SNS Casting .45Auto 200gr OAL? Help.

[cmann]

I purchased some SNS Casting Coated 200gr. RN bullets for .45Auto. https://www.snscasting.com/

These bullets have a cannelure. I am looking for a recommended OAL for these. Do I just seat them past the cannelure? I use the online Hodgdon website and they are recommending OAL of 1.225" Anyone have experience with these bullets? Any input would be appreciated. I have attached a couple of pictures of the bullet.

Those should be the same length as a 200gn SWC (.645"-.650"), so you're good with the Hodgdon data. I'd start with an OAL of 1.240" and see how they plunk in your chamber. At that OAL the case mouth should be about where the black line is in the below picture. What powder are you using?

Nomenclature: THAT is not a CANNELURE. That is a lube groove. Cannelure is used for a "roll crimp" to crimp into.

45 acp uses a "taper crimp". So just ignore the groove. Seat wherever above it gives a usable OAL in your magazine, that functions reliably in your pistol.

EDIT addition;

The bullets in your pic appear to be the same as those in this link. Showing them LUBED. PC bullets don't use lube.

Thank you for the responses. Yes, you are correct. It would be a lube groove. I am going to load them up with Auto Comp.

Seat it just shy of the forward edge of the forward driving band.

Somewhere around a 1/16" to 1/32" before the edge starts to round off a bit so the case mouth is still on flat surface, that allows the case mouth to be proper diameter for head spacing.
For case length all you really need to be concerned with is magazine function.
