That is your prerogative. OTOH, you can also get a die that is too loose. And some of your brass won't hold a jacketed bullet with full neck tension. Sizing dies seem to come in a range of what is considered acceptable.
I personally rather have a die that is a little tight and to fix it with expanders for my specific bullets rather than too loose. But if you are lucky, you can get one that is just exactly right for you and your bullets. I don't own a die that meets that description. The variation in brass, and variation in what I shoot (both jacketed and cast), makes that perfect die somewhat of a unicorn.
If a die is exactly sized to make, say, thin R-P brass just the right size for a jacketed bullet, then you can still come across a thinner piece of brass, here and there, and if you're not paying attention you can have a setback high pressure event. Your thicker brass will still be slightly tight for seating a bullet. IAnd if you're particular about your shooting, you will still want an oversize expander for larger, softer plated and cast bullets.
If, OTOH, you use an expander to make the brass exactly the right size for a bullet, it will work in all brass, as long as the sizing die is tight enough. Notice the expander is working directly on the interior diameter of the case, which is what is important. The sizing die is working on the outer diameter of the case, which means the ID will vary between cases.
So for a size die, somewhat undersize is actually perfect. Consider bushing neck sizing for rifle brass. Depending on the brass, you need to use a different bushing to get the ID where you want it. Trying to use the sizing die to get perfect neck size of a pistol case is a little bit of a fools errand (even though this is often what is happening in many die sets). The rifle guys using these kinds of dies are using matched headstamps and/or turned case necks. Not so many people do that with their pistol brass. This is why we have expanders and not just one universal flare die for all our ammo.
But all that said, I do think that 468 OD of your sized base is needlessly small by at least a mil. If you want to shoot only one kind of bullet, you might want to roll the dice and try another. If you want to really be nit picky and shoot the most accurate ammo you can, you will end up using custom expanders for your soft/oversize bullets, anyway. Having a tight die ensures that you can carefully control the ID of your cases with expanders, at the expense of an additional one-time, upfront investment of time and money and effort.
It might be a good idea to pull some rounds and measure the base with calipers.
This is one of the litmus tests to see if your sizing die is too tight for your bullet (or expander too small, if that's the way you want to look at it; but note that all factory pistol expanders are too small for plated bullets, by default). Be sure to measure all the way around the base. A tight case isn't the same as a bullet sizer. The bullet might measure the same diameter all the way around, except for a flat spot that is undersize. Pull the bullets from your thickest cases to check for this kind of damage.
