I guys I am looking to develop a plinking/50 yard target load for .30-30 with a 165grn RNFP cast bullet! I apologize for asking silly questions like this but, do Red Dot, Green Dot, Blue Dot, Bullseye, 2400, H4227 or unique pose a risk of Secondary Explosive Effect in very light loads? Are they position sensitive? Do you think a squib is much more likely than SEE?
I refer to loads of loads like this Red dot 5.5grns 170grn RNFP .30-30 between 1000 - 1150fps! Green Dot as above 6grns, Blue Dot as above 8.0grns! Bullseye ” 5.5grns 2400 ” 8grns H4227 ” 10grns Unique ” 9grns
I am petrified of SEE!
After a little research into burn rates and density, Blue Dot, 2400, 4227, H4198 and H48955 don't seem so great as subsonic loads!
Where as International, Unique and Universal would appear better suited, but not ideal, having significantly slower burn rates than these powders:
- Alliant Bullseye 9.398
8 Alliant Red Dot 7.077 14 Hodgdon Clays 6.8408 18 Trailboss 3.046 25 Alliant Green Dot 7.924
With the exception of Bullseye, All of these powder are bulky, Trailboss especially so. I find myself thinking that Trailboss and Red Dot, and possibly Clays, are probably the best choices!
Opinions?
