It was bought used...
So I don't know how many rounds the original owner put through it. I have put about 600 rnds through it, and it has been "pretty" reliable, but not 100%. I have had 2 fail to feed with the stick mags (I think the same mag, but I haven't narrowed it down yet) The drum has proven to be very disappointing. I have only used it 3 times, and it has not worked right yet. All but 50 rnds have been reloads, most with 230gr LRN bullets, but some 200gr SWC and some 185gr JHP, all of which were just ammo I had loaded for other guns, not tailored for this one.
The gun is unbelievably heavy (it is the all steel version), and has a long heavy trigger pull, about as stiff as well done pasta. In spite of that, I have gotten 5 shot one hole groups at 25yds and I have been able to hit the 200 yard gong at the range using the ladder sight. The gun is very stiff to cock, and the drum requires the use of a "third hand" to remove it from the gun. My Daughter had trouble using it on her last visit, said "I can barely lift this!" I gave her the Viking answer, "Grow stronger!". She did, at least well enough to slam a few rounds into the 40 yd plate in the backyard.
This is a fun gun, not very practical because of its great weight and poor ergonomics, but it is a fun plinker. It is accurate, but difficult to shoot off hand (the weight) or from a bench (the shape), but these things can be overcome. As a display gun, a plinker, and the civilian legal version of a classic first generation SMG it is very nice. The SBR version would be even nicer, but the extra cost and the hassle of registration put it beyond my interest. This 1927A1 (deluxe) is just a semi-auto rifle (legally) the same as any other. It just looks BAAAAADDD! One of these days I'll get the violin case, and maybe the pinstripe suit, snap brim Fedora and spats to go with it.
