Quickload load help, please?

[hboothe]

I have a bolt action I chambered (yes, I did the lathe work) in 6.5 BPC which is just a 6.5 Grendel with slightly modified chamber specs. I throated it long so I could use extra heavy-for-cartridge 147 Hornady ELD-M. But there's no load data for such a pairing. I started with Leverevolution because I've had good luck with the lighter bullets in an AR but my only "feedback" for over pressure is reading the primer. Not ideal.

Normally I only load book loads (Nosler, Hornady, Hodgdon, etc.) Trying Leverevolution in any Grendel load was "stepping off the reservation" for me. I don't normally do this kind of reloading or I'd buy QL and figure it out. But, for one cartridge/load the learning curve isn't worth it.

Can someone do a load workup with QL for a 6.5 Grendel with 147 Hdy ELD-M at a COL of 2.553", please? The bullet seats about 0.264 into the neck, keeping the bearing surface above the neck/shoulder junction. I have a variety of small rifle primers. For powder, I have a pretty good variety from Hodgdon/IMR plus I have TAC and RL15, PP 2000-MR, RL-17. I'm am okay with buying something if it is better suited to this bullet/case size combo.

Thank you.

First, I'd like to recommend that if you don't want to buy a copy of QuickLoad then check out "Gordons Reloading Tool" at GRTools.de - this is a free interior ballistics program that is *SIMILAR* to QuickLoad but does not have all the same powder profiles that Quickload does - updated versions are released quarterly. I have been using both side-by-side (yes, I'm a geek) and have some confidence in the loading solutions.
Note that this data below uses the case capacity of MY Hornady brass in MY rifle with YOUR requested COL AND MAX CHARGE limited to 56k psi (lower than CIP). I've also purged the loads that were over 101% fill and powders that aren't in the U.S. (Ramshot Wild Boar). The Lovex powders are sold under the "Shooters World" label at MidSouth, Grafs, and others.
