Been about a year but finally finished getting some velocity data from various bullets. I still have 147 ELD-M, 143 ELD-X, and 140 Elite Hunters and 140 Hybrid Targets available (have more hornady stuff than berger on hand).
These are what I'm getting velocity wise from a 19.25" T3x Lite barrel. Will load up a few 10 round groups in the next few weeks and make sure they all group.
Probably try 143 ELD-X, 147 ELD-M, and 140 Elite Hunters all at 42. Maybe 42.5 for the bergers.
T3x Lite w/ original barrel cut to 19.25". New starline brass 1x resized w/ CCI primers & H4350. Measured w/ a magnetospeed sporter attached to a suppressor w/ sensitivity on Hi 2.
Went through a ladder with some 140s and 143s today just to get an idea of what velocity I'm getting. 32 degrees out. 70 in the house and I brought rounds out 3 at a time and shot them in different orders each time. Just trying to see if I get pressure signs anywhere. Loaded as long as they'd fit in my CTR magazine. I have all the measurements written down and how far off the lands they are in a different book. I loaded these a year ago and never got around to shooting them. Will post headstamp pics later and see if anyone has an opinion on pressure signs. Maybe a minor swipe at 43+ but I get that fairly often from this gun so hard to say.
One thing that's interesting is that the 143s are slightly faster than the 140s. Guessing that has to do w/ bullet shape and bearing surface? 147s are also faster but it was 15 degrees warmer when I shot those.
