Found that the T/C capsules for loading bullet / ball, powder and caps are extremely leak-proof to storage conditions.

Last loaded them the ML season of 2020, and left them be for the subsequence years, this past week

Use the to sight in a T/c New Englander for use and all loads gave no problems with clumping or poor reports, Quite surprised.

Had to swap the lock out do to the hammer screw broke off and the local smith didn't complete tha removal ud threaded stem until last fall.

Just a let you know situation.
