That I am aware of, they have short lanes that you could do that with. 150yrds max. The long range platforms I’m not sure. I do know that they went to members only this past fall and Glenn Stilson would be the guy you need to speak with. Runs the Range and I believe I paid $250 for a 6 month membership. All there info should be on line at Cowtownrange.com
They do, indeed, have monthly long range matches at CowTown. Next one is April 14th. I'll be spectating (still shuffling gear and settling my rifle ADD, haha), but know a number of people who go, and they're all good people!
AZLRPRS will have a monthly match on the 2nd Saturday of the month through the end of the year. Match fee goes up to $40 starting in June. Info on those matches is posted on SH under the precision rifle club section, on Facebook under AZ Long Range PRS, on Practiscore, and on the Precision Rifle Series club series.
