Group Analytics / General Guidance for new Load Developer
5:23 AM
I am trying to figure out the best powder loads for my rifle. I have read some content online that I found downright confusing; for example the OME method = obhective is not to shoot the tighest groups? Anyone who can explain this would be a huge help, or reloading/load development tips in general.
Other questions:
- What can I learn from:
----Vertical spread?
---- Horizontal Spread?
Special formulas they care to share?
I am running a 6.5 CM:
- Berger Hybrid Target Match 140's
- IMR 4350
- CCI 200 primers
Thus far I have shot about 25 reloads. I have been using an OCL of 2.8 (per hornady handbook and the length of ELD-M 140's which my gun shoots very well). My best (highest) groups have been using 40.8-41.5gr of powder (Hornady's max is 41.5gr)
On a side note, once I get the powder load figured out I am going to work on seating depth. As I said I have been using a OAL of 2.8, but I have a Forster Micrometer Seating Die I am really looking forward to learning how to use.
Thanks
