I tried 2.885 and 2.880 stepping down to 2.860, adjusting the powder downward to keep near ~2715 fps
Both of those shot well.
The 2.880 is about 0.015 off the lands and is what I'll use for now.
I don't crimp these, so didn't want to chance a stuck projectile on a manual eject.
But don't know what the full temp range was, sorry.
Superformance 2.08 fps/deg
IMR4350 1.54 fps/deg
Those seem a little high, and expect H4350 to do much better.
I posted this chart elsewhere, a collection from www sources, fwiw..
(Test conditions are unknown)
Thinking maybe time for a new barrel.
Compared 140 ELD-M COL to lands against new barrel and saw 0.027" erosion.
Adjusted the 140 ELD-M load for 2.880" and back it came, this at 400 yards.
Then I'm not launching them at mach 10 either..
Hard to beat 41.9 gn H4350 under a 140 gn pill, in my SAV 10 (24" w/break), Hdy brass.
Also need to adjust for case capacity since HDY is more than Lapua, in order to get same fps from both cases.
Usual caution applies,, to work up the loads from a safe starting point..
I'd stay with the ELD-X and just hunt close around the 40.5 gr level.
Have two RAPS and they're both keepers.. (243 & 6.5cm)
Also working with Game Tipped 130s (GTK).
Little more expensive than ELD-Ms but getting 1500 TMK at a time sounds like a winner.
... 95gr Vmax to try next for a lighter round....Had good luck with them pushed by 41 gn of 8208 xbr,, got about 3200 fps from a 24" barrel.
...looking hard at the tipped Game King in 130 grain. ...Welcom LIT, and that's one of my favorite 6.5 pills.
I use Varget under that one and H4350 or H100V under the 140s.
Updated the chart above and made the units more clear..
Paper definetly says @100 yards MOA =1" and Mil-Dot = 3.6"
Here's another source Trijicon
You guys that use Mil-Dot should chime in here....
