Wow, great posts.

Would it be helpful to make the chamber casts extra long so I can check the amount of freebore on the cast and get an idea how far out the ogive of the bullet can be seated?

So is the general concensus then that provided the O.A.L. of the 310 load isn't on the lands that it as wll as the No. 2 load can be fired in the same gun? Even if the pressure for the number 2 is higher? I obviously will shoot what it's marked for if I can clarify such but would be interested to see how the other load groups.

This information is great and I'll look for everything and hopefully be able to get some good pics. It'll be a couple of weeks till I have the ammo in hand so it will be awhile till I get more info.
