What’s going on here?

[mwkelso]

I had a similar issue when I went too light on the chamfering. I'm not sure which die set you're using, but it may be worth assuring that you have the correct bushing in for your brass. That is if yours can be changed... If not, then probably just chamfer.

 

[aushunter1]

Few things worth checking,
1. most obvious as already stated is the internal chamfer.
2. What is the inside neck diameter? Was there a brass or possibly a bushing or mandrel change? The "neck tension" may be too tight related to both items 2 & 3.
3. What is the state of anneal?
4. We're the necks brushed/and/or lubed prior to seating.
5. Was the bullet diameter double checked?
6. Have you used this bullet brand and p/n before? Are these bullets starting in the bullet seating die correctly?
7. Is the bullet seating die functioning as designed? Is run out excessive?
8. More obscure but has happened, were these cases tumbled after sizing (or even after chamfering) ? Were stainless pins involved?

Little things often add up to bigger problems, my best guess is chamfer combined with tight neck tension.
Good luck,
Randy

All good advice @MNbogboy but the problem when a person with 7 posts under their belt there is no way of knowing a persons ability or knowledge of reloading.

@ryanjohnson my advice is to stop reloading right now, go get a really good manual that explains the ins & out of all reloading practices & methods, read it twice before you start pulling the handle of the press again.

If you have missed such a simple step of debur & chamfering then who knows what else you have missed!

The cases don't look like they have anywhere near a sizing die?

No offence intended but you are playing with explosives mate, Im just thinking of your safety!!

+1 on the process! I was dropping loads this morning and almost doubled-charged a case. I would have known by the powder not all falling in to the case, but the same concept still applies.

LOL! It reminds me of this thread https://www.longrangehunting.com/threads/hammer-bullets-compressing-my-powder-charge.238857/, esp. OP's comment on #87.

Very true, we do all form processes & you have to do things in the right order, sure you can make a mistake but if the process steps are in place its less likely.

Sure I have made mistakes but I know I have made them, called myself an idiot & gone back & fixed them.
Thing is you have to be able to recognise your mistake before it blows up in your face

Lmao it does sound similar

Its just to frequent, people trying to do the marathon before they can run a 100m dash

As usual somebody here made a helpful comment and was instantly bashed applying upper end precision reloading techniques to 308 hunting ammo. Yes shaving the bearing surface will affect accuracy. But if the OP is new enough to not know what caused it, it's highly unlikely he's doing ELR or bench rest. ESP with a 308.... so maybe ditch the ****ing contest? The fella you attacked was doing nothing more than helping. @CatShooter.

This toxic BS is what drives people out of the sport.

so some magic has the case shaving from the sides but never touched the base ??? how did the base miss ? the crown sees the bullet dia at the crown, not any taper/boat tail.
no i think you have lost the art of learning and are trying to pass it on to others.
shooting in benchrest and winning in benchrest are 2 different things. I have wins.

 

[VLD Pilot]

The suggestions on what to do to rid the shavings is probably spot on. Depending on how many you loaded and if the barrel is brand new, you could use the first loads for a break in load. Otherwise scratch it up as a lesson in reloading. We've all learned by trial and error in some cases. If (and I'm not sure based on those bullets if they are TMK or TGK bullets)they are hunting bullets, you won't really see any accuracy issues. You'll at least form some brass and get some range time in.

 

[Alibiiv]

I did chamfer them must be not enough. First time this has happened to me ever. Are the bullets I already seated ok to shoot and do you think it will effect Accuracy? Thank you

From the photo it "appears" that the neck has not been chamfered enough leaving a sharp edge and shaving the jacket on the bullets, Curious if you did anything like change brass or bullets. The bullets that you've loaded look like Nosler bullets, the jacket on Nosler are pretty resilient and usually will not shave unless something is not done properly. Also are the casings new or fired? And.......one suggestion is to purchase a Sinclair mandrel/expansion die for your neck sizing. It adds an additional step in the reloading process, but the results are well worth the effort when one considers the improvement to the sizing of the neck for neck tension and also improves concentricity of the reload. You will have to remove the expander plug before expanding the case necks, and....then pass the casing through the Sinclair expander. The Sinclair die is caliber specific, however for what you get out of the die well worth the investment. I reload Barnes bullets, their jackets are a bit softer, as a result they too would have a tendency to shave when seated, the Sinclair die helped to eliminate the shaving. The Sinclair expander makes the neck tension more uniform and also elimanates the dreaded donut; I neck turn so shoulder expansion is not an issue.

Just as a general rule any time something happens out of the norm stop what you're doing immediately and find the reason it might be important and save you from injury

That is very good advice, stop immediately and find and fix the problem. And do not ask questions in forums unless you have thick skin.

I'm glad I started reloading in 1973 after I got out of the military. They didn't have the internet then so you would ask a reloader friend at work that gave you polite answers. If they didn't give you a polite answer you could smack them in the mouth and then find another reloading buddy.

Moral of the story, don't ask questions in forums when the people answering have been locked up with their wife and kids for over a month. Some of the people answering the questions here have gone stir crazy and need hit on the head with a shovel that will leave an impression on their mind.

My friendly advice, buy a VLD tool like below and your case mouths will not be on the "cutting edge".

P.S. Never insult CatShooter and remember to read the book "Revenge Of The Cat" by Claude Balls.

 

[rsmithsr]

just for the RECORD..
the only part of reloading that involves an EXPLOSIVE is the PRIMER.
GUNPOWDER is a FLAMABLE.

[ButterBean]

may I suggest that if you think shaving unequal amounts of copper off the base of a bullet, does not affect accuracy, you have a lot to learn about the word ACCURACY and rifle shooting.

you may as well shoot them but they are trash. the last thing the bullet sees when fired is the crown of the bbl. everyone knows how precise the crown should be( well maybe not everyone), but the other half of that is the last thing seen by the crown IS THE BASE OF THE BULLET, and you just screwed it up big time.
my guess is way too much neck tension, and way too little neck chamfer.
( some sort of word processing app here ?.complete word changes)

I have hacked the end of a barrel off with a hacksaw and beat it with punches an rocks and within 3 shots it cleared up and never shot over MOA so that I know in a real world situation that my weapon will work without being pretty or strapped to bench, I have also shot loads the same as the OP's on purpose just to see and they also shot the same as previous loads i had loaded and no I'm not a Benchrest shooter with any wins as this is the LRH website not Benchrest Central , and from no more than I have read from you I wouldn't care to be, Some friendly advice, show some respect to the elders here and you'll find you'll get respect back or be a MudRunner it's your choice, That will be my last word on the subject
