Yes, it is the sights. I did publish the statistics before, on the old forum, but for those of you who missed it, here is the essence:
The GermanBDMP holds Enfield-Mauser competitions every year. There is also an Enfield-Swedish Mauser-Mauser competition in Paderborn. This is a rare case of a good number of people shooting with all 3 types on the same occasion, which gives a better basis for comparison than individual impressions. I evaluated the top 10.
The statistics results were quite clear: P14/M1917/Mk4 beat SwedishMausers, which, in their turn, beat Mausers.
