Trying to work up a load with the 6.5x284 with h1000 powder and 143 Eldx. What would y'all suggest for the seating depth and how many grains of powder? Thanks.
Consult the Internet and it's always good to have several different reloading manuals to verify information, remember to work your way up don't start near the top. Also is yours a 6.5 x 284 norma or 6.5 x 2 84 Winchester it makes a difference.Trying to work up a load with the 6.5x284 with h1000 powder and 143 Eldx.

You just wont get the speed with 4831SC as you will with H1000 or Retumbo.How bad is bad? If we're talking over 2" groups here I'd change the powder. H4831 is in stock right now.
Hodgdon H4831 Shortcut Smokeless Powder 1 Lb
Hodgdon H4831 Shortcut Smokeless Powder 1 Lb by HODGDON , IMR & WINCHESTERBallistically, this Extreme Extruded powder is the exact copy of H4831. Physically, it has a shorter grain size, therefore, the designation SC or short cut. The shorter, more compact kernels allow the powder to flow...www.midsouthshooterssupply.com
I got 2950 with h4831sc, it's the gold standard powder for the 6.5-284 Norma, which is the sweet spot for the cartridge. I have tried rl26, 23, h1000, h4831sc, retumbo, n560, n565, n570 in the 3 rifles I have had. H4831sc was the most accurate and consistent, retumbo was a very close second. I try and maintain 2950-3000fps with the 143eldx. I seat them .020 off the lands.You just wont get the speed with 4831SC as you will with H1000 or Retumbo.
I had weird pressure spikes with RL26, Retumbo was the most consistent in mine, easily getting 3000fps.I got 2950 with h4831sc, it's the gold standard powder for the 6.5-284 Norma, which is the sweet spot for the cartridge.

Yeah but if the groups print like garbage, doesn't matter how fast you send the bullet on its way to missing. That's why I qualified with the group being over 2", that's indicative of a component mismatch. We can all want the speed as much as we want, but if it doesn't print it doesn't print.You just wont get the speed with 4831SC as you will with H1000 or Retumbo.
It's a secant ogive bullet so the logic behind the Berger test is valid. The problem will come with do you have the throat length/ case capacity to still run enough of the slower powder to pick up velocity if you have to stuff the bullet into the case to get to 0.120" off the lands. My chamber is throated for 156 Bergers so I have enough room to seat deeper, but in a standard spec chamber you might start compressing the load sooner than you want to. No reason to not try it though, just pay attention to load density for the longest jumps if the bullet is below the neck/shoulder junction.Anyone else use Berger seating depth suggestions for 143eldx?
58gr Retumbo/28" Bartlein/ 3060fs was my sweet spot. Saw well over 3100fs but best accuracy was at ssI had weird pressure spikes with RL26, Retumbo was the most consistent in mine, easily getting 3000fps.
Mine has a .199 free bore, and yes if I use the .120 off I'd be compressing quite a bit so I loaded the .010, .050 and .090 off. I'm running 56.5 and .090 of was just a tad bit of compressionYeah but if the groups print like garbage, doesn't matter how fast you send the bullet on its way to missing.
