I need to know what size drill bit I should use to make a friend a loading block for .243 and a .270. I used a 1/2" for my 30-30 and .308, and it worked fine. Is 1/2" a good size for for .243, and .270? I don't reload those those calibers so I don't have a case to use as an example. Aren't .243, .270, and .308 all based off the 30-06 (just necked down and shortened for the .308)?
