7.62x25mm from .223 loads

Wow! You are talented, ammo manufacturer, cameraman, directer, producer & actor.
But, are those your hands or hand doubles imported from India?

All kidding aside, you did a great Job!!

Question about using the N size drill bit...

I don't have a drill press and cannot drill out the resized casing. I made a dummy round (with a .308 bullet) and it chambers and extracts out of my Tokarev when cycling by hand. (sized the cut casing and flared the end with the die set. Then trimmed the flared case)

I'm assuming that there would be a spike in pressure if the round was too tight in the chamber. So, if it chamber and extracts by hand it's probably ok to try it with some lighter loads.

Is the reaming with the N size bit only for use when using the .311 bullets?

Do I need to slug the barrel?

Thanks for advice

no drill press here either

I only reamed out my .223 cases with the N guage drill bit
because that's what I read to do. Had to put them in a
spring clamp and sloppily ream them out with my hand drill.

I also was able to put a .308/.309 bullet in an unreamed
case and have it hand chamber in MY Tokarev pistol.

Just start low and work up in .1 grain increments, making
a few completed rounds at each level. Don't be in a hurry and start
making big jumps in powder levels.
 
Not all 7.62x25 cases made from other calibers need to be reamed with a N drill. I made 40 cases out of DA and IVI 9mm brass, 150 cases out of TW72 223 brass and they did not need to be reamed. Made 150 case out of FNM 223 brass and they had to be reamed wiith an N drill. The method I used was take a case fired in my gun , measure the O.D. of the neck of the case. Take one of my new cases and seat a .309 slug, measure neck diameter of case, if new case with .309 slug is 2 or more thousands smaller than fired case neck size then you should not need to ream the necks of the new cases. After loading your new cases for the first time check neck diameters to make sure all ammo is at least 2 thousands smaller than your original fired case. My loads in my TT33 are,5.0grs. Bullseye or 5.7 grs. of Dupont #6 powder, CCI small pistol primer, 78gr. hard cast .309 dia. slug. This load is the lightest I can go in my gun and have totally reliable feeding. I have fired over 500 rounds of this load with no FFT or FTE and some cases have been loaded 5 times with no case loss. This load will shoot as accurate as I can.

Great info. Once a person gets into it, this .223/7.62x25mm case
conversion isn't as daunting as one first expects.

They just need to make some dummy rounds and hand chamber them first
to see if they need to ream out the cases or not.

I picked up some striper clips from the range yesterday for the Russian round that i can use for my .223 cases and i wondered if somebody has tried resizing .223 cases to the Russian round and here you are
