That flat nosed bullet used for the 218 BEE is not very accurate. Mine likes the 45 grain Hornet bullet best with 10-5 grains of IMR-4227.
I had some 218 Brass on back-order at Midway, and after months of waiting, Midway cancelled the order. Someone else may have it but don't bet on it. The only way to get brass may be to buy loaded ammo.
