Bevel Base vs Flat Base

I reload bevel base 9's an am looking to purchase some bullets that have a flat base. The ones that I'm looking at are sold as flat base only. I appreciate the ease of positioning with the bevel base. I know that bullet positioning is a rather simple task, but can the flat base bullets be problematic when dropping down into the case?

Could be. May have to adjust your flare a tad just to make sure they get started right, but that's the only problem I could see.

Never had trouble myself with pistol bullets. Now, 224" .223 rds, that's a completely different story.

Lots and lots of reloaders load lots and lots of flat based bullets, so it can't be too big of a pita. You mentioned the bullet "dropping down into the case", as if from a bullet feeder? If so, I have no experience there, but for hand placing the bullet, like jwrowland said, you may need a little more flare than you have been using with boattail bullets. I flare my 9mm cases just until I can easily place a bullet straight in the case mouth and then set my combo seating/taper die so it "tapers" just enough to smooth out the flare.

I've been loading concave base bullets for my 9mm for a couple years. Both jacketed and the coated cast variety. No problems to speak of.

I load some XTP's too. They have a flat base and a really square edge. Again, they load just fine. Sure, a bevel base might make the task just the tiniest bit more convenient, but not nearly enough to stress about.

Flat bottom lead bullets require a little more flare to start them without shaving lead. Jacketed flat bottom is not a problem at all. Most bullet feeders do not play well with lead bullets due to the lube. Hi-Tech and powder coated no problem.

Beveling the case mouth helps a lot to prevent shaving lead. In fact doing so allows your seat jacketed bullets without flaring/expanding first.

As a rule, flat bottom cast bullets will be more accurate and less prone to leading than bevel base-so any real, or imagined increased degree of difficulty in seating would be worth it to me.

This is exactly why I like my concave base cast bullets I use. I dont have any scientific evidence, but I feel like they might obturate better than most bullets.
