+ 1 for Norma Ammo. I reload both .243 and 6.5x55. The 6.5 has slightly larger case capacity (powder) and heavier bullets. 140gr in the 6.5 usually, 55gr in the .243 for my youngest boy to shoot, and its accurate, or 95gr for hunting. I have found 6.5x55 usually available on the shelf when all .243 where sold out.
