I loaded 4 new loads (and the ramp ups) to test for velocity, accuracy and compatibility with the existing sight system on the EMF 92.

The bullets used in my .45 Colt handloads to date.

300 gr. Hornady XTP, 21 gr. H110, CCI 350
300 gr. Sierra JFP, 21 gr. H110, CCI350
260 gr. Cast Performance WFNGC, 10 gr. Unique, CCI300
145 gr. RB, 2.5 gr. Bullseye, CCI300

These are photos of the cartridges. The longest is 1.684" but still functions through the M92 action.

The longest of these cartridges is the load with the Sierra at 1.684" but the XTP has a second cannelure and can be loaded out to that length. Both will probably take the max load of 22 gr. H110 which should be very similar to that load as I use it with the 300 gr. bullet in the .44 Mag.

I've yet to use H4227 and Lil'Gun, both of which should provide slightly higher velocities if the manual is correct.

Yes, I have received the new .600" (measured from bottom of dovetail) Marbles sourdough front sight but haven't installed it yet. Perhaps my reloading will negate that necessity. That would be good as the sight will require modification, a lot of grinding, to use. I'd just as soon save the sight for another project if I can.

A comparison shot of the the factory front and the Marbles replacement. The Marbles must be extensively modified as most of the sight forward of the dovetail would have to be removed to avoid the barrel band!

This brings up another subject, removing and installing front sights. In this case the base of the original front sight was tapered in thickness to wedge into place in the center. It was heavily greased in the dovetail and can almost be removed and installed by hand but didn't come out after firing many rounds of heavy reloads. This is why one removes left-to-right and installs right-to-left. Not everyone does this sort of thing but enough do that it pays to adhere to this procedure.
