If the brass you'll be using is new it
shouldn't need to be resized to get a good grip on the bullet. But do follow Hawkmoon's advise on using the wood dowel to prevent bullet setback.
Whether or not you'll need to flare the case mouths before seating the bullets depends on whether or not the corner of the base of the bullet is rounded and whether the bullet really has a thick jacket or is simply plated. If you can see lead in the central part of the base, it's a jacketed bullet (except for the Hornady 45177 which is a jacketed bullet with a copper cap on the bottom). If you chamfer the insides of the case mouths of the new unflared cases you may possibly be able to seat the bullets if
extreme care is used to prevent the bullet from tipping. If the bullet tips it will crinkle the case mouth and ruin the case.
But if your bullet jackets have sharp bottom corners, you'll no doubt need to flare or enlarge the case mouths to accept them without crinkling during seating. Enlarging can be done without normal reloading dies by using a #8, 2½" long taper pin. Enlarge just enough to allow the bullet to sit on the case mouth without tipping and they may seat OK.
In addition, with the bare minimum of case mouth flare (enlargement) seating the bullet may expand the rest of the case and eliminate the need for any "crimping". Use a single edge razor blade as (maybe) seen below to see if seating got rid of the flare.
