OverkillThoughts about the .600 Overkill
Robgunbuilder!
If I remeber right the .600 OK-1 is a .585 Nyati case opened to cailber .620??? And the .600 OK-2 is from the 3,2 inch .585 Nyati case??? Is there a .600 OK-3?
Do I remeber wrong?
And how much powder will the .600 OK full length case take as a MAX load?
Thanks!

RobgunbuilderOverkill the best way to think of the 600 OK-1 is a 600 NE with a belt instead of a rim. There are other dimensional differences, but in general thats it! The water capacity is 210 grs. The OK-2 is 3.2 inches long and the OK-3 is 3.3 inches long. I have some cases for both but have not measured the water capacity. This was done with thick walled Lathe turned brass. Drawn brass will have more water capacity.-Rob

OverkillIn that way..
And the .600 OK-3 most have a Montana PH Action or what it was?
Are you going to build a .600 OK-3 in the future?
Thanks!

RobgunbuilderA granite Mountain action is probably the best action for any 600 OK. When I get a Montanna 1999 I'll see if it works.-Rob
