Svarog Paradox Slug Mould

Svarog Paradox Slug Mould

Late last year I wrote about the Russian ‘Zveroboy’ slug mould by Svarog.  As Winter tends to be my reloading season, I thought it might be interesting to review another one I’ve been working with a lot lately; the Paradox.


Like the other Svarog models I’ve seen, the Paradox is a single-cavity aluminum design made featuring cylindrical blocks and an included set of handles. Once again the Paradox makes use of Svarog’s press-fit spherical alignment pin system, and a stamped alloy sprue plate.

The Paradox includes a standard hollow base pin, although the manufacturer now offers several other styles including one for the Gualandi-style stabilizer slug wads.

As with the other Svarog moulds, the external machining on the blocks is a bit rougher than I’d like, although the cavity itself is flawless.  It’s always nice when your tools look first-class, but as this completed mould can be had for less than Lyman charges just for a set of blocks; it’s pretty hard to complain.

With all that said and done, let’s take a look at this thing in action.


To prep this mould I started by giving it a bit of a spray with some automotive carburetor cleaner. This just helps to clear away any dust or residual cutting lubricant that may have been left behind from the manufacturing process. Likewise I added a dab of oil to the hinges and sprue plate to make sure they move well.


Being an aluminum design, the Paradox is extremely lightweight and easy to handle. It also heats up quickly, which is essential to getting good fill with a pin’d system like this. As with other Svarog models, the sprue plate’s edge is fairly dull, leading to rougher cuts. I’ve since sharpened mine up, and I’d advise you to do the same.  It only takes a few minutes, and ultimately your finished slugs will come out looking much more consistent and flush.

One of the things I really like about the Paradox is just how easy it is to extract the slugs after casting relative to other pinned moulds I’ve used in the past.  Once the mould is warm enough, the slugs practically fall out on their own, without any of the issues with binding to the pin.  It may not sound like a big deal, but this makes a massive difference in production.

Paradox Slug

Like all my slugs and buckshot, I chose to tumble these in some walnut media to smooth out the sprue cuts and mould lines. As you can plainly see, the finished product looks great, with very consistent moulding and full retention of fine detail.

The slug itself is fascinating; in many ways not unlike the famous Foster design most of us grew up shooting.  It retains the classic hollow-based dome shape, but employs three rings to reduce the bearing surface (and thus friction), ostensibly increasing velocity.  These rings also serve to strengthen and reinforce the slug.

Dimensionaly the Paradox is an absolute beast. At nearly 3/4″ in diameter, it weighs close to 1.5 ounces, packing an incredible amount of punch at firing. To put that into context for you, in the video above you’ll see a comparison with a Lyman sabot slug– which I used to think of as a large projectile.  Because of their size, Paradox slugs can’t be loaded in a standard shotshell wad-cup. Instead, you’ll need to use a buckshot/slug wad or gas seal such as the Russian Buckshot/Slug wads, or BPI’s BW12 & FS12 wads.

As all three of these wad styles are fairly low profile, you’ll find yourself staring at a fairly short shot column.  That makes these slugs ideal for short hulls like 2 1/2″ (or the now very much in-vogue super-shorties).  Likewise these slugs also provide savvy reloaders with an opportunity to get one or two more uses out of old hulls by trimming down worn out 2 3/4 and 3″ hulls.  If you’re a traditionalist who insists upon standard 2 3/4″ or 3″ shells (or your gun simply won’t cycle anything shorter), you can still easily load Paradox slugs by using full-sized wads such as the 1/4″ cork disk shown in the video above.  Cushion, filler and full-sized wads like these make it a snap to raise your shot column to a desired height without having to compromise.
