Marty and I have been testing this faster burn rate type duplex for a month or so now. So far it has been very reliable for both of us with the 195bx. It seems to really keep constant POI and seems to consistently shoot 1 to 1.5 moa to 300yds.
TG traced this for us a while back when we settled on the better shooting ratios.......after seeing the trace shape, time, pressure and burn characteristics I see why it shoots so well for us.......
As of today this is my hunting load with 195bx. I see us getting more speed than Dennis did today so am wondering the difference but it does shoot good.
With the 2015 and H322 duplexes 2 important things I have noted::::::::::
First noticed that the end 6 inches of barrel get hotter quicker than the rest of the barrel.
Second notice pretty big muzzle flash at dark.
IMO Both of these traits confirm the realism of the 2nd spikes most loads are giving us with the 200 class bullets..........
I am not experiencing either of these with this load type. Loads to test in this type load are 10/50.......11/49...........12/47 or 48.
Again thanks to TG for helping us work thru the unknown......
