You can shoot with any eligible person on Schofield if they sponsor you. I considered applying but got the same reply as you. I do have a friend that shoots there. He said they heavily increased the restrictions recently. I do not know the caliber restrictions. ---- I also heard that KMCAS has a periodic open style shoot. Any info on that?
Recoil management is a big factor in PRS as you are your own spotter. Being able to follow through and spot your impacts is crucial. In Hawaii we don't have the luxury of owning a supressor so we would have to go with a brake. I like a lot of the 6mm catridges and the 6.5X47. Not looking to build one unless access for me changes. Outer island guys are hiking into the hunting areas to shoot/practice long range. I may have to do the same as well to get pratice time. I do have shooting friends and family in WA and AZ that I may go shoot with in the future.
