ELD-M's. So with a 24" barrel and obviously lighter bullet I should be looking to achieve at least 2900+.

I am going to run an OCW soon, loaded 41-42.8 H4350 in Peterson brass for an AR 20” Krieger 1/8. Hodgdon says you can stuff H4350 behind 107 SMK up to compressed loads but I am not going to do that for a semmi.

Originally did 41.0-42.8 but had no signs of pressure problems so went all the way up to 44.0. Still had no signs of pressure. Went with nodes 43.5 and 43.9 to narrow down a load. Had another one at 42.9 but didn't see the point in chasing that with the other nodes with higher MV.
43.5
averaged: 2867
ES: 5

shot .4 MOA. Very pleased with this load! (never thought I'd reach the holy land, haha)
43.9
averaged: 2888
ES: 15
SD: 5.8
shot .5-.6 MOA. (This was also a compressed load)
Im thinking of sticking with the 43.5. I don't think an increase of 20 FPS is worth giving up the consistency I was getting with the 43.5. Also maybe thinking of trying for a higher node since Im still not seeing any pressure issues.
Next, is off to the 1000 yard line to see how they do. Just waiting for good weather. Will update.

If you can't get h4350 at your LGS, but they have a steady supply of Varget.. you should stick with Varget.. it's #2 on popularity so should be a butt load of data out there...
Just do the 10 shot run up go from the bottom going up by .3 grns and look for a flat spot
Benchmark works fine; excellent accuracy in Hornady 120 ELD-M, and the only drawback on heavier bullets is lower velocity. Benchmark meters great, too.
possibly some useful info for someone...I have been doing extensive load testing with my 6.5cm 22" barrel. I've ran ladder tests using Hornady Brass, Alpha LR brass, RL 16, with CCI BR2, CCI250, FED210, WLR with 143gr ELDX
I had a decent load using Hornady brass with Fed 210 and RL 16 43.3gr with a SD of 8 @2860.
But yesterday I found Alpha Brass, WLR primer, RL 16 39.6gr @ 2744fps with a SD of 1 and ES of 4!
groups are 0.44MOA at 400yds so far out of my factory Christensen Mesa with only a bedding job.

I would venture to say a combination of BC, velocity to keep it supersonic, stability and accuracy with the given rifle, and consistency within the bullet lot.
Finally tested Varget with 120 ELD-M and found a good load.

Hornady annealed multi-fired brass
120gr ELD-M
2.14” CBTO
Avg velocity was 3018 FPS

Group was high because my dumb ass had it up a click. 5 shot group is about 0.37”. I’ll take that.

Off topic.. Advisable to use 120gr in a precision rifle class that shoots out to 1K? I'm not sure on the wind conditions where I'll be attending. It's in northern Texas.

Wow that seems like really good with the RL-17. I thought people were reporting it was too slow?
It is temp sensitive and my barrel is getting old. Used to be 2797fps with great consistency it's first summer
40.1gr Varget behind 130gr Hybrids does very well. 2900fps and tiny groups from my 24” Bartlein barrel. Check out my post on page 19.

43.5 is right where both my creedmoor's shoot well with most 140 class bullets and 147 ELD-M also. With that seating depth, how far are you jumping those hybrids? I bought a box to try out and using the hornady oal guage I found that to get to the lands with this bullet my oal is 3.008" in one rifle and 2.953 in the other. I am curious what amount of jump is working for everyone with this bullet
I run them at .030" off the lands and that's working well for me. I'm right at 2850 fps in a 26" 8 twist.
Has anyone tried the new Superformance powder that hodgdon put out with hornady? It's velocities are about 100fps faster than all other powders according to their reloading site and the hornady manual.

What charge weight? I have similar setup, except using Norma LRP (BR2). RL16 - 42.3 -~2835fps with 140gr ELD-M
I guess that info would help, sorry about that. I've updated the original post. It's 42.0 gr RL16.
How are you getting 45 gr of H4350 in Lapua brass. I'm crunching 43 with a 4" drop tube.
It was a little crunchy but it fit with a 130gn bullet.. Maybe I was throated longer? I no longer have the rifle and I don't use Lapua brass anymore - otherwise I'd give you a better update. I've since switched back to Hornady brass but kept with the 130's. Backed it back down to the 2880fps (42.8gn) load and its been running great.

I fell just short of shooting clean scores with this load at the last f-class match. I crossfired in the last string. RL-16 is no joke.
I will have to keep working with RL16. I had an SD of 12 on one of my better grouping loads. I'm just trying to run my stock of 4350 out before dedicating my loads to RL16
Just starting to load for 6.5 creedmoor. Picked up some lapua Brass, some H4350, and some CCI-BR4 primers. Projectiles is hornady ELD-M 140 grain.
Where would you guys start your testing at? Hornady book has min at 38.5 gr and max at 41.5 gr.
Going to be shooting them out of a RPR with a 26” Hawkhill custom barrel 1 in 8 twist with a conventional 4 groove.
Was thinking about starting at 41 grains as a starting point based off what I am seeing. Anyone think that’s too hot?

