Bravo, now that is a good idea too, I love my 9.3x62and my 9.5x57 as well as my 7x57, 8x57. But is also think my 338.06,
338.08 (Federal) and .458WM are excellent too, hmmm there are more to but I am going off topic and dreaming again

My original comment stands, if you just want to cut down the number you have keep the 7x57 and the .318. They will do anything you ask of them with the loading components available now days
