Hi, Yep if your target shooting the law (And most competitions) demand non expanding ammo so FMJ is the one to use, If you get a variation to use expanding ammo (I'm sure you will if you have a 243 and are on this site) then you can use that ammo to Zero your rifle at most ranges but not for competition use. I cant answer for the North East but if you want some good FMJ loaded ammo opposed to loading your own then search out Norma 80gr FMJ's. I have used them and got sub 1/2" at 100 from my SSG-59 P1 with a 1 in 10" twist. Everyone's rifle is different but they would be worth a look.
