As you can see almost any fast-burning powder and a +/- 200gr bullet will work in the 45acp.
Reddot is ok for blamo ammo/range fodder. but I never could get it to keep up with aa452, wst or bullseye.
Used to shoot nra bullseye (50ft) so that's what distance I'd test at. Always used a H&G 68 or 69 clone and would do ladder tests with bullseye. Back in 2011 I sold all my 1911's, s&w 41's & several other target pistols. Thinned the herd so to speak. Bought a nib springfield range officer and a marvel 22lr conversion kit for it.
Showed this target before, nothing more than the test target used that day testing loads for a nib springfield range officer. Tested 3.6gr, 3.8gr & 4.0gr of bullseye, ended up with this 10-shot group @ 50ft.

Soft shooting for 1 handed nra bullseye using a Mihec h&g 69 clone (200gr swc) with the standard .468" crimp/ 1.250" oal doing +/- 775fps.
Back in 2014 I ran across a pretty good deal on powders so I bought a couple 8# jugs.

As already stated a 45acp will run on pretty much anything. With 16# of clays laying around I figured it would make a good blamo ammo powder for the 1911/45acp. So I used all of the +/- 200gr 45cal bullets that I cast (sold most of my molds and down to 3 +/- 200gr 45cal molds) and did 2 test loads 4.0gr and 4.3gr of clays and the 3 bullets I cast.

Left is a cramer 5f 200gr swc that's actually a hollow based version (175gr)
center is the H&G 69 mihec clone
right is the mihec 200gr fn hp
Anyway 5-shot groups @ 50ft testing clays and 3 different bullets.

The 4.3gr load and any of the 3 bullets I cast turned out to be pretty decent blamo ammo/range fodder plinking ammo. The loads are doing +/- 850fps. A little snappy for 1 handed shooting, as you can see I struggled to keep all shots touching @50ft 5 shots in 30 seconds.

It's actually pretty hard not to find good loads for the 45acp.
