    Loads for the old USGI 1911s

    I haven't been on here in seems like forever but I've been shooting one of my old Colt's recently and was curious, with all of the CMP 1911s out and about, what people's experiences have been. I replaced all of the original springs with a Wilson Combat kit first. I've been using 4.4 Bullseye with 230 FMJ and it shoots great @25. I didn't want to, or feel the need to, use full power factory loads. It actually feels like I could reduce a little more but I'll have to try it an find out. Anyone else?

    I had read somewhere that Bullseye was the powder used in the original load, though that may be fable.

    What muzzle velocity does your load generate?

    My approach when my cmp gun arrived was function text with standard 230 grain ball. ( I replaced my recoil spring with the Wilson flat wire just because I had it laying around and seemed like a good idea)
    I made some loads with 200 grain round nose that were what I call mid range ( meaning if the manual said minimum load was 4 and max was 6 I loaded 5 grains) and they ran. Then I started experimenting with some 200 SWC and even 160 SWC not expecting them to run, but again at mid range in powder charge they worked fine, so I started dropping charge weight by .2 grains until it didn’t run then went back up to the last known functional level. No need to beat these guns up too much, and I don’t have a chronograph and how fast they are going doesn’t matter at this point.
    For old guns my general approach is the lightest load that runs is the answer.
