best resource for 230 gr 45 ACP data

[BMartin1776]

curious what is the best resource for reloading data on 230gr copper plate, round nose in 45? I have IMR SR4756 smokeless powder

Main reason I ask is I was watching a video (2008) on reloading and guy had a manual out (looked like Lyman) with data showing OAL at 1.275 but when I looked on Hodgdon yesterday it said 1.2 and while I was out I saw a reloading book saying 1.2... so how many sources should you refer to for recipes and how do you pick the right/ safest one for the powder your using? Granted the recipe from the manual in the video is old but it is the same powder grain etc

Yes I took a class on reloading but this didnt come up if I recall...

The data on the Hodgdon/Win/IMR site would be what I would use. I use Titegroup, and just go with the published loading data.

Fwiw:
200 & 230 RN
Easy way of remembering .45ACP "general" RN OAL
1.23" = .45
1. 2 3, .4 5

Loaddata.com has a lot of date also for general information there is alway Wikipedia.

As for .45 ACP OAL

OAL depends a lot on the bullet you are using. If you measure a lot of different brands of bullets you will find they are different lengths from the base to the tip.

Things to remember the bullets must fit in all the magazines you plan to us them in. You don't want to seat the bullet so deep that the start of the ogive is pushed into the case causing an edge on the top of the case that can hang up and cause a jam. You also need to make sure the round cambers correctly.

Who taught this so-called class?

Right off the top of my head I will say to get Modern Reloading with Richard Lee 2nd Edition. AKA The Book of Lee, AKA BoLee.

Lee gathers data from the manufacturers and then publishes it in their book. Then, after you have that boLee, go and download the data from the Hodgdon/IMR site and compare.

If you do not see any under Lee for PLATED 230gr with THAT powder (and you will not) then look for CAST LEAD data and if not there, then look for Jacketed bullets at the same weight...

General Rule of Thumb, BoLee is the best when it comes to data. They list the BEST powder FIRST, so if there are 25 selections and yours is number 22, it certainly AINT the best choice. but if it is number 10 or less from the top then it is a better choice on the list...

MOST of the time the OAL listed is the MINIMUM OAL, so you should NOT go shorter than that. Doing so would cause a larger pressure spike. SO you can load LONGER or as short- UP TO that number specified. MOST folks load their .45 acp to anywhere from 1.215-1.260 all depends on your guns. Load for 1.249 and you get good 1911 ammo...

Nobody gives a damn about how long you make your bullet it seems. The limiting factor is fitting into a mag so you aint gonna be making 2" long .45 acp loads and if you did then pressure would be so nill that you would be safe by a mile. (yes, I am slightly exaggerating here).

Anyways...

Lee book sucks. I don't understand why anyone reccomends it.

OP, I have used IMR SR4756 "smokeless" powder in 45ACP and found it to be quite smokey. I tried the same powder in 40S&W and it was still smokey but not as bad. Not sure if that is due to higher pressures of 40S&W. My powder charge was about 1/2 way between min and max from the Lyman manual (don't have those numbers handy).
I then tried Titegroup in 40S&W with same bullet and primer and it was very clean. Maybe SR4756 is inherently smokey? I would be interested to hear how it works for you.

Cause it is the goddamn Betty Crocker Cookbook of load books. It contains so much load data in it that it made my Google Nexus 1 lb heavier JUST BY DOWNLOADING it...

What do others have? eh, they got a few loads, but the Bolee has them all...



Yes that WAS an exaggeration...

[BMartin1776]

is it correct though that the lower seating at 1.20 is a result of the amount of "punch" the powder has? If it is seated higher 1.23-.25 does one risk malfunction?

Whatever source you use for load data, you may want to verify if the measurements are minimum or maximum.
I have the Lyman 49th Edition and their OAL are maximums. In the "Introduction to Data" section just before all the load data they state:
Catridge Drawing (shows dimensions)
"This information is based on the maximum allowable loaded cartridge dimensions according to accepted industry standards. With the exception of bullet diameters, it is unlikely that the reloader will ever encounter a cartridge with these dimensions unless a problem is present. The listed dimensions, when compared with the reloader's ammo dimensions can be a help in making certain maximum dimensions are not exceeded. For example, if your loaded cartridges have a neck diameter equal to or greater than the listed dimension for your cartridge the ammo should not be fired."

Where did you take your reloading class? Determining the proper OAL is kind of a big deal. I would want my money back.

Most bullet manufacturers will give you load data on their site or if you email/call them. It is mostly a starting point since all guns are different.

The load he was working up may have been for a different powder. This is what is recommend for your powder:

It has info just like all the other books. I use in along with 4 other manuals as well as online manufacturer sources.

Thanks for pointing that out. MOST of the time? Let's break down the way I MEANT that. Most of the time = while using BoLee = not like other books...
I have seen like Hornady might give you a min and max, and sometimes data from the manufacturers is gonna be minimum length, but certainly ALWAYS verify or crosscheck anyways the minimum or maximum. Since my loads state that they should be about 1.215 or whatever and I always seat to 1.249 for the .45 then I have no issues. I guess I should try a few at the recco depth and see if it affects velocity much...

Also, I have seen that NORMALLY the longer the bullet is = the less pressure you are allowing by making it longer = usually not mentioned in books or online... I guess, I am saying that it is almost a given that you can make your bullets a bit longer with no ill effects on pressure.
