Hi Guys,
I need help trying to find a load for Hornady 178Gr ELD-M bullets.
I can't these things to shoot at all.
Rifle:
Big Horn Origin Action
Criterion 24" heavy barrel
KRG Bravo Chassis
Using a Magnetospeed (Yes, Labradar is on its way even though the Magnetospeed has worked fine)
What I have tried: (5 shots groups)
All rounds were COAL of 2.805 (Mag fed) using LC 1x fired brass with CCI LRP
IMR4064: 42.0 - AVG: 2696 - Grp: 2.25" SD: 37, ES 53
IMR4064: 42.3 - AVG: 2685 - Grp: 1.75" (Slower??) SD: 7, ES 17
Shooters World Precision: 41.8 - AVG: 2608 - Grp: 1.937", SD: 9, ES 21
Shooters World Precision: 42.0 - AVG: 2632 - Grp: 2.0", SD: 21, ES 45
Shooters World Precision: 42.2 - AVG: 2638 - Grp: 1.0", SD: 17, ES 47
Shooters World Precision: 42.4 - AVG: 2662 - Grp: 1.25", SD: 7, ES 18
Varget: 41.8 - AVG: 2670 - Grp: 1.5", SD: 29, ES 72
Varget: 42.0 - AVG: 2660 - Grp: 1.75", SD: 17, ES 46
Varget: 42.2 - AVG: 2676 - Grp: 2.0", SD: 13, ES 35
Varget: 42.4 - AVG: 2693 - Grp: 1.75", SD: 14, ES 33
All rounds seem to have the SD and ES all over the place.
Just as an FYI. After all the rounds (50 Total), not being happy, I decided to take a few shots with my other known good round.
175SMK with 44.1 gr of Shooters World Precision @2.80"
5 shot average of 2758fps with SD 7 and ES 17 group of 0.7". Previous week was probably a 0.4" group but I did not out there checking. Just shooting for fun. I was out there trying to find a load for my Creedmoor. Actually using 147 ELD-M. Much better in that rifle. Groups of 0.4".
Anyway, I then took 3 shots at a 300 yard gong. all 3 in the center with an average of 2750fps SD 3, ES 7.
The rifle can shoot. Just for some reason it seems the rifle does not like the 178 ELD-M. Will be trying Bergers next or probably just stick with the 175 SMKs.
Any help will be greatly appreciated!!!
