I am looking for a OAL for this bullet. All my manuals and other data are for a LSWC.

I found a box of these bullets as a shop going out of business and got them real cheap. It is bullet #810 on this link. Same as a 230 gr, just shorter base.

I loaded them to just up to the driving band and the OAL of
1.228 to 1.230. So does that sound right?. I test fired 20 of them today and the fed through a SW 1911, SA XD and a Sig.

.45 ACP CALIBER/45 COLT/454 CASULL at .40 CALIBER HARD CAST LEAD

That seating depth will do just fine.

The only real concerns when finding a COL or seating depth are:
1. the loaded round must feed in the magazine
2. the loaded round must chamber and allow slide to lock
3. the loaded round must not exceed cartridge chamber pressure specifications.

For the last item, you rely on loading manual charge tables. And make sure that the bullet you are using is not heavier than that specified for the powder used.

Yes, but for #3 the pressure will be determined by the volume in the case which will vary by how far the bullet is seated. For instance the Lee data (compiled from other data) lists a 200 gr bullet but does not list the exact bullet and only lists a Minimum OAL . All my other manuals list SWC which are entirely a different bullet shape.

I could probably have this bullet work at a 230 gr OAL of 1.260 all the way down to 1.200, hence my concern.

The bullet design will give you major clues for intended seating depth:

When the bullet has a distinct shoulder, that shoulder should not go below the case mouth.

In the case of the 200 g RN bullet you showed, seating it an extra 0.060" deeper than you would a 230 g RN bullet is not going to hurt anything.

It's the extreme situations that can bring problems. The one and only handgun I have ever damaged with handloads was a cheaply-made breaktop blackpowder .38 S&W caliber. The starting load of Bullseye powder was corked with a 148 g WC bullet because I didn't have any 150 g RN bullets. One of the first cylinder loads burst a chamber. A gunsmith examined it and said that it was possible my load did not do the damage to the cheap steel of the cylinder. That made me feel better, but I have been careful not to repeat the experience.

Thanks. I loaded them to just show a fraction of the driving band. That's where the 1.230"ish oal came from.

It seems right and looks right but I am OCD about these things