Manufacturer safety and fear of lawsuits keeps them low. Most on here are using 42-42.7g of 4350 with 140 Pills.
I am pretty new to reloading for precision and am hoping for some input. Just got my magnetospeed chrony in the mail this afternoon. I already had my ladder test loaded up and waiting for it. I was going for a “Satterlee type” load development test just to see what kind of results I could come up with. Also to find the max charge weight that my rifle can safely handle, a Bergara B14 HMR, 22” barrel. I started my load at 41.0 gr of H4350 and loaded up to 44.0 gr in .2 gr increments, not really expecting to make it all the way to 44.0 gr before running into pressure signs. I ended up cutting it off at 42.8 gr due to faint ejector marks. You can only see the marks if the light hits it just right. I was hoping you guys could help me interpret my results and also tell me if I am right for cutting it off there.

I see a pretty obvious node at 41.3 but I really would like a little more velocity than that. I am thinking that 41.9 might be good or possibly 42.3. I had primer cratering throughout, even on the factory loaded 143 gr ELD-X which got me 2579 FPS. (Pic attached) I ran it through first to make sure the chronograph was working. I also noticed what seems to be some primer flattening even at 41.0 but it did not seem to get worse up to 42.8 where I stopped. The second pic attached it the 42.8 gr case. What do you think?

Factory 143gr ELD-X143 gr ELD-X w/ 42.8 gr H435042.3gr is your upper node. If you want more velocity with that barrel length you’ll have to try RL16 and see what that does for you.
Ive got some RL16 on the way. Excited to see how it compares. In the mean time though I’ll load up some 42.3 and see how they group. Thanks for the input!
Is an ES of 1 at the lower node that is only shooting 2662 FPS better than an ES of 6 at 2730 FPS?
I’m just wondering, at what distance would you have to be shooting for that ~70 FPS gain to be worth the higher ES when using a heavier bullet in the 140-147 range. Just curious everyone’s thoughts since I rarely get to go past 600 yds.

If you’re only going out to 600 yards just shoot the lower node. To me that 70 FPS would only matter if I was shooting comps or shooting past were my load was going subsonic
I'm new to reloading 6.5CM, and would like to hear opinions about large v. small primer brass. I'll be buying all new components, and would like to start as I intend to go on. I would prefer to use small primer because I already load with those, but if the large have an advantage I'm willing to keep both on the shelf.
It seems like the answer I see the most is that it allows you to use Lapua brass who does not make Creedmoor brass with a large primer pocket.
I fought this battle myself recently. I ended up going with small rifle primers. From everything I saw there is no right or wrong answer.
From an accuracy standpoint there is a little bit of conflicting reports which one is better. In the end small rifle maybe marginally more accurate because there is more consistent ignition and burn of small rifle primers which may give you a tighter standard divation. On the flip side it appears you may lose a slight bit of velocity with small vs large.
The big selling point to me on the small rifle primers was brass life. Small rifle primer pockets will last longer.
Then lastly I was like well if Lapua only makes 6.5 small rifle primer it must the better of the two.
The only real potiental con I see is possibly cratering and priecing the small rifle primer with a large firing pin. I don’t think this is as common as I originally thought. In the end you can always Bush your firing pin.
Hope this helps! I just got all my 6.5 reloading gear last week. Next weekend I am swapping my 308 barrel with a 6.5 and headed to the range.
OK, what the heck is going on here? I loaded up a ladder of H4350 under some 147gr ELD-M's in Hornady brass, using a FGGM primer. Why are my velocities so low?
Getting up towards the top, I noticed some slight cratering around the primers, but no ejector wipes or anything of that sort. I was using a Magnetospeed V3, shooting through my can. Last time I was out shooting these loads, I was seeing velocities in the 2670fps range from 40 or so grains of the same powder out of the same jug..
Im so confused.

What barrel length? Also, what chrono are you using? Is the Chrono proven reliable or calibrated? Confirmed with dope?
The barrel length is 24", as stated, used my Magnetospeed V3 which has been proven to be accurate in the past, confirmed with DOPE.
Something has to be off there. I can’t imagine it’s that slow. I’m at 2780 with 42 gr of H4350, 143 eld-x, and a 24” benchmark. Used my MS sporter for speed.

Alpha brass has significantly less capacity than Hornady. I went up to 42.2gr and got over 2800fps, but worried about pressure signs in the summertime 90's temps. OT was also starting to crunch powder at 40.5gr.
Overall I'm very happy with the brass. SD's dropped to under 10 immediately, and accuracy went up. Hoping to get way more reloads as well.
