- Thread starter Acadianss
- Start date
mabye its more popular out east I never see much out here and at .50cents a round if i paid 25$ for a 48 round box thats dirt cheap Prvi .303 ammo at 20$ plus tax for 20 is the cheapest i can find, Mk7z .303 at 25$ for 48 i would buy a ton of it and shoot it, the 7z is awesome ammo......if you wanna sell some for 25$ a box let me know and i'l buy a bunch
Remember, there is a HUGE difference between the DI and the DA.
DA was Dominion Arsenals, the Government plant. They made .303 ammo to British specifications, including that mercuric-corrosive Berdan primer and Cordite charge, from back at the end of the 19th Century, through to the end of the .303 period. They only changed to standard-sized Boxer primers and NCNM priming about 1955.
DI was Defence Industries, a Crown Corporation plant which operated only from late 1941 through to 1945. They got their primers from the Dominion Cartridge Company, which means that they were using standard .210" Boxer NCNM primers for their entire production. They loaded with a Nobel-type powder which was very similar to what we now call IMR-4895. Their bullets were cupronickel-jacketed for the early production, copper-clad mild-steel for later production and were held to very tight tolerances. The Brass was held to the tightest possible tolerances and rims were all either .063" or so close to it that a decent mike has trouble telling the difference: the proper military Max rim. Rim-edges were bevelled properly, too, something which Partizan doesn't bother doing. In all, it likely was the FINEST military .303" ammunition ever produced. Properly stored, it still is accurate today. And the Brass is the BEST reloading brass ever made, alhough it is getting a bit long in the tooth; a quick anneal brings it back to tops.
I count myself very fortunate; I have more than 1000 rounds of DI brass tucked away. Perhaps others should think about the same.

Acadian; from what Smellie has offered up, even if it isn't now it soon will be. Good buy if your happy.
i don't reload but from what ive read the old brass needs to be annealed, i know yours were unfired mabye it has to do with how they were stored? i'm sure a expert will comment here eventually, i found this video

Thanks for the vid OP. Here's a lesson for Internet info though...The guy in the video isn't annealing that brass, he's tempering it. This in effect actually makes the brass harder.
To anneal a metal material one must use a high carbon flame (which is an inefficient one) Acetylene flame is perfect with tonnes of black soot by product (carbon). As the metal expands with heat, carbon molecules are introduced into the metal, softening its temper.
Propane is way too hot and as you can see almost no carbon left after combustion.
In short...don't do this to your boolits

plinker 777 Your welcome for the vid OP, Read the first couple paragraphs and it explains exactly what green is talking about

Thanks Acadian. It would appear I am incorrect. ( that's twice today, and since I'm only ever wrong once a day, it would appear I'll have a fantastic tomorrow)
)Don't let it bother you, Plinker; we're all wrong SOME time.
I was wrong once, too.
I think that was back about 1956 or '57.
Just one of those things you have to grit your teeth (if you have any), smile bravely and attempt to continue.
You'll survive it, I am sure! LOL!

I'm having a much better "today", thanks all . and another thanks to Green and Acadian for setting me straight. BTW, I'm never bothered with being wrong (getting used to it actually) as long as something is learned...which in this case it was. Thanks again.
Ahh, so it's Jan (AKA Twosteam) that keeps you in line Smellie...good on ya!
