Max load of 2400 in 7.62x39

[hylander]

Can't find load data for 2400 in 7.62x39
I don't want to run max but I'm at
15.5 gr. with a Lee 155 g/c and it is just starting to function the action on my Mini-30 and is accurate. SKS functioned at 14.5gr

Can't find load data for 2400

Usually with 2400 you will reach the point where accuracy will go away before you reach the max load.

I found 20 gr to be a max psi load (measured via Oehler m43 PBL in a Mini Mk X) in the 7.62x39 cartridge using the Lee C312-155-1R in cases using LR primers. However, as mentioned accuracy went south at about 17 - 18 gr.

Good deal Mr. Gibson and thank you for the info!

This is for the 7.62x39? Just to clarify..


I always thought around 16gr of 2400 with 150-160gr was a max load for this cartridge.

16.0 grains of 2400 with the rcbs 30-165-Sil bullet (.309" diameter) has been my max load for that powder. I shoot two different bolt actions (both with a .308" bore), but I bump up the bullet diameter to .312" with powder coating for my SKS, and the 16.0 grain load is also max for it as well. Accuracy begins to drop off at 16.5 grains, and takes a nose dive at 17.0 grains. Plus, at 17 grains the SKS launches the empty cases off into the next county.

Thanks Larry,
I'm hoping 16.0 will do it in the Mini-30
Accuracy is good at 15.5 but does not always eject. SKS functions at 14.5 but just barely.

I seen that and was just double checking. Maybe he mistyped since that's ALOT above what I had previously thought a max charge was.
