A new 1911 has traditionally needed about 200 factory power FMJ rounds through it to break it in. Loosen up the action, wear in the extractor, etc.
The Taurus? Would not HURT to run some through it, too.
Fire 50 or so, clean the gun. Repeat. Look for any failures of any sort. If a 1911 is hiccuping on factory FMJ, it for sure has problems that can get in the way of running lighter power lead bullet ammo.
Report back how the break ins go. There COULD be a function problem with both guns, but very unlikely. Unlikely either will malfunction with FMJ, but the object is to loosen the gun up so testing with lighter lead bullet ammo tells no lies. So, loosen the guns up before you seriously start looking for why the reloaded ammo does not run the guns well.
The ammo you have loaded at this point looks reasonable. Nose is a little flat-ish compared to FMJ ammo. That should not cause a failure to feed the last 1/8" into chamber though. Powder coating CAN cause some chambering problems. Have the bullets been run through a sizer die AFTER being powder coated? I have seen some coatings so thick or so non-slick that they cause a failure to feed, but mostly by sticking the nose to the feed ramp and depositing powder coat color there.
good luck, GJ
