What's minimum COL for 45 ACP?Of course seating within specified COL
I shot a match last month next to a guy shooting lead slugs (no nose, like a full wadcutter) in 45acp seated flush with the case mouth. I think he won the 2700 and the SP EIC like that. SAMMI etc aside I think it's whatever will cycle. Magazine feed lips make a big differenceWhat's minimum COL for 45 ACP?
Haven’t a clueWhat's minimum COL for 45 ACP?
Mine is all about feeding reliably but have never even thought about something like that regardless of COLI shot a match last month next to a guy shooting lead slugs (no nose, like a full wadcutter) in 45acp seated flush with the case mouth.

In that spirit, here is a picture of two different 200gr SWCs I use, also at 1.250”
Do know my pistols won’t take an SWC below 1.245” (reliably that is).
So shoot them in the Eclipse and be done with them.
With that much bullet sticking out of the case I'm surprised they loaded into any chamber. I would load those with about 1/3rd of that front driving band sticking out of the case.
Interesting. Max COL for the .45ACP is 1.275", mine are seated at 1.250"... 'that much bullet' sticking out of the case shouldn't be an issue.
As Frog says, if you want to quit having those "at the range" moments, buy a gage. I don't care if it's Wilson or Hornady or Lyman or whatever, it's the only way I know of to reliably load for several pistols of the same caliber. Mine stay right on my bench.Did you check them with a case gauge?

I guess your COL is the same provided bullets are same dimensions lengthwise. But OP’s aren’t do you think?I load every SWC the same, my seating stem seats off of the shoulder.
I can change from a 200gr SWC to an 160gr button nose and everything in between and they all seat to 1/16 of the shoulder showing.
That's not how max COL works. Most bullets do not get loaded to the max COL.
I think mdi nailed it. In this case, with that bullet design, the seating depth is less about COL, and more about how much of the shoulder (front band) is exposed.

Well it gives me a headache so I just keep it simple and pretend life’s that way tooI would agree... it's not about the COL, it's about the front driving band. As I mentioned, they plunked, and chambered from a magazine fine... in certain pistols.
Here's what's interesting... if I am to believe my notes. CQB mentioned those two bullets he has loaded, and I've got load notes from 2020 when all I could get was some Rainier plated SWC's. I loaded those to 1.265"... I don't know why, it must have been in one of my data sources, very likely Alliant, because I was testing SportPistol and BE-86 at the time. Granted, and as CQB's photo shows, the ogive on the plated bullet is longer when compared to my cast bullet... so there is something to that; I don't remember an excessive amount of bullet shoulder sticking out. I didn't have the 5" Kimber at that time, and they shot very well in the Eclipse, as well as the ProCarry... when they would feed, for they had a tendency to hang a little in the ProCarry.
I was just curious what everyone else has seen or experienced. I don't think I'll get any more of these, my friend actually bought a different mould for 200grn .45's... so that's probably the end of them.
This how I seat mine and never have a problem...light taper crimp.Ok, I agree with what others have said, it should be seated deeper.
You should seat it so there is only about a 1/16 of an inch of what you are calling the driving band above the case mouth, most people will say a thumb nails amount.
I use 14 magazines each week. When I shot SWCs routinely I could tell you which mags would contribute to poor chambering because round was too short, etc.I also recall reading about .930" from base to shoulder of bullet. The swc's feed great in my three Kimbers. I would say they are flawless, but I do get one once in awhile that hangs up, usually due to the gun needing cleaning.

Some people go by a head-to-SWC shoulder measurement; .936" is on the high side, I have seen as low as .924".
