can you check this with quickload please

Just curious, as to what quickload might come up with on this one.

Yes, it's very light, I know, that's what I want.

1911 .45acp mil spec

win brass, win primer
4.0 gr win 231 ( approx 1992 vintage)
200 gr swc, HG 68 clone

Thanks in advance.

It's not that light. You need to give me an OAL to get a value out of Quickload, but it will be over 800 fps IMO. 4.8 grains makes major in my 5" pistol.

I got 750 or so using 4.7 in mine. Too many variables to make any real estimate beyond generalizations.
know anyone with a chronograph?

Coal is 1.268

I loaded a box of these and was quite disappointed.

First, it wasn't as light as I thought, BUT it was also too low of pressure for the case to seal the chamber.

Noticably sooted brass, the feed ramp looks like it was spray painted with charcoal, and noticable smoke. Poor groups, about 6-8 in, admittedly freehand.

Also, after my son shot about 4 or 5 of these, he started ducking his head sideways, saying they were blowing back in his face.

Well, that's enough of that.

Last weekend, we shot this same pistol, with a load of 3.8 gr trail boss. same brass and boolit. maybe CCI primers, can't remember exactly.

The gun was nearly clean after 50 rds, the group was 3 in (again freehand) , and no ducking nessassary.
I would be happy with that, but the group was also about 4 inches low. This pistol has fixed sites.

I wanted to try other loads to see if I could get closer to the point of aim, while still keeping a lower recoil load my son could shoot.

I also have 700x on hand, I'll try 3.8 of 700x next, with all other componets the same.

Could someone please run quickload on that. Thanks in advance.

Well, I was wrong. Using your OAL of 1.268, (which is quite long for #68 copy) Quickload gives only 662 fps. Even with an OAL of 1.20 it only yields 690 fps. And you are running around 8,400 psi in a cartridge with a CIP max of 18,855 psi.
