Finally had the opportunity to get to the range yesterday.
Loaded 3 at 45.0, then one each of 45.5 through 48.5.
Shooting 143 eld-X, with .040 jump.
45.0. = 2652 (clean bore)
45.0 - 2600
45.0. - 2599
45.5. - 2615
46.0 - 2657
46.5. - 2734
47.0. - 2760
47.5. - 2774
48.0. - 2816
48.5. - 2844
I thought that I would have seen more velocity, but I still have room, no pressure signs at all, primer edges still rounded.
Going to load some more up, start at 49 and see if I run out of room or hit pressure.
Never saw an accuracy node, barrel is new, total round count is 43. It does shoot 140 hybrids and 45.5 h4831 well (fire forming) but velocity is around 2670. Going to give the rl26 a second try, if velocity doesn't get to 2900, with an accuracy node, I'll run the h4831 up to pressure and see how it groups.
