I'll confirm what Aussie Jumper sais.
Whinchester pwerpoints are standard fare over here, and my Anshultz loves to put them into a Coverleeaf at 55 metres. I hate solids on rabbits, was gven a brick of Remingtons and none of our familly rifle like em. I got a guage out and they only measure.223, not .224 like the Powerpoints.
I've since palmed the other round off to another mate who had used them for plinking.
Hey Aussie Jumper, what part of Melbourne, trying to hook up with any fellow Shooter in Victoria. My hunting has become limited ever since the farm I used to shoot on got taken over by some big companny that doe'snt want shooters on the property.I'm a safe shooter who was employed as a farm hand every now and then on Eildon trout farm when we owned it 5 years ago. I'm deemed to be overly saftey conscious by my mates.

It's up to you, mate
