Am now reloading for my 45 with Remington 230 grain. brass jacketed bullet in .452 diameter. This reload works really smooth in my 1911. Rainier makes a 230 gr. copper plated bullet in .451 diameter. Will the .451 reload the same? Will I have to adjust my expander die ? Should I stick with the Remington since I know it feeds and shoots great in my pistol.
 
Either one should work the same, depending on the brand of cases you use, and your expander diameter.

Your .45 ACP dies were made for .451" jacketed bullets, which is the standard diameter for them.

.452" is standard for cast lead bullets and some brands of plated bullets.

Some brands of brass are thinner then other brands anymore though, and will not size small enough to get proper case neck tension.

You will just have to try it and see.

I used to load Remington 230 gr FMJ bullets in my 45 and they were always
.451 diameter.
 
More and more factory rounds are loaded with plated bullets. Pull a round apart and if you see lead base, they are FMJ.

Here's a picture of Remington 230 gr 45ACP RN pulled apart to show a plated bullet.

And as far as I know, the only 'brass jacketed' bullets Remington makes is the Golder Saber.

It is a two-diameter bullet smaller in front to bore ride, and larger inside the case to fit the bore.

So .452" inside the case and .451" outside might make sense with Golden Sabers.

^In the reviews on midway, someone commented that they moved to a brass jacket? also several people seemed shocked to find that their "fmj" bullets had an exposed lead base?!?!?!?! how else ya think they can squeeze the lead into the jacket? they arent plated bullets.

bds- Interesting, I havent bought a box of factory 45 (other than 20 rounds of hydrashoks) but I pick up orphaned rounds at the range, pull em and reload em. I havent ran across a plated remington 45 but every 230gr ball federal and blazer round I run across is plated... usually easy to spot when loaded, they are super shiney and may have slight dings and not the metal "grain" you see in a true fmj.
