Here is a test I did of Match powder with a Hornady 123gr ELD-M bullet in a BCA 20" upper. I used a Magneto Speed V3 chrono mounted on a Wiser Precision picatinney mounted at the muzzle to get the MV and each shot was .2 of a grain apart. I have found that you can pick whichever node you like and it is accurate. I use Match in my 5.56-223Wylde also. This data was from a 65 degree day if I remember right. Its funny most of the other powders that I have tested in this manner have maybe 2-5 nodes but Match had several as you can see. I added the 2520 chart that I did with this upper just for comparison. The 2520 test was with a Nosler 123gr CC. I have never been able to get 2520 to shoot in this upper but have found good loads in my 223.
I should also add that at the bottom of the node where it goes to the lowest point I found that testing .1 grain on each side seems to be the best for accuracy of that node. I used a Hornady case with CCI450 primers. I seated the bullet at 2.245" and I haven't had a chance to really find the most accurate load or change the seating depth. I plan on doing that when the weather gets better.
In a side note since it has been mentioned in this thread, I did test SW Precision against H4350 in my Ruger PRS 6.5 Creedmoor and I got about 50 fps faster muzzle velocity from Precision. But I will have to say that that gun loves H4350. This was with a Hornady 140gr BTHP and Winchester LR primers with a Starline case with the necks turned and the bullet seated at 2.800'.
