Will do Bigfella. I'll be loading up the tent and heading up to fox country later in the week. Going to range tomorrow to try out some test loads with the ADI BM1 powder from 20 gns to max at 22.5gns going up in 0.5gn increments to decide what to load. I've got some already loaded from years ago but looking at the fired primers I think they might be a tad hot. The trigger was super duper heavy so got a set of imperial allen keys from Bunnings this afternoon and they seem to have done the trick. Tiny screw in the trigger guard and a couple of counter clockwise turns appears to have lightened the trigger considerably.
I'll have some interesting gear to try out including a you beaut LED light to go on the scope, a Night Tech HD-25 thermal monocular, quad shooting sticks and an MP3 player loaded up with a call which the guy at Foxbusters kindly sent to me (played it for the missus while she was getting dinner ready and her response was "turn that f*ckng thing off" so it definitely works!). I got the MP3 player on Ebay for $30 (pictured), so I'll be keen to try this out. I've no idea if it works better than a fox whistle but it may be an advantage to be able to put the player 20 or 30 meters from where you are located. I'll let you know how it all goes!
