SINCLAIR UN8KP
Uniformly process Large and Small Primer Pockets with a Power Kit
Two carbide uniformers plus screwdriver power adapter for controlled case preparation.
Large + Small in a set

Black-Raptor classification The set bundles the confirmed sizes Large Rifle and Small Rifle/Small Pistol. The adapter saves manual work but does not turn the tool into an automatic: low speed, axial run, and short visual inspection remain decisive for purchase.

Does this fit your project?


Fits well if …
you regularly process both confirmed primer pocket sizes
you have a suitable slow adjustable drive
you need uniformers and power adapter together



Fits less if …
you only want to clean residues or remove military crimps
you want to process Large Pistol or other unconfirmed sizes
you work exclusively by hand and only in one size



What the product practically brings you


Two carbide tools Large Rifle and Small Rifle/Small Pistol each come with the matching uniformer.


Power adapter It connects the controlled drive with the tool and reduces repeated manual turns.


Fixed workflow Same tool choice, guidance, and inspection steps make processing within a batch more traceable.


Limits, disadvantages, and avoiding bad purchases
The UN8KP is not a cleaner, reamer, or swager for military crimps. Large Pistol is not generally confirmed. An electric drive is not included. High speed or side pressure do not improve anything, so
ndern increase the risk of a rough cut or damaged cases.

Frequently asked questions
What sizes does the kit cover? Large Rifle as well as Small Rifle and Small Pistol. Is Large Pistol included? No, this size is not confirmed for this kit. Does it remove military crimps? No. Reamers or swagers with the appropriate approval are intended for that. Is a cordless screwdriver included? No. The power adapter is included, the drive device is not. Why work at low speed? This allows better control of runout and material removal.
Clear purchase decision
Good for reloaders who motorize both confirmed sizes in larger batches. For a single size, manual operation, or crimp removal, a more targeted tool is more sensible.
