Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 59250 psi, or 408 MPa
or a maximum loading ratio or filling of 112 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

30 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

Looking at trying H-1000 in the 6.5-284. I have Hornady 143 gr ELD-X (#2635), 142 gr Nosler LRAB (#58922) and Hornady 140 gr SP Interlock (#2630) on hand. LR primers, both magnum and regular, plus WLR which claims to be both by some arcane magic. Lapua, Norma and Nosler brass.

My various trys with H-4831 have shown pressure signs rather below the max levels published, sometimes at or below the lowest published powder weight.

I am working with a 22" barrel, this is the factory barrel on a Savage 111. Not the "long range hunter" or other models with long barrels, the plain jane rifle they sell as a package with a mounted and (allegedly) bore sighted cheap 3-9X scope. That scope is long gone, as is the floppy Tupperware stock Savage sent it out the door with. Rifle is wearing a decent scope and is installed in an aftermarket stock with an aluminum chassis. I have killed 3 deer with it so far, using Barnes 120 TTSX and Hornady 140.

From the above and several other online resources, I conclude one could start the 143 ELD-X at 54 gr of H-1000, possibly working up from there, but not likely to much above 56 gr- Nonwithstanding the Quickloads entry at 59.4 gr above as "near maximum" I would tend to believe others who have tried this and state that 56 is about as high as one should go.

Yes, I know I should be seeking reloading information from "reliable published sources", not anonymous people on web forums. However, I'm not finding the combination in my reloading manuals.
 
You’re probably going to hit max a little faster in the Lapua than the Norma and Nosler.
Might want to check capacity on them.
If you want a little extra zip and don’t mind the expenditure, I’d consider screwing a longer barrel on especially if you’re going to use slower powders.
 
A longer barrel, threaded for a suppressor is on my wish list. A local smith quoted me about $300 for putting on a good quality 8" twist barrel, all in, including threading for suppressor.
 
I have a question about the above data. The OAL listed is quite long; could the 6.5-284 be squeezed into a short action using binderless AICS style mags with the VLD style bullets?

In other words could something like the 140g RDF be effectively loaded to around an OAL of 3.00”?
 
I’m sure you could. It would depend on the reamer you use and the throat. You’d lose a little capacity seating deeper though. May be a little snug. :grin:
