I have read often on the firearms forums of poor Magtech ammunition performance. I've only ever sampled their ammunition in .38 Special and .45 ACP and both gave good function and mediocre performance.
Automatics can be finicky as Mrs. noelekal's cat about what they will eat. Bullet shape, powder charge, or bullet weight may influence. The truncated cone styles are balky in some pistols, hanging on feed ramps. Same thing for some of the heavily marketed "self defense" loadings with their designed in expansion features.
It's not too difficult to obtain factory loadings with bullets having profiles that mimic the shape of standard round nose full metal jacket bullets, even if one desires an expanding bullet feature. Way too much is made of bullet expansion anyway which doesn't provide nearly the edge that many think it does.
For "something completely different," revolvers will function with any weirdly shaped bullet that fits the chambers of the cylinder.
Cylindrical shaped wadcutters are intended for accuracy and for cutting visibly distinct holes in target paper. Originally designed for target competition use, they would absolutely bedevil automatic pistols.
A ten shots at ten yards effort with one of the primo competitive target revolvers of all time, the Colt Officers Model Match, chambered for .38 Special. Long discontinued, these make delightful range toys and can yet make a good showing at a precision pistol match. This one is the same age as I am, dating to 1957. It's in better shooting trim than I am these days.
Here are examples of 148 grain lead hollow base wadcutter bullets I handload over 2.8 grains of Bulls Eye powder for use in the Colt OMM.
