I currently use the 12ga Hornady SST in a Marlin 512 1:28 twist, sighted in for zero at 150yrds. The SST is a 500 mag 300gr FTX bullet at 2,000 fps. "The SST Shotgun Slug delivers true 200 yard accuracy and you'll achieve sub-2" groups at 100 yards. No other slug gun ammo can come close to the performance of the SST. The sharp point increases the ballistic coefficient of the FTX, allowing it to fly faster, farther and on a flatter trajectory."
I first thought I would cast a bullet for a sabot wad. I never figured out what wad/bullet combo would meet my needs.
I've been following all of you casting heavy 12ga slugs 500gr-800gr these all seem to work well but are pretty heavy.
The wadcutter pellet mould is about 525gr and flat, cast in zinc it would be about 315gr but how well will it fly to 150yrds with that large meplat?
I'm looking for a slug combo at around 300gr. Either sabot, inside a wad, screwed on wad or pressure wad.
I'm thinking of getting one of the Russian hydrant moulds and casting with zinc wheel weight alloy. Zinc would put this slug at about 315gr. plus the tail wad. I for see availability concerns.
A buckhammer type slug might also do the trick cast in zinc.
I realize these won't expand but do they really need to?
I have two 512's and would dedicate one to shooting these. They both have Nikon BDC scopes. I'm looking for accuracy and a good amount of distance as I can shoot my Rem 1100 smoothbore 100yrds without issue with foster slugs.
I have plenty of SST's and don't really have time to hunt so this is more a just because I want to project. But I'd love to find an accurate replacement for the SST's.
We also recently got a Savage 220 and are looking for some good slug/wad combo's for that as well. I'm also thinking of casting a zinc slug for a sabot for that as well. Most of my friends now have the 220 and ammo is hard to come by here, especially the Remington 20ga Accu-Tips.
What's been working for you, let me know. Thanks, Jason
