I'd have to go with a 200gr swc h&g#68/69 or a clone/copy of that bullet. They are about the easiest bullet to reload in the 45acp.
A couple myths/swc 45acp feeding issues:
The magazine being used plays a huge difference. 3 different styles of 1911 mags. The usgi feed lips on the mag on the left are lllloooooonnnnngggg. The hybrid & wc mag lips are shorter for a earlier round release needed for the shorter jacketed hp's and the lead short nosed swc's.
Enter the h&g #68, it was designed to mimic the usgi hardball bullet profile and feed at the same place on the nose while maintaining the same shoulder height from the base of the bullet.
What makes the h&g68 easier to load is the reloader can clearly/easily see the shoulder line of the bullet. Some h&g #68's loaded, you can clearly see the shoulder of the bullet sticking above the top of the case.
What's happening is this. As others have already stated, the 45acp head spaces on the mouth of the case. Most 45acp semi-auto bbl's have chambers that are cut long. That means that oal is actually set by the shoulder of the bullet. Hence the plunk test. Once you've found that distance the bullets shoulder sticks out of the case. It tells you the starting point to test other bullets. Things like too long of a oal (will not fit mags) & failure to feed because of an odd nose profile come into play. But you at least have a place to start.
The h&g68 also takes things out of play like throated vs non-throated bbl's that can and will change the oal/shoulder height of a rn bullet. But will not affect the h&g68 swc nose profile.
The h&g is just an easy bullet to reload and has excellent visual characteristics.
Other things to do:
Expand your brass to the point that they are over expanded. Proper bullet seating/alignment is more important than brass. It's nothing to get 30/40/50 reloads out of a piece of 45acp brass. Wearing 45acp brass out should be the last thing on your mind.
Seat and crimp the bullet in different stages. This simply takes the differences in brass (length/thickness) out of play. Thicker/longer brass tends to bite into the bullet before it's fully seated because the die crimps is starting to crimp the bullet in place before it's fully seated. Some people use a lee factory crimp die, other do not (I do not use 1 myself).
Most of all, take pride in your work/craftsmanship. Quality over quantity, accuracy over good enough, reliability over volume. I've shot loaded over 10,000+ of those h&g#68 rounds pictured above. I have not had any issues of any kind, no ftf's/fte's or any other malfunctions of any kind. Hit the loud bullet and it not only goes bang every time, it actually hits what it's being aimed at.
