Gmoody: Sorry, yes I was a bit unclear. Loading .45ACP, and was referring to COL, not case length.
Thanks for input. Yes, I have decided (affirmed by you folks) that the correct COL is 1.235.
Now, since a lot of the data I had (three of four sources) are based on 1.190 length, with loads of 4.2-5.0 grains, I'm betting that my loads are gonna be too light.
The one set of data with the COL at 1.235 shows powder at 4.9 - 6.0
Ho hum...Gonna have to see if they go BANG or poof.....Will make sure to take a 'pushrod' with me to the range. I'm wondering if it will even cycle the slide. Built three levels of rounds, 4.2, 4.4, 4.6 grains respectively with Bullseye powder. Hopefully these will at least cylce the slide and push the round to the target. If not, I'll get to try out my new bullet puller!
I'm new to reloading, but sure am enjoying it so far! Fun stuff...
P.S. Hand cycled a few round (without fireing) and they seem to feed thru the mag without issue, but it does look like that's about max length for the SWC's
