I'm reloading 45 acp 230 Winchester 231 The question every manual OAL is different. 45 acp Win 231 4.7. Hodgdon OAL 1.200 Lyman 1.275 and Speer 1.270. Which one do I go with? I know this has been brought up before. I'm still new to reloading. I'm thinking just go with the 1.275.
What does everyone else do? I have tried all the diffent oal. Hope you understand what I'm saying, I don't.. Could be winchester 700x , titegroup,all diffrent.
 
Yep, with a 230 Gr RN I load so my rounds fall between 1.260 to 1.265. Forget the manual, besides that Hornady 230 Gr is a flat point, thus the 1.200 O.A.L..

1.275 is SAMMI max, and is a tight fit in some mags.
 
Thanks alot for input , I was going to change the lenght, but not sure how much. I started to lenghthing it but did'nt know how much. Now I have something to go with. I was also getting some misfeeds.
Thanks Again

Set your seating die with a factory hardball round. That's what the gun was designed to feed.
 
GI issue .45 ACP FMJ-RN and National Match 230 grain hardball is loaded to 1.266" Min to 1.271" Max OAL.

If your bullets are similiar in profile to a GI FMJ-RN bullet, that is the OAL you should use.
If is some other shape like FP or JHP, all bets are off.

You wouuld then need to use the barrel out of your gun as a guage to see what length will chamber without the bullet hitting the rifling leade.

Hey John BH,
I have been reloading 45 ACP for about 2 years. My reloading records confirm about 45oo rounds loaded and fired over the last 2 years. I'll try to stick to useful information you can perhaps use.
A. I use Berry's preferred plated bullets, both the 200J HP's and the 230 grain RN's. for general purpose shooting. I will jump to better grade Hornady bullets if I am shooting for performance or friendly competitions.

B. RN's appear to be more accurate than the HP's, but of course cost more.

C. Berry's bullets bought in bulk (1000 or more) directly from Berry's are cheaper than Cabela's, etc....as Berry's pays for shipping.

D. I've used all the popular primers out there. I recommend them all EXCEPT Wolf's. My Wolf's no-fire to often for me at an approximate 8-12% failure rate pretty consistently. Yes, it could be my handgun (Springfield XD, long barrel, tactical model) but I never have problems with any other primer. I recently have found a lot of Winchester primers (brass) tend to stick out a bit (about 0.000 to 0.003 inches) from the brass when loaded. Yea, pockets all cleaned and measured to size...hum.....but no mis-fires or jams though.

E. I use Winchester 231 and WSF and do not see a lot of difference between them in terms of performance. Here's the reloading data I use for 200 grain HP's Berry's bullets and the powders:

200 grain,HP, WSF=6.6 grains,860 feet/sec
200 grain, HP, 231 =6.1 grains, 850 feet/sec.
COAL: 1.220 inches

F: I have had 3 shells discarded over the last 2 years for cracks at the bullet end. Otherwise, the 45 ACP brass seems to last forever. I even measure the length.
G Jams- Also, I had some jams in the early days when I was just starting. I found that I was not running the shells far enough into the RCBS brand die after the mouth had been expanded. Thus, the bullet end of the brass was a bit oversized. I discovered this by measuring the OD...so I re-set my die settings and, very, very few problems after that.

Hope this time I took helps out another re-loader.
 
"The question every manual OAL is different."

But...but..everyone says we NEED multipule manuals to compare! ( Wonder if they're wrong about the value of that?)

Anyway, the differences in OAL can either drive you crazy OR tell you it ain't all that critical. Do like all experienced loaders do; seat 'em so they will feed and chamber reliably in YOUR weapon and be done with it.
 
Bullets from various manufacturers have different shapes and nose taper. Other than keeping the cartridge OAL of the .45 ACP at or below the maximum SAAMI 1.275" each particular bullet make is a rule unto itself. Generally seating so the case mouth is just below the start of the bullets ogive or taper will insure best feed. You should chamber check the rounds OAL using the barrel removed from the gun and compare to a factory round to ensure that the bullet isn't engaging the rifling before complete chambering. If it does you need to seat it a bit deeper.

The .45 ACP case has plenty of volume, the cartridge pressure is relatively moderate and OAL isn't critical to chamber pressure like you can find in small volume cases.
 
As you see most of us are suing between 1.260" and 1.270" for our .45 Auto ammo. I agree you might not want to use 1.275" because like said above, that's the Max and might be troublesome in some mags especially if you're off even .001".

The OAL listed in the manuals isn't "law", it's just what they used when testing their load data. It's not written in stone that you must use that length. Also, that length is only important if you use the same exact bullet they use in the manual. Their listing is a guideline, not a must. Just remember though, if you shorten the OAL you are taking up more space in the case than they did which will raise the pressures, sometimes by a lot in small cases like the 9mm. You will get the feel of things as you reload more, not to worry...
 
OAL for the .45ACP depends upon the bullet used and your particular handgun. A friend gave me some commercially cast Lee .45-230 TC bullets, and they have to be seated to an OAL of 1.150" to work in my Gold Cup, while other guys can seat them out to 1.2".

I measured a box of GI NM ammuntion and decided on a nominal 1.265" OAL with GI 230 FMJ RN bullets. Now that I am out of these I am going to use that OAL with the Rem FMJ's I bought.

I purchased a bunch of 230 LFN from Bull-X. These were truncated cone and my OAL was 1.200". That worked fine in all my M1911's and I shot some in a SIG 220.

For 230 LRN I am seating them to a nominal 1.250". All of these measurements are averages as bullets all vary a bit.

What is most important is that I get 100% function.

I favor seating bullets shorter than longer as I found throat distances vary depending on the barrel. I had heard "the way" to determine OAL was to seat the bullet out until the back of the case was level with the hood.

This worked well for that Colt. Then I tried running those loads in a Kimber. My loads were too long for the Kimber and jammed in the throat. The pistol would not go fully into battery so I could not shoot them out. I could not beat the slide shut with my hands. They were jammed in the throat so tight that it exceeded my hand strength to rack the slide.This is when I found out recoil spring guide rods are a bad, bad, thing. With the standard recoil spring plug I could put the muzzle with plug on the edge of a table, push down on the grips and eject a round. The bad, bad recoil spring guide rod prevented that.

I learned two things, 1) dump the guide rods and 2) seat my bullets a bit shorter.
 
What is most important is that I get 100% function.
Yep, I chose 1.260 to 1.265 for the same reason. It works in all my guns. If 1.255 or 1.270 shot a hair better, I could never prove it, but I am not shooting Bullseye either. Just general shooting. :)
 
Whatever works in your gun is the best OAL.

I have a custom 1911 that won't feed 230gr. JRN bullets over 1.255.
Same gun I use 185gr. LSWC in comp. that can go as long as 1.270
The shape of the round makes the difference.
