I would guess a 300PRC which is a 375 Ruger necked down. Something I would like to do for 1000yd BR.

300 "shobby" is something John shobbrook and Jerome came up with. It's a 375 ruger with the shoulder pushed back and blown out so you end up with more neck length than a WM or Dakota and still plenty of capacity to push 230s. Ticks a lot of boxes :-)

I like the 300 skadi which is the 300 Norma with the same treatment but moves back to the "short and fat is where it's at" design. I haven't seen any around in the flesh but again it may be because of the lap boltface requirement.

I am setting up a 300wsm for 230 berger OTMs as this is pretty much the energy limit in NSW F open. I expect to get around 2800 fps tops and i hope that will be enough.... Its a 9 twist bartlein HV barrel.

...yes i see what you mean about the prs, its based on the case on the left. My 300wsm230berg load on right ....

So the 6.5 PRC looks to be a bit of a barrel burner. Not that that should worry Frank too much.

Impressive! Too much energy for Qld ranges though...

RDavies, My guess it will be if you run it to it's potential. I did it to try and see what happens as well as it uses the same bolt face. I guess I could've done a 7WSM type case as well.

My original starting load (as there is no load data) gave me 2800fps and accuracy was excellent. Then I bumped it up two different loads and went to 2850 and then 2900 and again accuracy was still excellent. So now I bumped the load again and I'll see what it does.

So theoretically at 2800fps I would make the range limits for Aust. and could come down to visit you guys? :D

You would only need to run it slow in a few states, not all have the very low energy limits.

Hmm, just over 4000 ft lbs of energy, won't make the energy limits in some states. I just make it in all states with my old fashioned 30/06 AI with 185 VLD bullets. :) :) :) :)

Thats OK Keith, I dont want to shoot it in all states, I wont take it to Belmont or Bendigo. I want to try it at the match rifle ranges in NSW and they told me wsm is ok, but not winmag. I have a 7saum for my barnard for the other stuff...
