Congrats, Franc. That is a fine looking 1891 Argentine carbine. Getting an 1891 with the crest intact is great, because many of them have the crest scrubbed.
I have several 1891 Argentine long rifles and several 1909 Argentine carbines and long rifles. I shoot them in a vintage military silhouette match and have found them to be quite accurate.
I saw the target you posted and believe that if the bore is in good shape and you work at it, you can get better accuracy.
I currently reload for my Argy's and have found 174 gr SMK's with IMR 4320 in the the 41-43.5 gr range to work well in my rifles. YMMV.
If you do not reload, I found Norma 150 gr to be the most accurate, followed by the PPU 174 gr FMJBT. I had the poorest results with the PPU 180 gr SP. The Norma was good, but
PRICY.
One of my 1909 Argentine rifles was scoped by a previous owner.
I recently went to the range to check zero on it for an upcoming match. As an experiment, I shot some Prvi Partizan 7.65x53 commercial 174 gr ammunition through my Argentine Mauser to compare to my handloads
