Weird powder burns On target

[cigarbufff]

Hey guys and gals. So here is the situation. I have a savage axis in 223 and I loaded some reloads for it. (25g of Varget behind a 55gr pill)when shooting I noticed it Left behind powder residue on The target.

But then when I shot With my AR. (norinco) it didn't Leave anything.
You think twist rate has something to do with this. Thanks in advance.

Bolt gun vs semi, one bleeds off the gases and crud while the other doesn't? Just a guess.

At what distance?

 

[cigarbufff]

30m/50m

Do you get the same effect if you just cleaned your barrel?

Lead round nose bullets? I have seen the same marks at 50meters but not at 100meters using LRN bullets. Switched to polymer tips with the same load and it went away??

No these are copper jacket Ed frontier bullets. This was with a clean barrel

Try different ammo, I’m going to guess it’s not powder but lead fouling maybe something to do with the extra velocity out of your bolt gun.

Different ammo doesn't do it. Just my reloads

What's Your powder burn rate??

Read post 1.
Nothing wrong with Varget in a 223.

Those marks on the paper are called "comet tails". They are lead coming out of the bullet as it is in the process of disintegrating.

The Frontier CMJ bullets are plated and likely not a robust as jacketed bullets. My guess is that the longer barrel of your Savage is pushing the bullets past their limit in terms of velocity and rotational speed. I would test this by loading a few rounds with a lower powder charge.

I was thinking it was the bullets coming apart but the only time I've seen it happen the projectile must have already desintegrated completely since they didn't even make it to the target (light varmint bullet pushed hard in an 7 twist), the holes in the pics here look like the bullet is still in one piece which threw me off.

I've heard of guys having issues with the plated bullets just haven't seen any pics.
I would go to properly jacketed bullets.
If it's not happening in the Norinco which has a 9 twist if I recall correctly I would burn off the rest of the projectiles you have in it and I'm guessing your bolt action has a 7 or 8 twist which is pushing these projectiles past their limit.
