anybody played with this combo. I picked up 3 lbs of H4350 already and wanna try them. I only see it paying off if I can push them faster than 2900. Just looking to see if anyone has had any luck with this bullet.
6.5CM and 130 ELD

Me learning this, I kinda feel like if I was Christopher Columbus discovering new land lol. Thanks for letting me know.
I found this thread interesting because i use that bullet from a hornady factory load. I'm getting 2700 ish in a 20" 260, and it works great. I've been good to 1200 in wind even. I use it in matches and they perform well. I've thought about loading 140s but the 130s work so we'll I'll probably stick with it. Hope that is useful to you.
Going to load up these for this weekend. Going to try H4350 and 2000MR. I am sure it will push 2900FPS pretty easily since I am already running 2800FPS out of a 20" barrel and the 140gr ELD-Ms.
Awesome. Report back because 2000MR is my go to powder in my 308! Would be very interested to hear your findings.
I have tried 2000MR before with the 140s but the are only a smidge faster then H4350, but were showing pressure signs. I think it might be too fast of a powder for the heavier bullets. I am hoping it won't show pressures with the lighter 130gr ELD, TMK or Berger Hybrid Tactical.
Did a 10 round load development from 42.8 to 45.6 with the ELD and TMK and still haven't found pressures or a flat spot in speed yet. I thought I was going too far with 2000MR with 45.6grs, but still nothing showing at 2945FPS. Might go a little faster to see. I worked more of a load up with the 130gr Hybrids and at 44gr of 2000MR it was shooting at 2900FPS, SD around 3FPS and 1 hole group.
Seems like you found a good recipe. Since you haven't had pressure issues and plan to load a bit hotter, it'd be nice if you can get that speed in the 3,000s but accuracy still beats speed imo. You'll already have something to come back to if it doesn't work out.
Awesome. I might be giving it a try too. What was you’re outside temp? One thing about 2000-MR I have found is that it is defiantly temp sensitive. Doesn’t seem to be that bad in my 308 but had a buddy load up a ladder with his 6 BR with no pressure signs in 50-60 deg temps and the next time he did testing it was high 70s and 80s and he said that all three charge weights he tried from ladder showed pretty bad pressure signs so he scraped it (this guy is no slouch and who is got me into this so don’t assume he’s a hack lol).
I guess I had pretty much ruled out 2000Mr for my 6.5CM but maybe you’ll have me rethinking things!
I loaded up a couple of more today to see if the speeds would plateau off. 3,000FPS would be stellar out of a 20" barrel, but I know it would be really pushing the limit of what I have ever read.
Temps were mid 60s. I think if I kept it around 2900ish FPS, I should be fine, especially in the hot Texas heat! At this point, it's just a experiment on how much speed 2000MR can do safely. I know on the burn chart it's a couple of heat ranges hotter then H4350 (which didn't shit for the 130s today). I think this powder should shine with the lighter 120 and 130gr class 6.5 bullets.
The 140 ELDm is awesome.
I had a great load worked up for the 130 ELDM's, but they fall by over a mil difference at 1000 yards and lots more wind than expected based on Hornady's G7 b.c.. I donwloaded Litz's custom curve and it confirmed the bullet is actually sorry beyond 600 yards. Hornady Black bullets do better at range, even factory laoded. Stick to 140 ELDM, 130 Hybrid, and 140 Hybrid unless you have another pet lead.

For reference, JP AR10 22" barrel. Node at 39 - 40.5gr of Varget. 41gr was way too hot at 2800fps. 40gr was 2751fps, SD of 10.8.
