What sort of ammo?
Some bullet designs will hit the rifling sooner than others. A 147 gr round may hit the rifling before being fully seated, whereas a 115 will likely drop right in w/ no drama. When you pull the round out are there rifling marks on the bullet? Not sure? Mark it with a sharpie or similar and try again. If yes, try a different ammo design and see if that fixes it.
Rounds should drop unassisted, fully into the barrel (Google "Plunk Test") If it doesn't then there is a problem with either the ammo or the barrel.
If, after your ammo passes the "plunk test," the pistol still doesn't want to go into battery without a fight, a call to Springfield is probably in order.
