Interesting Lyman/Ideal 310 tool factoids.
If you have a 310 tool and dies for 30-40 Krag, you can also load .308 Winchester and 303 British.
If you have a 310 tool for 45 ACP, you can load 45 Colt. The handles, decaping die and neck expanding dies work for 45 Colt, but not the sizer and bullet seater.
If you have a 310 tool for 30-06, you can use the handles to load any and all rounds based on the 30-06 case head, i.e. 308, 270, 35 Whelen, 8 mm Mauser, 7mm mauser etc. etc. The same decaping die will work for all of these, but the other dies won't.
