dinner plate at 100 yards, you are there.
