Thing is, if you can push it into battery, that sounds more like a gun issue; your ammo may be just barely within tolerance, and your chamber could have some buildup. I think it's Wilson Combat that makes a slightly oversize brush especially for the .45ACP chamber, but I don't know of anyone making one for the 9mm. I don't have my 9mm handy to measure the chamber, but the case specs show .380 at the mouth and .391 at the base, so if you can find a nylon .40 brush, it might work; you want to be able to get it in to the full depth of the chamber with solvent and twist to get any buildup loosened, let it sit for a minute and give it a couple more twists, then wet patch and proceed with normal cleaning. Use a good rod, though, as you might end up having to shove the oversize brush all the way out the muzzle if it refuses to come back out the breech, and that can take a lot of force to accomplish. For that matter a brand new 9mm brush might do the job; metal brushes tend to approach bore diameter with use, but a new one is probably oversized enough to clean the chamber, and of course, you can never have too many extra brushes for the .35x calibers.

The other possibility is that your recoil spring is getting marginal; as with the chamber buildup, good factory ammo is likely to be in the middle of the tolerance range for both size and power, (or more likely, a bit on the small side of the size range) while your reloads may be anywhere within the range. Wolff springs, if they make them for your gun, are cheap enough to buy them as a test. (1911 spring kits are under $20 for one of every spring in the gun.)

What caliber, and what dies are you using?

For pistol ammo, some calibers are very tolerant of overexpanding (.45ACP can pretty much look like a trumpet and still be fine) and others are less so. Of course, a seater that will also taper crimp should knock the flare back where it needs to be if you have to expand more for certain bullets.

Of course, for bottleneck cartridges, not getting a full stroke on the sizer will leave you swearing as you're pulling bullets after an aborted range trip.
