Reloading 7.62x39

[Superman]

Thought I would try my luck with reloading some. I have reloaded pistol calibers before but this is my first rifle caliber. Bought some Lee dies, came with two decappers 307 and 310, but they actually measure .308-.3085 and .3105-.311 bullets I have measure .310-.3105, so they are way to loose with the 310 decapper, can't feel the bullet pressing into the case at all. Once they get to the cannelure it is extremely loose, you can pull the bullet back and forth 20-30 thousandths. So I guess I will try the 307 decapper and see how that goes.

Anybody else experience this?

307 decapper worked out great

What does your bore measure? Those .310 bullets might not be big enough.

[Superman]

Romanian barrel .303/.3135 US Barrel .3025/.312

All 7.62x39 bullets I have found are listed as .310, except berrys plated bullets listed at .311

I always turn any mandrel down a few thousandsandths more. I think it holds the bullet as good as a crimp without deforming the bullet. For what I do I want the best accuracy so I think my way is better than applying a crimp.

I used to reload 7.62x39 and gave it up. I am having a custom bolt gun built in 7.62x39 so it is back to reloading. The bore will be .300"x.3085" so I can use .308" bullets. I can also shoot factory ammo without any issues. I plan on loading HEAVY bullets. Before I loaded 180 grain bullets for use in an AR.
