Quoted: Sealants are used to waterproof the finished ctg, NOT to prevent bullet/primer movement. Witness the crimped necks and crimped primers of Mil-spec ctgs. As noted above, your issue lies elsewhere. |
Actually, the brown goo they use to seal the neck increases bullet pull substantially. Just try to pull one of those bullets. You'll be smacking that hammer for hours or your collet will mangle the bullet in the process. Unsealed bullets come out with ease. |
As noted, the stuff is a form of liquid asphalt. With age, it does stiffen up and increase difficulty of pulling the bullet. However, that is more-or-less an unintended consequence. If the sealer alone was sufficient, the mil would not go to the expense of crimping.
If you have an asphalt-sealed, uncrimped bullet that you want to remove, just set up your press so the bullet-seating die just nudges the bullet inwards a little bit. This will break the seal of the asphalt, and allow the bullet to be removed MUCH more easily. If you're using a collet-type puller, this trick will reduce the collet-induced marks on the bullet. If using an impact (inertia)-type, this procedure makes smacking the bullet out possible, period.
Side note on inertia-type pullers--the hammer style: always smack them on the END grain of a piece of 4+4 lumber. Doing so greatly lessens the chance of the thing shattering and possibly injuring the user. Also, but a little bit of foam in the receptacle where the bullet will impact once it comes loose. This lessens the chance of the bullet being damaged, expecially soft lead and hollow-point types.
As for crimped, sealed bullets, it is probably best to just use a good collet-type puller, and adjust for minimal bullet damage.
