Going to start loading 45acp for the first time, so I was looking at adding some 200 grain plinker .452" bullets from MBC to my order. I was looking at a few different 200 grain RNFP's and noticed that there was about .050" difference between the two bullets that I was looking at. Is this something that I should look into more, or just pick one. Both bullets have a crimp groove and are coated. Thanks.

I assume you are asking about bullet length? I don't see an issue.
I'd be more concerned with bullet hardness to match your proposed loads.

Yes, I was noting the difference in bullet length. As for hardness, all of the 200 grainers are 18 bhn.

Those sound like bullets intended for a revolver. You don't need or really want a crimp groove for a semiauto bullet, as the case mouth headspaces the cartridge and seating it into a groove hides the lip or rounds it over, which effectively shortens the cartridge enough you might have ignition problems. I'd also wonder how the round nose might feed.
Now, if you're loading these for a revolver like a M25 or a 1917, in the noted words of Rosanne Rosanna Danna, "Never Mind".

That's a good point. I was thinking about shooting them in a 1911 as well as my 625's.Those sound like bullets intended for a revolver.

I load a 200/205 RNFP in 45 ACP, it has a cannelure for crimping just don't roll crimp! I shoot the same ammo in my 625, M1917 Brazilian Contract, several 1911's, three Sig 220's and a Marlin Camp 45 carbine. Not one issue in any gun ever! For logistics' sake I use the same bullet, primer and powder in 45 Colt too.
Load up about 2 magazine's worth, and test them. If the work in an automatic, they'll work.

Thinking that either one of these would be good to start off with:

Neither of those bullets has a crimp groove. That's a lubricating groove, but no lubricant is needed because they're coated. The small difference in length is because one bullet is round nose and the other is flat nose. Both bullets are excellent choices for .45 ACP and as noted a taper crimp is required.

Yeah, those should be fine for either semiauto or revolver. There's no crimp cannelure and the profile of them is very much like a FMJ (ball) bullet. I've not used coated bullets but try a few without a crimp and see if you get any setback in the cylinder or magazine from recoil. I'd use a light taper crimp if you need a crimp, it will make the rounds suitable for semi or wheelgun. I only load .45ACP for a 1911, I shoot .45 Colt in a revolver.
When you seat them make sure the seating depth is the same with both the RN and RNFP. You'll get a slightly longer OAL for the round nose, but if you seat them to the same OAL, the round nose will sit deeper in the case, changing your pressures (higher) if you're using the same load data.
