No disrespect to Jgardone or any other new reloader, I consider all reloaders friends and brothers.
Sometimes new reloaders make choices and then have a little difficulty.
No big deal, we'll try to help. Sometimes that help is offering a little education
on the selected components. I hope this helps.
The lead semi-wadcutter is an odd bullet. It was never intended to be a 'beginners bullet'.
It was devised as a specialized target bullet for slow fire accuracy match shooting.
They even developed specific magazine lips and mag followers for it,
and special target loads (very accurate loads!) have been developed
that differ from typical 200 grain lead bullet loads for the 45acp.
It's not a typical critter, it's a very specialized one.
It surely can run in (nearly) every 1911. Millions are loaded and shot every year.
But it's not a conventional bullet. Being brand new at reloading and going straight to
nearly the most difficult bullet to load and shoot successfully may be an unfortunate choice.
Some guns (and reloaders) get success right from the beginning.
Others struggle and never really get it to run. Even some experienced
reloaders have trouble with SWC in guns known to run perfectly well.
It might be a perfect choice, it might be a very unfortunate choice for others.
4.7 grains W231/HP38 with 200 grain semiwadcutter is mid-range load.
It isn't too soft by any means, but soft vs heavy is also relative to each gun.
Depending upon the springs (recoil and main), firing pin stop, tightness of the gun,
and the weight of the slide (you didn't even think of that, did you?) one gun's
lighter load may be another gun's hefty load.
The first effort at solution is to verify all dimensions of the cartridge and the gun itself.
Experiment with different cartridge lengths, powder charges, crimp diameters,
sizing die adjustments, recoil springs, lubricants, magazines, grip (meaning
the way you hold the pistol, not the grip panels you exchange by unscrewing
the grip screws). Seek the combination that works for you and your gun.
Some solutions are just bandaids to the real issue. Finding the real issue
and resolving it may take much more time, effort, patience, and sometimes luck.
Or, buy round nose 230 grain jacketed bullets. Load and shoot 500 of them.
Or maybe 1000. Or maybe 5000. When you get really good at this reloading thing,
then try different bullet styles, materials and weights.
The 230 grain round nose fmj bullet is by far, and I mean FAR, the easiest
to load and shoot in the 45acp 1911 pistol. By FAAARRRRRR.
In these tough times, it's hard to find 230grain fmj.
Even 230 grain round nose lead is easier to load & shoot than SWC.
But it may be necessary to just keep working with what you got
until you succeed.
I think I would carefully increase the charge by 2/10, then another 2/10,
the another 2/10 grain of powder to see if that helps overcome the problem.
If those loads cycle the gun, are easy to shoot, and accurate then
you have your solution. If they cycle the gun but aren't as accurate
then try a softer recoil spring and go back down to 4.7 grains or so.
Just to repeat, so I save a lot of you from posting otherwise,
the 200 grain lead semiwadcutter can run perfectly well in most 1911 pistols.
It isn't impossible. But it's not a slam dunk guarantee either.
It's an odd bullet. Keep that in mind.
And if all else fails, go back to your reloading manuals and read every chapter
from beginning to end. Reinforce your knowledge. Many of these problems
are resolved in the head, not the gun.
Best of luck.
