A whole lot will depend on the powders that you have on hand… or that you can lay your hands on … for the 460 Rowland … If you go to the Loaddata website,& type in .460 Rowland … there are a number (~ 90) loads listed with the various powder types … & bullet weights…
That might tend to give you a place to start… to figure out where you want to go. Even If you are not already a subscriber to Loaddata … the basic information on the bullet weights and the powder types & Sources that have published data will still be there for you to read & ruminate on …

Thank you, I will look at load data for sure. Has anyone tried feeding the https://noebulletmolds.com/site/product-category/bullet-moulds/452-454/453-240-rf-ab4/
bullet in a 1911? Looks interesting for the 460 Rowland.
thanks

If you go to loaddata you will most probably see that any bullet that is suitable for the 45 ACP will most probably work in the .460 Rowland… as the cartridge case is by design a bit longer than the standard 45 ACP cartridge case…
In this way the .460 Rowland is like the 38 Special and the 357 magnum so that by design the .460 Rowland can not be accidentally loaded into a standard 45 ACP cartridge chamber… In regard to the cast bullet selection … you will most probably note that any bullet design recommended for the 45 ACP will work in the .460 Rowland…
Just be sure to stay within the cartridge overall length (COAL) for the .460 Rowland… In regard to GC or non GC versions … most of the loaddata I tend to belive shows a FPS speed of less than 1600 FPS… Which is basically where I switch to a GC version… design format.
So unless you really want to go the GC route … a NON GC version should work in most cases…
In the for want it is worth department … there are Aluminum litho plain base GCs out there that you can buy or make … that will allow you to GC the bottom of a plain base cast bullet turning it into a GC version… (Al litho plate is softer than the normal Cu GC) … It will be the nose shape for a .460 Rowland semi auto pistol that you will most probably want to to adhere to… as a smooth feed in a semi auto pistol … besides the load is the goal here …
Now if you have a revolver that has a second cylinder that is converted to .460 Rowland … then you can experiment with the wider meplat types such as the semi wadcutter, the wider meplat round flat mould types , and the full wadcutter … as like the 45 ACP cartridge case you will be supporting the loaded .460 Rowland cartridges with 1/2 & 1/3 cartridge case clips… in the .460 Rowland’s revolver cylinder…
I also tend to make up several dummy cartridges (No powder Nor primers) to test the feeding & smooth chambering, + going properly into battery on the .460 Rowland of those cast cartridge designs…

To specifically try to answer your question about the NOE cast bullet that you referenced… in regard to the 453-240-RF…

The wide meplat on that particular cast bullet design does for me at least … not tend to feed well loaded into in the 45 ACP cartridge case in a semi auto pistol. Since the .460 Rowland is basically a longer 45 ACP cartridge case one might also tend to see the same issue down the line with those longer loaded cartridges …
However that particular bullet does in fact tend to work rather well in the revolver applications where the loaded round is already in the cylinder chamber & becomes aligned with the barrel as the cylinder rotates into position. Each mould design tends to have its pluses and minuses … In a revolver … the wider meplat is a definite plus factor.
In the for what it is worth department … you may also need to look at the magazine followers in the competition mags … that you might potentially be utilizing … As as they are most probably setup for the lighter bullet designs which tend to need a slightly steeper angle to help center the loaded cartridge into the semi auto pistol’s chamber … So that there is somewhat less recoil, with a quicker recovery time from the lesser recoil… Your call on that detail… on whether you want to talk to the cartridge designer to see what magazines, and bullet weights that he might personally recommend. you to utilize.
Thus with the heavier bullets with a wider meplat in conjunction with the steeper followers on the competition mags may just tend to make the bullet with a wide meplat come in contact with the top edge of the pistols chamber, rather than the polished lower edge feed ramp on the semi autos…
This tends to try to cause the round to hang up rather than chambering smoothly.. For a Semi auto pistol one tends to need to look at that aspect of the cast bullet nose design also.
