458 SOCOM: Trail Boss works again
Guys
Posted this yesterday but it hasn't stuck.
Have been working on the 458 SOCOM with 500 and 550 grain loads. Loaded both with 15 grains of Trail Boss.
The 500 grain Hornady RN, as a conventional bullet shape and flat base, sits well on the powder and has room for some more (0.5 to 1 grain) before the powder compresses.
The 550 grain Predator VLD is long and compresses the powder column.
Both shot for group at 50. Both delivered good hunting accuracy of about an inch (big bullets always make the group look bigger) from a slightly wobbly rest. The 550 VLDs put 2 shots in one hole. The 550 VLDs also seem to start tumbling after hitting the target.
No velocities but bullets were subsonic.
