Thread: Another Trip to the Range

Greetings @Micky Duck,
To me you are making a container of new powder into older powder. Powder does have a long shelf life if stored correctly but I prefer to keep the new and old separate. I have found some older containers of powder that has been badly stored that have deteriorated and clumped. Before ADI went to the kilo containers I usually bought two 500 gram containers each time I needed to resupply. You don't tip the dregs of an old bottle of milk into the new one so why powder?
Regards Grandpamac.

I do it with motor oil too. Have not had powder sit long enough to be considered old. Any slight batch variation will be less by blending in old.not that I will notice anyway without chronograph and only shooting sub 350.

There are two tins of IMR4831 in the garage that were given to me. Packed in 1987 and unused there was rust on the outside and inside of the cans and the powder had clumped. It will be spread under the trees. Also in my powder cabinet there is a part tin of IMR4064 packed 10 years earlier which is fine. Recent chronographing shows velocity right on the button. The 4831 was likely stored in a tin shed sitting on a dwang (nog for SI I believe) hard against the tin cladding.
GPM.

They were dwangs in 1970’s chch where i was brought up (dad was a builder ) I always thought nog was a north island term ��

Only for builders who cant spell.

Greetings,
This had me interested so I fished out my copy of NZS3604:1984 and it uses the word dwang so nogging, not to be confused with noggin, seems to have dropped out of use by then. I do remember it from specifications from the 1960's and 70's.
Another bit of useless trivia from GPM.

I think the use of noggins has also deminshed since then too

I left CHCH in 1983 for the north island and it would have after I headed north I heard them called nogs for the first time. Ran a commercial construction business 2009-14 in Wellington and am sure thats what our PM’s and SM’s called them.

Greetings,
Apparently dwang is a Scottish term used there an NZ. Nogging is used in England and Australia and blocking in the US.
Back to shooting and handloading.

Yes good point sorry for going off the reason we on here��

Hey it's all a learning process to me...been here twenty years and still learning the language and I was born in Britain

Interesting. I'm also the product of parents brought up during the depression. Lol

Smokeyjason was kind enough to give me some old powders a while back. I thoroughly tested the Noble's #2 and its burning as expected with the data I have for my 30.06. So, I decided to blend the 2 tins I had. One about 3/4 full, the other just 3 or 4 Oz. Close to a pound now.

Also, as I have a variety of brass I've collected, a few months ago i decided to weigh a few cases. (20 of these, 50 of those. etc) It's been an ongoing process with the thought of mixing similar brands. Like GPM I can't be bother doing the volume thing.
This is the result. All averages of 5 randomly selected.

I'll be mixing a few now.

Does anyone know how critical the case volume is?

Well if your close to maximum in a large case,and poke same in small case you could be in for change of undies if not worse...however if your loads are mild- midrange to begin with at worst your largest case will be mild and smallest hot but not over pressure. From my experience with a few different rifles,it MIGHT make you miss headshot on rabbit at hundy yards but probably not a body hit.

Case weight may not directly correlate to case volume. Weight variance can be due to the extractor cut in the base rather than volume differences.

Smokey Jason also gave me a small amount of IMR4831.
Must be at least 35 years old. Tested that in the 30.06 too. It's fine. I'll finish off the tin by loading the 70 or so 150gr bullets that came in the package.

If it looks OK, smells OK, little or no rust, it'll generally be ok.
