FORSTER · Co-Ax Priming Tool · Variant Family
Keep complete bench tool and replacement tubes clearly separate
This family includes either the complete FORSTER Co-Ax primer seating tool for the bench or a single feed tube for Small or Large Primer. The variant choice therefore determines whether you get a usable tool or just a spare part.
Complete Tool · Small Tube · Large Tube

Purchase Check


Fits well
as a complete tool for a fixed, tactile seating station
as a replacement tube only with an existing compatible FORSTER tool
if Small and Large Primers are consistently processed separately



Fits less well
if a complete tool is expected with the tube variant
for mobile use, if a handheld seating tool would be more practical
if damaged or dirty primer pockets are to be seated without preparation



Features and Practical Use


Fixed Bench Tool The complete tool creates a separate seating station and keeps the reloading press free. A stable mounting is part of the setup.


Clear Variant Separation Small and Large feed tubes are individual spare parts. They contain neither lever nor seating mechanism or case holder.


Tactile Seating Process The lever supports controlled feedback. Seating depth and condition of the primer pocket must be checked by the user.


Targeted Spare Part Choice A lost or damaged tube can be replaced appropriately without buying a whole new tool. Size and system must match exactly.


Limits, Disadvantages and Avoiding Wrong Purchases
The most common wrong purchase is the cheap replacement tube expecting the complete tool. Check scope of delivery and primer size before ordering. The tool does not correct deformed, dirty or improperly prepared primer pockets and does not detect incorrect seating depth.
Technical Data
with practical sequence


Variants Complete device, Small Tube or Large Tube; practical sequence: selection determines the entire scope of delivery.

Mounting Bench device fixed on a stable surface; practical sequence: reproducible working position.

Application manual primer seating; practical sequence: check each case individually.

System FORSTER Co-Ax Bench Priming Tool; practical sequence: do not assume replacement tubes are universal.

Scope of delivery
Depending on the chosen variant, either a complete FORSTER Co-Ax Bench Priming Tool or exactly one replacement feed tube for Small or Large Primer. Primers, cases, bench mounting, and other spare parts are not automatically included.
Application, safety and care

Check variant and primer size again before opening or installation.
Secure bench device firmly, wear safety glasses, and remove powder from the workspace.
Use only clean, undamaged cases and the correct primer size.
Stop immediately if there is unusual resistance; do not force the seating movement.
Keep feed tubes clean, dry, and undamaged; replace damaged tubes.

Frequently asked questions
What does the "Complete device" variant include? The complete Co-Ax bench priming tool, not just a tube. What do "Small Tube" or "Large Tube" include? Each only one replacement feed tube of the chosen size. Can a replacement tube alone seat primers? No. The compatible complete device is required for that. Is the tool mobile? The bench device is intended for a fixed working position; a hand priming tool is often more practical for mobility. Does it measure seating depth automatically? No. Case, pocket, primer, and result must be checked.

Black-Raptor classification The complete Co-Ax device is a clean separate seating station; the tube variants are pure spare parts. Choosing the variant correctly avoids the main wrong purchase in this family.
