SlugMaster

Full swaging control on your arbor press — no dedicated press required.

 

The SlugMaster delivers the capabilities of a dedicated swaging press in a kit that runs on a standard arbor press. It's our patent-pending answer for the shooter who wants a press's adjustability without a press's cost.

 

What it does. Adjust slug weight, set hollow-point depth, and form true boat tails — all from a single die, without buying a separate insert for every weight.

 

How it's built. A closed die with side bleed holes (auto-bleed — no trimming). An adjustable nut on the guide sets slug length and weight. A depth-adjustable pin holder locks hollow-point depth precisely. It uses the same Freedom V3 punches and pins as the Freedom Press, so your tooling carries forward if you upgrade later.

 

The honest trade-off. Like any hand-assembled kit, you reset the parts for each slug, so it's slower than a dedicated press. In exchange you get full adjustability — weight, nose, and base — in one compact kit at a fraction of the cost.

 

Calibers: .177 to .30.

Who it's for: experienced shooters who want maximum versatility from one kit, and who value adjustability over raw speed.

Note: These are tools and will require a hydraulic press system to use them.

    Exceptional

    I have tried many Swaging kits of all price ranges and these are 2nd too none and are easily on par if not better than the top tier. The slugs they produce and the ease in which it can be done is exceptional. I have just ordered a custom .253 for my slugmater press kits and I am confident that the product I recieve will match if not exceed expectations

    Slugmaster - perfect DIY kit

    The slugmaster I've found not only to be a very high quality product, but one of the most versitile kits out there, especially aimed at the DIY market.


    The product is amazingly high quality with great machining, best out there.


    This is all supported by a great customer service approach and a company who really are focused on driving the industry and also working with the user to continually develop. I will not be going anywhere else.
