140 eldm h4350 load data help please

[Peebles24]

I do not have a book recent enough to have this pill in it and i need to start working up a load for competition. I have read many people say that 41.5 gr is the basic load, but would like a little more accurate info.

My rifle is a bone stock savage 12 lrp in 6.5 creedmoor. I will be starting work up at 20k off lands seating depth. After finding a node i plan to adjust seating depth.

Any screen shot of load manual data would be perfect. I gotta get the new hornady manual ordered but first match i want to attend is the 27th of this month.

Thank you all very much in advance.

It is either Hornady or Hodgdon that has loading data available on their website. lg

I checked hornady and hogdons site. Hornady had info for 147 eldm and hogdon had data for 140 amax.

 

[Peebles24]

Say load data says max for h4350 is 41.5 gr at 2.8"oal, if my oal is longer to be at 20k off land is 41.5 still max? I know this is a noob question but changing oal changes case capacity which should effect max charge and i dont want to screw up.

Only you can know this by carefully working up. If your Savage is short throated like mine you'll be hitting max load before Hodgdon data

1st, 40.9 is max for h4350, imr 4350 is 41.5.
2nd be careful, if exceeding max charge.
I would load 3 each moving up in .1gr increments watching for preasure signs.
Shoot for groups or ladder, which ever you prefer.

The 10th edition hornady manual (I found the newest info) says h4350 35.6 to 41.5. I planned to start at 38 gr.and work in .3 increments looking for a node. I wish i could post pics from my phone. I have never loaded over book max before it scares me so i doubt i do. If i did i would definitely go in .1 increments.

I used to have almost 20 screen shots of people’s loads from SH reloading depot forum and this page and they were all 41.5-43.3 with the majority closer to one end or the other.

I use IMR 4451 and H4350 interchangeably. I get a little more velocity with the IMR but my load on both is 42.2. The 140g ELD is (in my gun not yours) 2.245 to lands. I'm at 2.225 CBTO.

I'm not sure on COAL off the top of my head but they don't fit in regular mags. Needed to get the magpul 7.62 AC which fits up to 2.86.

As always work up slowly...

I have that same rifle as you and can save you some bullets and time, start closer to 39.5 grains and work up from there. Those 140gr ELD's like the speed and likely you'll end up somewhere over max. I'm at that threshold now with my loads. I found that starting low and working up you'll likely find a couple of "accuracy nodes" and the lower one wont really have the velocity needed for long range. Now when I'm trying a new powder I start in the middle or slightly higher and go up from there, just watch for pressure signs and be safe.

It all depends on what brass you are using. Case capacities fluctuate between 49 to 54 grains of water depending on whose brass you are using. One of the Creedmoor's problems is to hot loads wreaking brass. Be careful and start low.

What kind of distance off the lands does your rifle like?

What kind of distance off the lands does your rifle like?

.020 in "my" rifle the 140gr ELD-match is on the lands at 2.230 so I tried 3 each with a know decent shooting load at... touching, .005 off, .010 off, .015 off, .020 off, .025 off at 100 yds. and the .020 held the tightest group so I load all at that distance. This is all measured using a Hornady comparator and the bullet depth gauge. I did not go through with the hassle of sending in a fired piece of brass since I measured the purchased threaded case against my measurements and they are within .0015 difference. Close enough for me.
Will give you a heads up, I'm getting superior results with IMR 4451 powder in my 6.5 using the same bullet. 41.0 grains .020 jump, velocity of 2680fps. Shot this 4 shot group at 100yds tonight, thought I was missing the cardboard completely till we walked down.

Damn nice. I was going to start at .020 off lands. I have the hornady oal gauge and brass also. I am planning to find my base to ogive measurements tomorrow. Was contemplating running the threaded brass through my whidden sizing die without the bushing then trimming to my length. Should i?
I have h4350 i bought at a really good price. I hope my gun likes it. Would love to shoot some one ragged hole groups.

What charge and speed was best for your rifle with 4350?

Measure that case to compare it's size to one of your fired brass AND one that has been resized. The Hornady "tool brass" needs to be close to your fired brass. I would not resize it unless it's just too big and trimming is just not needed. Another test for it is to try it with the bolt to make sure it will chamber.
I have quit with the H4350 powder but my last loads with it was 41.8 and that is slightly above max. Don't just try it, every gun is different work up.
I might try a Satterlee load test with the H4350 now that I have my chronograph just to see where the accuracy falls. Funny, my old way of testing was 4 shot groups at different charge weights to see which groups the tightest and they almost match exactly with the Satterlee results.

Ok loaded my work up rounds this morning. Found my OAL and set all at .020 of lands. Loaded 3 each starting at 39.0 to 41.1 in .3 increments +/- .01gr then loaded 3 each at 41.3 and 41.5. I hope this gives me a good place to start. Now for finding a node i plan to shoot at 200 yard across my chrono recording each shot and keeping cross hair on a dot, then i am looking for the group that has the highest point of impact and a steady speed?

After firing 3 foulers on a clean barrel how long should i wait between shots?

Check me make sure im doing nothing wrong before i go start shooting please.

Side note i am very happy with my whidden dies and hornady lock n load classic press. Total avg runout on bullets is .002. Id say that is good enough or ???

Thank you
Chad

Your highest impact point might just be your fastest load not the most accurate. Shoot for groups and using your chrony find the tightest group and note the speed and load that might just be your winner if it's repeatable. Remember you might find a couple of nodes for accuracy, the fastest one is what you want for distance. I wait 8 minuets between 4 shot groups. .002 runout is not bad but some will say it's horrible. I have not spent much time looking into that just yet but mine are right with yours last time I checked a few.

40.5 gr. Produced the best group by far.
73 degree temp
Little to no breeze
13:00-14:30
200 yard with bald eagle front rest, protector rear bag
Some of the group could have been me i wont deny
Allowed cool down between each group of approximately 5 minutes and about 1 minute between shots.

39.0gr.
1.292" ES 10 avg. 2619
39.3gr.

In the pic i started at top left with 39.0gr. And went down to bottom, right side top is 40.5gr bottom is 41.5gr.

I see zero signs of over pressure on any cases

What should i do next?
