Thread: 243 Powder an Projectiles

I know some of this has been covered on here half a decade ago. Starting to load for 243. AR2209 is out of stock everywhere.
Should I start with Winchester 760 or AR2206H?
Thinking to try Hornady SST 95gr, Speer BTSP 100gr or whatever else..seems much of a muchness at this point.

18” barrel with suppressor
1-10 twist
Shooting 200m Max more like 20-100m.

Any recommendations?
