Does 0.001" matter? Obviously pressure will be higher all other things equal but surely you could work up a load with a 0.001" oversize bullet.
The reason i ask is because there is some variance in bullet sizes for certain calibres. For example:
- 44 cal can be either .430" or .429" depending on bullet maker (.4295" from sierra!)
- 45 cal (handgun) can be .451" and .452"
Another example, and the real reason i'm asking, is that Hornady make bullets for the 450/400 and their bullets are 400gr .410". They also make 300gr .411" bullets for the 405 Winchester. Woodleigh make 400gr .411".
Can the .411" bullets be used in a .410" barrel? Would i need a different expander ball/neck sizer for each bullet diameter?
I was just thinking that a 400, using the 300gr .411" for deer (up to the big ones on foreign shores) and either of the 400gr for the bigger things out there, would be one hell of a rifle to hunt the world with.
Beware the man with one gun....
