you see a lot of British rifles that ended up in Australian service stamped with. D Arrow D or Dmilitary district ie 1,2,3,4,5,6 D , 3 would be a Victorian rifle . We also use still today a numerical prefix to represent what state you enlisted in ie my dad was a 1 for als and mine is a 2 for nsw

The use of 7.62x39 was mentioned here also. Read from elsewhere some use 7.62x54r pulled projectile and 80% of powder from the round to load 303. Yes, 7.62x39 and 7.62x54r are 0.311. The 2 groove barrel has identical serial number marking as on the receiver; the forearm stock also has the same marking. None bothers me, as long as I get some fun out of it. I loaded up 30 round using Trail Boss powder, be heading to the range next week.

I would be cautious of low density smokeless powder loads. Some powders are fine for this purpose (like 4895); some are not. Not likely we know what powder was used in the 7.62 x 39 cartridges. If it were me, I would use a known powder type and use minimum charge weights from published load tables.
Is the 7.62 bullet measure approx. .310? If you are using a Lee collet die, you can get an undersized mandrel from Lee if your not getting sufficient neck tension. The 2 groove is a bit of a mystery, I thought only Long Branch and Savage made two groove barrels, but perhaps other factories made them. |

Load density -
Low powder charge can cause secondary detonation. I reload 357 mag and 300 Blk near max using W296 or H110.
It is powder dependence. That's why I asked if you have any issue. Edited I use the Hodgdon recommended Max load * 60% rule using from Lyman handbook 48th Edition H4895 sample of 43.5 gr max for 125 gr projectile: 43.5 * 0.6 = 26.1gr. The average pulls 762x39 unknown powder =/25 gr. So, it is short of 1.1 gr; does it matter? I don't know. I loaded up 10 to try. BTW, I was surprised to see the Russian ammo from early 90 hollow point projectiles are boat tail.

I am not sure as to the problems associated with air space in smokeless cartridges.
I have never had any issues with just dumping the 7.62 powder load directly into the 303 case. What is your concern? Somebody here will have answers.

Check 10 of the pulled 762x39, powder charge average around 25 grains (whatever it is).
COAL set to 2.89". The Lee neck sizing does not seem to form the neck tight enough, might have to crimp tighter. I hope the reduced charge presents no issue on pressure. |

That is exactly what I am trying to do. Only concern is powder from 7.62x39 is only ~60% of case capacity in 303. If that works, I have lots of 7.62x39 from my AK. I am also planning on using Berry plated 125 grs bullets, and 12 grs of Unique powder.
