I have always wondered if IMR7828SSC would perform well in a 3006 pushing 180gr bullets. I figure that the compressed charges have teh potential to produce good accuracy and respectable velocities while being consistent and having low Extreme spread and Deviation.
Will be doing a ladder test on my loads using 20 rounds 180gr CT BT with Hornady brass and 210 primers, the following is what I will do. Brass coming in today and bullets will be here Monday.
IMR 7828SSC 61.3grs 2785fps with 22" barrel, 60,000 psi and hope to find a sweet spot 2700fps and above, will see.
1. 61.3,
2. 61.0,
3. 60.7,
4. 60.4,
5. 60.1,
6. 59.8,
7. 59.5,
8. 59.2,
9. 58.9,
10. 58.6,
11. 58.3,
12. 58.0,
13. 57.7,
14. 57.4,
15. 57.1,
16. 56.8,
17. 56.5,
18. 56.2,
19. 55.9,
20. 55.6
Note: I will clean my barrel so I can shoot five fouling loads using IMR7828SCC so the barrel settles down and my Ladder test will be more valid or at least consistent.
