Finally I got to try out my two new babies from Inrange, took all my AKs, 1 Sar-1, 1 preban Norinco 7.62 underforlder, and finally my new Inrange customs 47 and 74. The two inranges fired flawlessly not one FTF or FTE. I fired about 200 rounds from my 74. It was my first time firing the 5.45 and I have got to say after the pounding on my shoulder from the 3 7.62's the 5.45 was a welcome. I placed a target about 50 yards away and the 74 had the best overall grouping. My other inrange grouped more to the left but so did my underfolder, so it's possible that at 100 yds the group with the bullet spin will go more to the right. The only problem I had was with my chinese 75 rounders but I think I did not load them correctly. I was at the famous Pop Dean's range a South Florida icon and musta fired about 700 rounds total and even bump fired my already broken in Sar-1 and Norinco, that the friendly Broward Sheriff stopped by and asked me if I was firing any fully automatic weapons, I asked him if he wanted to fire any of my weapons and he smiled and waved goodbye. I wore my Inrange tee and overall I have to say that I had a good functioning day. now that I know where the rifles more or less shoot I will take them individually and see where they shoot. As soon as I can I will upload pics.
