Assuming your brass is resized enough, there are at least two other things that can cause or contribute to this.

Insufficient case belling prior to seating bullet. A little lead or lube gets smeared around the case mouth and the rounds don't want to seat in the chamber.

Insufficient taper crimp. I use a Hornady TC die myself but don't be afraid to bring the case mouth right into the side of a lead bullet. Just make sure you don't bury it there or both accuracy and headspace may suffer.

Hope this helps.

PS- Check your OAL, too. If your individual barrel has a shallow leade (into the rifling) you may have to seat a tad deeper to accommodate it. Just make sure you don't seat the bullets deeper than specified for a given powder charge. Reduce your charge when seating deeper than specified by the manuals.
