As mentioned, you need to size your bullets for the throats as that's the first thing they goes thru. And generally .001" over throat size is recommended. Ideally your groove should be .001" smaller than your throats, but you get what you got.
My 325TR & 625PC groove are right at .452", the same as the throats.
Either size will likely be fine, unless your throats are way off, but sometimes just trying different sizes is what's needed to see what works best for your pistol.
