The Superior Shooting Systems Tubb Seating Die is out of stock at every supplier we deal with. These are in stock or available to order now.
The Superior Shooting Systems Tubb Seating Die is a bullet-seating die with a micrometer fine-adjustment and a removable seating stem sized for heavy bullets. It lets you set seating depth precisely using the numbered micrometer ring while coarse position is set with the wing nut and screw.
- Seating stem options: use the stem with the larger internal diameter when seating 250‑grain bullets or heavier.
- Coarse vs fine adjustment: the wing nut and screw provide coarse positioning and are typically backed out fully; the numbered micrometer ring is used for precise seating-depth changes.
- Setup guidance based on die mechanics: insert an empty case, run the ram to full travel, screw the die in until it seats then back out 2–3 turns (more if proximity issues occur) before trying a bullet; adjust seating depth with the micrometer.
- Bullet diameter effect: larger-diameter bullets (for example 37XC or 41XC vs 33XC) require moving the seating-die threads farther out; this does not reduce the die’s accuracy.
These features focus the die on controlled, repeatable seating depth with both coarse and micro adjustments to suit heavier and larger-diameter bullets.
