From everything I have heard about the Crockett Rifle, they are a sweet shooting gun. I have no personal experience with the .32 caliber yet. I do intend to get a IBS barrel in that caliber or .40 caiber for small game. I just have not decided yet. The one thing I read over and over on posts about the small caliber rifles (funny we should call a .32 caliber small when many modern rifles are less then that, and are standard hunting fare.) are they fowl the barrel fast, so swabbing is a necessity.

I am sure your rifle will come with a manual where different loads will be suggested. As for loading it down for starlings and such, well you can only try and see what happens. As any of us who have forgot to put powder first before the ball, and had to pack a nipple hole or bolster clean out hole to get enough powder to expell the projectile, very little powder is need to make that ball fly even 35 yards with enough power to bounce back about 15 feet (personal experience talking here... )

Good luck with your new rifle and keep us posted as to how well it shoots....
