Winchester 243 varmint x 58g defect

[Tf223]

Question - what would you do….

I have bought 100x of the above cheapo foxing rounds. On firing the first box I found a couple of rounds which visually have a longer neck and same overall lengths. The bolt couldn’t close on them.
Anyway across the 100x there appears to be 6 of these duff rounds.
The others are bob on accuracy wise in my rifle - and importantly for me they’re cheap

it’s not worth the petrol for 6 rounds if the others are fine, although the shop asked for an update and was happy to exchange the lot if I wanted.

What would you do, pull them apart and use the good ones - or take them back which barely seems worth the effort?

Thanks tf223

I would think, if they had a longer neck but the same OA length that the bolt should close?
I’m probably wrong.

i would have thought the same, but I’m no reloader. To me they look the same OAL just with a long neck, and the bullet seated deeper - and only on those doesn’t the bolt close (tikka t3)

On my T3 lite the bolt lost interest in closing on 50% of PPU carts I tried in it.
That the spec of the PPU though.

Just looking at your pictures and the cart on the right looks to have a longer OA length than the others, unless it’s how the pic is taken.

Could it be a carbon ring in the chamber and the longer necks are hitting it?

Just pull the bullets on the 6 rounds and crush them. Tip out the powder and burn it in the garden. Drop some water or oil in the case on the primer, crush the necks on the cases and chuck them.

If the OA lengths are the same, long or short neck wouldn’t make a difference.

It may still make a difference and could be dangerous.

Excessive COAL will cause a problem as the bullet will contact the leade before the head is sufficiently in battery for the bolt to close.

A case exceeding maximum permissible length will cause the neck to butt against the step between the neck portion of the chamber and the freebore, where the chamber steps down from being slightly larger than the outside of the neck to around bullet diameter.

That’ll probably mean the bolt won’t close as, again, the head can’t get fully into the chamber for the bolt to close. What can also happen though is that the step between the neck portion of the chamber and the freebore acts as a crimp, folding the case neck into the bullet. If that happens, it can cause excessive pressure as, on firing, the case neck can’t ‘un-crimp’ as it’s fouled against the freebore.

If they chamber easily, I wouldn’t worry as that would suggest they’re within spec for length (and the others are short). If the bolt is hard to close, I wouldn’t want to risk that these are dangerously over length, so would dispose of them.

I beg to differ Sir. If the neck is overly long then the neck of the case and the bullet could be jammed in the leed resulting in dangerously high pressures.
It looks like these cases have missed part of the trimming process in manufacture.
Just out of interest it would be interesting to see what the two different overall case lengths are (case not cartridge length).

Being known as somewhat of a tight arse personally I would take the offending ammunition back and get it replaced, after all the buyer did pay for 100 rounds and just 94.

I originally thought he’d said the cases were the same length but looking at the pics it’s seems the case on the right is longer.
I meant, if the cases were the same length but the neck was longer it would just mean the should er was further back and that shouldn’t stop it chambering.
Agree, if he’s bothered about a couple of quid, take ‘em back.
Ken.

I would measure the case length of the "good" ones or at least a good sample. Make sure they are less than 2.045" and weigh a few with accurate scales to check nothing else it grossly different. The COAL looks the same from your pic., it shouldn't be more than 2.71"

Take the 6 dodgy rounds back next time you go there.

Thanks - this sounds like the plan.

I’ll measure those that I think are good to double check.
It does kinda look like a few missed a trim step, the neck is visually longer on them with same overall length with bullet. The ‘bad’ ones would not allow the bolt to close, the other ‘good’ ones all closed as per normal with no notable effort to close.

Or trim the neck and reload

He said he is not a reloader.

 

[Mark120555]

Then probably isn't going to be pulling bullets

 

[Bowland blades]

Is it the case isn't sized back perhaps ? If we are talking mixed brass ? pull them all and full size them body and neck . If they are new factory - send them back to the seller
just noticed your shooting 58 grain ! These wont actually jamb the lands ( they are not long enough !) At a guess ? The brass is well out of spec , if they are used i think they have just been neck sized yet the shoulder has come further on firings. Simply resize fully !

His post is suggesting it is factory ammo and pic appears to show a longer neck. The worst thing he could do is force chamber and crimp the neck onto the bullet.
He said he is not a reloader so the safest option is to pull the bullets with a simple kinetic hammer and discard/crush the components.

If they are over the maximum case length then they will, which is why we trim brass.
