Regarding the 8M3 "Effect" JHP
Many, many, many moons ago I did a photographic comparison of the the various 8M3 bullets on the market on Arfcom, another fella did the same on M4C. I used bullets from the "Sapsan" birdy box, the original blue and white Ulyanovsk box, the first batch of Wolf Military Classic (lacquer case), and the newer Wolf offerings with the poly case coating. I cant find the pics anymore because of Arfcom's crash a few years ago, but I remember that the Sapsan, blue and white box, and original WMC had 4 Vs cut on the inside of the jacket. These were the only Russian JHPs with the cuts.
Of note, there is question as to if the 124gr JHPs coming in as Wolf Military Classic and Tulammo are 8M3.
