Kontareva-3 Russian 12ga slug mold.........

[longbow]

According to the website the slug should cast at about 0.728" and weighs just under 1 1/4 oz.

It is a nice looking mould and slug!

With those deep grooves I'd guess the driving bands would swage down quite easily of the slug was oversize. I wonder how well it would knurl? There should be enough band there. My knurler takes my 0.729" as cast slugs up to ~ 0.735"

I'll be looking forward to range reports on this one.

Good morning
Remember we have been working with undersized molds for years. "Beagle" it or lap it.
I have lapped out numerous Lee molds. Just remember aluminum laps out fast. Metal polish works slower with aluminum. But extra fine grit lap compound will remove the metal fast so be careful.

Mike:

I've knurled some of the Paradox slugs up and they knurl up easy. It is an extra step but not difficult and generally a guy doesn't go through shotgun slugs like .22 rounds. I've as yet to try those knurled up slugs though! Bot to get in gear and get to he range!

Even my ACWW 0.729" turbo slug clones knurl up easy. I made a knurler a few years ago and it works quite well. I also made a 0.733" sizer to suit my fat bored single shot. Not sure how well those will go down my tighter Slugster bore but I have to think it won't be a problem.

Yes, we have suffered from undersize slugs for many years. Make 'em big and let 'em squeeze down! Maybe not with solid heat treated slugs but with ACWW and HB I think we're good to go.

On that note... have you seen the Buckbuster slug group buy in progress? First up is a 0.678" or 0.680" wad slug and hopefully next up is a bore size slug (0.732" I hope). I'm in for the 0.680" wad slug right now. I'd like both wad slug and bore size but if they go with 0.730" not so sure. I guess I could knurl then up a bit. Anyway if you haven't seen it go look at the group buy section and join in!
