Neck tension - bullet puller - accuracy question??

[shanesymyrozum]

Was out at the range enjoying a beautiful afternoon doing some load development. Found two real winners In any event, I had loaded up five different seating depths for each load. My question is, if I give the leftovers a couple of whacks in the bullet puller, and then seat them to what I've found to be the optimal depth, will there be a change in neck tension, which will in turn affect accuracy?

They'll work just fine.
I have done what you describe on many occasions.
Only difference is I use a Collet puller to pull the bullets out a bit.

Yep me too I use the kinetic hammer to tweak them out a tad and just reseat to best depth. Just moving the bullet in the neck does not seem to affect neck tension like pulling completely and reseating does. I suspect the stretching happens on the seating cycle further reducing neck tension.

Eagleye, I use the collet as well but dont have correct collets for all cals, it seems to work identical.

Collet size

Don't need collets of every size, if you'r close say one caliber out you can use a shim brass or aluminum of .010 inside the collet.
