I have done some, won a 3rd in the state games years ago at 300, not impressive unless you consider I whooped a bunch of guys with much better rifles with a Savage 99 in 243 with a 1X3.5 Scope in lightweight class.
I'm going to see if I can find the right rifle maybe this winter and shoot just the long range next year, that would be easy to do and still cook as long as no one would mind me jumping in and saying I had to be next based on cooking timing.
BTW last year it was a good thing everyone was shooting open sights, if no the mirage that had to be going on could make someone seasick, if I remember right they were having trouble spotting with optical devices.
I am at times a hunter of sod poodles of which Jerry has none, lucky for him. I plan on finding the time and making a trip next spring to do that again, it's been a while.
