I don’t know if it has anything to do with the coating or not but I’ve gotten better accuracy with coated bullets. Given I have only tried a very small sample of uncoated cast bullets, take that with a grain of salt.
I assure you they will lead the barrel if you are determined enough.
A valid accuracy test would be to compare bullets made from the same batch of lead, from the same mold, cast at the same time. Lube some with traditional lube and some with "coating". Then shoot them under the same conditions, on the same day at the same target from the same distance, over the same load, in the same cases, from the same gun - properly and thoroughly cleaned before and after.I have also gotten better accuracy with coated bullets in .357 and .45 Colt. Whether in revolver or lever rifle. The only exception was 165gr rnfp coated in 30-30. But, I ran out of bullets to keep trying. Back to jacketed for that one.

More likely a function of not being cured properly. If the instructions aren't followed correctly leading will result even with light .38 Special loads. I run coated bullets in 450 BM and .30-06 without issue.
Hay I resemble that remark.... I have colors assigned to mixes. Warm colors, oranges and reds bhn 9-10. Cool colors blues so far are bhn 12 and up.They make color-coding loads easier, too. Blue for Smurfs, Green for Zombies, Red for Dragons...
There seems to be a lot of people with the notion that you can’t push lead Bullets (especially coated)to jacked velocities. This is false.
DMW1116, by the wording of the OP, I would say that there is a good chance he was thinking handguns. It is common to find load data for both cast and jacketed in handguns. Cast bullet rifle load data is generally not available from "typical" reloading sources. Numerous responders seemed to have figured this out and also appear to be thinking handgun.
However, as you noted there is the possibility of using cast in rifles (or specialty handguns like some of mine) that allow for velocities above where cast bullets have any reasonable chance. However, this is probably irrelevant to what the OP and most responders had in mind.
I bet if one wanted to find the limit a cast Lee 55 grain in 223 would give you enough velocity for failure if one was looking.I think the original question was most likely limited to handguns. There are enough replies referencing rifle cartridges that without more context its difficult to tell what is meant later on. Can one push a 200 grain coated cast bullet from a 308 Winchester at about 2200 fps without a problem? Most likely. Can it also be done with a 135 grain coated cast bullet at 2800 fps? Probably, but I’d say it requires some special preparation and knowledge.

Are they loaded like waxed cast bullets or jacketed?
I'm guessing cast, as they don't say different, but they advertise how great the coating is, which makes me wonder if they can be pushed a bit harder...

Get the lead bullet spinning fast enough and they'll tear themselves apart. I believe the limits for good accuracy are around 120,000 to 140,000 RPMs and disintegration will happen around 200,000 RPM. It varies depending on the exact alloys used, Jacketed bullets will have the same thing happen if you push them fast enough - Think light bullets in something like 300 Weatherby Magnum.
I want to cast a 223 heavy ish bullet to shoot out of my 223. Noe has heavier molds but data gets real sparse. A 70ish at about 2k fps would be nice.That would be entertaining, once. It's not hard to get above that limit with a fast-twist 223 barrel.
