If I was going to go through the trouble and expense to reload for my .243, I'd pick two bullets. The 105 BTHP and 85 TSX.
Although the 95 BT and CT are surely good ones. And there's many who swear by the 85 and 87 HPBT' for dual purpose bullets.
I'm not sure that standard 100 grain PSP's would be worth my while. But 95 and 100 partitions maybe. And I wouldn't mind finding some 115 RN's just out of curiosity.
