Just picked up some components today from reloading solutions, cost of my ammo at todays prices is
.223 50 gn nosler ballistic tip, 27gn H4895, CCI primer = 40p
22-250 55gn nosler ballistic tip, 35gn H4895, CCI primer = 44p
.243 70gn ballistic tip, 39gn H4895, CCI primer = 55p
.308 125 gn ballistic tip, 49gn H4895, CCI primer = 73p
I havenít counted the brass cost (add 20p per round for premium brass used 5 times) and the .243 round would have been 5p cheaper each if Iíd bought a box of 250.
