I completely agree. However forums are all the same and it always disappoints me when people who clearly know what they’re talking about, who can really help people, who probably joined to help people, but feel the need to belittle and condescend people asking what might be to them, silly questions, but to newbies are just what they have been told or what they think is correct.

There are forums where I am the expert and read a question and think ‘that’s silly’ or ‘that is soooooo wrong’, and yet I’m able to respond in a decent way to not make them feel like an idiot for asking in the first place.

Don't be offended by any comments you receive regarding your questions. Some people can be a bit nit-picky regarding terminology, but on the whole you will find all the members to be friendly and helpful. Now I'm just out to try and get some head.....
I hope so too. That attitude is very common on these forums. The ‘I know and so should you’ attitude is unfortunately rife. Why not just say “FYI this is called this and that is called that” instead of sarcastic pointless comments. Thankfully 1066 answered my actual question without picking up on the nitty gritty.

It’s not that I have a “cannot be told” attitude. I certainly can. And I even opened up with saying I know very little about all of this. It’s more your pointless roundabout way of trying to belittle me with comments such as “why would you take the head off the case”. You clearly knew I didn’t know what you were getting at. You clearly knew what I was actually talking about. So why the beating around the bush to be awkward? Now the whole thread I started for advice on size tolerances has been hijacked with this nonsense because you wanted to be funny with someone on their first ever post. People like you make people like me not want to ask questions on these forums, as per the person further down saying they’re reluctant to ask questions now.

Hello, and welcome.

The best place for info about dimensions and tolerances is the body that maintains the specifications:
https://saami.org/technical-information ... -drawings/

The length you mention has an often misunderstood tolerance, firstly because it’s a '-' tolerance (rather than the more common '+/-' type) and secondly because the nominal 'trim-to' length is often misinterpreted as the minimum (when in fact, 'trim-to' is a fairly arbitrary value halfway between the minimum and maximum). It is also an important dimension from a safety perspective; if the length of the case neck exceeds the length of the chamber neck the case mouth can be forced closed, effectively crimping the bullet which can potentially increase pressure to dangerous levels.

Thank you for a practical and informative reply.

I haven’t got round to reading the entire front sections of the Lymans book as only got the whole lot on Wednesday. I presume all the info I need to know is in that?

I just got worried when my cases came up considerably (albeit to a few hundreds of an inch) to what was in the book. I thought they would have been longer if anything from stretching.

It doesn't help when suppliers like Kranks among others call the bullets "heads".

I think it stems from many calling the ammunition 'bullets', so if they wanted the bullets they'd have to ask for the heads or think they might get complete ammunition.

But then we can all call them 'pills' like I see them referred to in one or two UK shooting magazines and stop all this nonsense.

It doesn't surprise me rugersteve that you have chosen to see things that way, however wrong that is.

I make no apologies for taking the responsibility of reloading with some gravitas.

You are the one who asked if we were "serious" about correct nomenclature and when it was pointed out to you that we were and how important it is along with a less cavalier attitude to sound reloading practice you chose to be offended.

Taking time to read and absorb the how to parts of the Lyman manual will help you greatly and enable you to come back with more informed questions.

Several people have commented on your response, it wasn’t just me. It’s ok, there’s people that make replies like you on all forums. I’m not offended. I’m thankful that some did offer their help on my actual question. You have a great day.
