Savage 243 and 103 eld-x

[obsessed1]

So I have been playing with the 103 eldx in my savage 11 9.25 twist. I have been using imr 7977 and have velocities up around 3000 fps with no signs of pressure. Unfortunately running up and down in .5 grain increments my best results have produced 1.5" groups. Switched to h4831 and started off around 41 gr and worked up to 43.5 groups got noticeably bigger as velocity increased. My 41 and 41.5 gr groups both were between 1/2 and 3/4 inch but my 43.5 groups opened up closer to 2". Unfortunately the groups with promise are around 2700 fps well short of my hoped for 29-3000. I'm really hoping to get this rifle bullet combo working but I don't have any other suitable powders in the gun room so I'll have to buy something. I'm hoping not to buy a lb and find it's useless as well..any one have a fave load using this bullet in a 9.25 twist that's accurate at the higher velocities? I'm not against trying something different but I'd like to cut the search down as much as I can. I'm thinking retumbo or h1000 maybe. It seems strange to me that this gun likes this weight at the slower velocities I figured because the twist is on the edge of being fast enough out would do better being pushed faster.

Have you tryed playing with the coal I have found them to be a little sensitive to seating depth

[obsessed1]

I tried seating them as long as possible in the mag ( no where near the lands....) then ended trying a min col of 2.850. This is where the light loads of 4831 shot great. Typically I'll work up a load in .5 gr increments to get find a node then refine by .1 increments to refine accuracy further. Then if I'm in the velocity range in looking for and accuracy is acceptable I'll play with seating depth to wring out the full accuracy potential. So far though I haven't gotten anywhere close to accurate near my desired velocity.

Give Hodgdon Hybrid 100 V a try. Somewhere around 42.00 grs should get you to 3000 MV

Interesting article

“I can get the exact same great results in a velocity node using seven different powders. As long as I keep the bullet going the same velocity from powder to powder I get the same result.

Good article. but the method is very close to OCW.
I just wanna know his secret..

"Next I then load up 5 of the 51.5 grain load and shoot them over the chronograph and the extreme spread was 5 FPS. I have repeated this with H100V, H4350, 4831, 1000, Retumbo, RE 17,19, 22, 23, 26, wiN 760, 780, VV 160, 170, 560, 570 IMR 4451, 4955, 7828 and 7977. With all of these powders, 3020-3035 fps was an accuracy node without regard to the powder type.

I think he must have been referring to Std Deviation .Still dang good if he's getting that SD with all those different powders and a 15 fps Max spread on the node. Not a skeptic, but..

I have tried that method before for some rifles it worked well with the powder of choice...did not test with other powders to see if the results were the same though.

From my experience, it can't be done, but I've been wrong before. Still would like to see it .

He was getting an es of 5 so an sd of something like 2 or 3
I’ve used this method on a few rifles it works
If you cant get accuracy but you have the consistent velocity’s
I swap bullets

Awesome results. What I don't get, is how he gets the exact same results with the same charge weight from a variety of powders that have varying burn rates and load densities. What would swapping bullets do? Maybe I missed something.

[marky_mark]

I don’t think they are the same charge weights
I think it’s When he gets the same velocity with different powders usually that’s an accuracy node

Ok..I didn't read it right. He loads each to the exactly the same velocity with the different powders. I can see where that might work. Thanks
