    I know a lot but it seems less every day...

    Due to the exorbitant cost of reloading components, warning shots will not be given.

    NZ made (Colonial Ammuniton Company) MK VI rounds loaded with cordite. Standard issue until replaced with the MkVII round. Roughly pre/early WWI era.

    Google "Mkvi .303" will give you more detailed info on the round.

    Found a few of the projectiles, as well as the MK VII projectiles at the back of the farm which was used as part of a WWI training camp.

    I do remember as a teen firing a ton of those heavy round nosed rounds out of dads' 'Three Oh'. Had phenomenal penetration through native timber. I for one would not be hiding behind a foot diameter tree from someone intending to do you harm with those. Straight through and most of the way through the next tree

    Must have been effective, as there are no elephants left in the wild here anymore.

    Shhh, copyright infringement ha ha.
    Yeah, I have all the books you can on CAC. Cost me a small fortune.
    Barry is still alive I presume? I visited his workshop long long time ago back in my black powder days.

    The bullets are still good, and I have a number of them. So will probably pull them and reuse. Anyone got a good load they like?

    Ken Waters Pet Load for a 215gn Woodleigh was 46gn of RL19 - very accurate apparently.

    Another forum guy gave me his load for the same bullet as 43.5 gn of 2209 doing 3100fps out of a Ruger No. 1. He told me "It had a fairly short barrel as the previous owner had put a suppressor on it. It is about mid range load on the ADI handloaders guide. I tried it at 300m with a 100m zero to see what it was like at longer ranges and I managed to get about 1.5 inch 3 shot group...albeit nearly 32 inches low at 300. ES on the speeds was from 2056-2083 FPS averaged 2072 FPS across 5 shots."

    Have just reloaded some 1917 dated CAC brass. After tumbling annealing and sizing it’s like brand new. ��
