FL sizing help needed

[Triffid]

I'd say that the die was faulty.
I had the same issue with a Forster 300PRC F/L die . . . badly scratched cases and very hard re-sizing, even with Imperial wax.
I looked into the die with a borescope and found it had been very poorly finished inside, with prominent tooling marks around the circumference of the die.

Poor machining and quality control from Forster, which surprised me.
Back to supplier (Brownells), who then sent me two replacements by mistake. One was nearly as badly finished, the other merely OK, but polished UP ok with 1000 grit paper and Solvo-Autosol.

Having the borescope image to send to the supplier saved alot of argument.

Thanks it sounds like the exact same position I’m in, as I have a feeling without a borescope photo supplier may not replace. May I ask what borescope you used and I will have a look at buying one, another useful tool!

Mine was a Teslong wifi one.
They've changed the model now, but the NTG100 looks OK as long as you can use a USB connection.

Here are some pictures of the inside of my 300PRC F/L die.
You can see all the annular tooling marks and where it has scratched the brass.

Just crap lube.
Get some coconut fat and just use your fingers.
Your lube wouldn't lube a gnats nadger.

The 44 dies are probably carbide dies and don't need lubricant.

looks like you have used a neck only sizing die and you ran it harder into the shoulder ? It should be real easy to sort this but its hard to get the issue from the damage . There really is no need for neck only sizing and you will have to full length size at some time anyhow on bottle neck cartridges !
Just my best bet from the picture

Beeswax, beef fat, coconut fat, olive oil and aniseed oil.
All sorts for my muzzleloaders but it's also a fantastic sizing lube.
Never a stuck case and kind to the skin.
