Can somebody give me the OAL of a 45 acp cartridge loaded with Lee's TL 452-230-2R 45 with the bullet seated to the edge of the last tumble lube groove?
Any preference between it and the Lee 452-228-1R?

Do you mean 452-228-1R ? http://www.leeprecision.com/html/catalog/bullmol2.html
Yes, that is what I meant.Do you mean 452-228-1R ?
I'm guessing that the two Lee bullets shoot just about the same.
load them till just short of the lands......al guns are diffeent
i sold my 228 because of the oal issue in two guns....when seated to feed in both guns was too short for me and too long of a jump in one gun.

only accurate rifles are interesting
http://castboolits.gunloads.com/show...ght=452-230-2R Lots of comment on Lee bullets on this thread. I dont own any Lee moulds. But i have seen where the 452-228-1R had to be seated extra deep for the round to chamber. This is caused by an oversize diameter mould making a larger then normal ogive, when trying to load & shoot it in a short chambered firearm. Sorry, this does not answer your question. A TL bullet, no sizing (you hope) the other need sizing.IMO. Here is how to set oal >![]()

A couple of comments.
First, it's not an oversize mould or lack of sizing that makes chambering the 228-1R difficult. Even sized to the proper diameter, 1.265" with this bullet is too long as the bearing surface is too far out of the case. The problem is attempting to load it to ball OAL (around 1.265" or so) when it is not a duplication of the ball bullet's longer ogive (it's a 1 radius rather than a 2 radius; 1R and 2R is indicative of this). I have to load the 228-1R to 1.220" to get it to chamber.
I load the 230-2R to 1.265" to pretty much duplicate the OAL of ball ammo. In this case the right bullet is being used for the job.
The "OK flush headspace" picture is somewhat misleading, but it is a good way to make sure the ammo will chamber, so I'm acknowledging its worth while pointing out a misapplication of terminology. On many, if not most 1911's the end of the hood is not the headspace measurement. The picture implies flush with the hood ("flush headspace") is essentially zero headspace. That's often, if not usually, not so.
It is possible to chamber a round successfully and properly even if the rim is above flush with the hood IF there's some slack between hood and breechface, as there often is in factory fitted guns. On guns with a hood to breechface gap when in battery, zero headspace would require the round to be above flush with the hood equivalent to the breech/hood gap.
The headspace measurement is the distance from the standing breech to the chamber stop shoulder when the gun's in battery.
You'll often find, except for oversized hoods, that the distance from chamber stop shoulder to the end of the hood is often considerably less than the maximum possible chamber length, precisely to allow for the gap twixt hood and breech when the gun's in battery. The depth measurement feature of your calipers will confirm this for you, as it's easy to rest this on the chamber shoulder and measure the stop shoulder to hood length.
Just FWIW. The picture would be accurate for some of my fitted, oversized hood Bar-Sto barreled 1911's with their zero hood breechface gap, but not for my factory Colts, which have a noticeable gap, as do many other brands in factory trim.
