minimum bullet hold?

[taliv]

what's the minimum amount of contact, in terms of fractions of an inch, that is appropriate and safe for varmint rifles?

specifically, 220 swift, 22-250, 22-06 type calibers

is .100" enough? .200"?

Are you asking how far the bullet should be inserted into the case?

Most would say at least an equal amount to the diameter of the bullet.

Depends on how the cartridge is going to be handled during loading into the chamber. On a single shot the bullet only has to be seated far enough to keep it from falling out of the case and enough so it just touches the rifiling when the action is closed. If the cartridge is going to have to withstand the rigors of feeding from a magazine and be subject to the recoil of other rounds, then it will need a better seat to keep from being upset. Stringers answer is a good rule of thumb.
