Not much to offer, but I did shoot collegiately for our Naval ROTC team. Many, Many years ago. I had the scores to shoot for the university team, but didn't want to make the time commitment. At that time it was a club team and no money was available other than for travel. That said, most team personnel were ROTC of some sort and were already on scholarship for that.
The national guard in SD used to have a shooting sports program for HS shooters. They provided target rifles and ammunition and all we had to do was show up and shoot. We actually had a 50' smallbore range in our HS, which was shared with the local national guard unit. Don't know how that was set up but it is still the same way there many years later. We also had a rifle league similar to bowling leagues that we shot weekly during the winter.
Maybe check into similar programs in your state.
FWIW, shooting skills arent even looked at when going into ROTC or the service academies. Only thing all the above got me was 2nd high score on the KD course for our basic school company and a pat on the back! The guy that beat me was a prior enlisted sniper who had served in Beirut in the early 80's and had many "confirmed" kills. Good dude though.
