I've been thinking about for quite a while now & decided to correlate all my notes together for those that like this calibre (& others) that I reload for.
It will be my new repository so if I do further work I can easily add to this post.
I would also like to encourage other to do the same so that all reloading data is together & becomes more comprehensive as time progresses

As always the old adage these loads are safe in my rifle (Mark X Mauser), but they can be used as a reference to start those along the way rather than starting completely from scratch as I did!
When I first started reloading for this cartridge Circa 1987 there was no loading data in Australia what-so-ever at the time.

I wrote away to MULWEX Australia & received a letter from a Mr W.F. Pheasant who was the General Manager at the time.
He suggested a stating point of 63gn AR2209 to a maximum of around 70gn, using standard primers rather than magnum primers on lighter loads due to them shattering resulting in higher pressures with slow burning powder.
So thank you Mr Pheasant, your information was a very handy start to a young (then) man that had some reloading experience - but nothing like this!

A lot of water has passed under the bridge since then & best educated guesses have now been replaced with programmes like "Quick Load" to give us much more insight as to how to progress & what powders to best use etc.
These however must only be a guide & as all rifles are different; so what works best in mine may not in yours!
My aim has been to try to achieve factory specification, but my main emphasis fore mostly was to get the best accuracy in that process.

Those marked with a '*' were the best preforming in my rifle with deviations of 10fps or less.
For those that are interested in the Woodleigh Hydros, I have done some testing on the Mk1's, but sadly I must confess due to feeding issues I didn't keep notes on these!
To this point I haven't used the Mk II's which have the protective tip & hence have eliminated any feed issues.

Wishing all the best to those who would like to shoot this unusual calibre, I hope this brings more life back into this wonderful old cartridge!
Jack Lott was very impressed with this cartridge, even rating it better than the .375H&H!
