View Full Version : Lyman sabot slug vs. Lyman F oster slug accuracy?

Has anyone done any accuracy testing in a 12 guage smooth bore between a Lyman sabot slug and a Lyman Foster slug?
If so, what were your results?

Lyman Foster slug from my blocks was WAY undersize. It would literally FALL through the bore and out the modified choke tube of my Win-choke barrel. Accuracy was very poor in rifled OR smoothbore barrels - like Minute of 5 gallon Bucket @ 75 yards. Lyman sabot slugs from my friend's mould ran much better - like Minute of Paper plate at 75 yards. We only tried a few different loads with those - there's probably some room for improvement. Still not as good as Winchester factory foster loads will shoot for me in smooth bore OR rifled barrel. Wanting to shoot the BCBC at Second Chance, my friend and I worked up a load many years ago with a .690 round ball in the shot cup of an RXP wad that does much better in my rifled Hastings barrel than either of the Lyman slugs. Makes durn near raggedy holes at 50 yards - opens to maybe 5" or so at 75 and corkscrews out to paper plate groups or worse at 100. On 75 yard bowling pins it was pretty reliable - would hit probably 9 for 10.
If the two Lymans are your options, I'd go for the sabot slug. I have to admit I haven't got it all figured out yet - I would love to come up with a mild-kicking 2-3 MOA 100 yard load for that Hastings barrel.

I get really good groups out to 70 yards or so with the Lyman Sabot through a smoothbore. 3-5" is the norm, but considering each hole in the target is almost 3/4" that's a pretty tight group. With a rifled choke the groups tighten up considerably at short ranges, but I have only done better than 7" at 100 yards a few times. Awhile back I posted a 4 5/8" 100 yd group, but so far that is the best I've done using open sights.

Comparing accuracy between the two slugs molds you have mentioned as they come from the factory is like putting a "Pre-Jesus" George Foreman in the ring with a modern day stupid white high school gang-banger punk who talks **** about people with other skin colors and who thinks he is tough. "Pre-Jesus" George Foreman wins the fight in question with a nock out in the first round.
You need to have the Lyman foster mold spun out to full bore size on a lathe before it can even hope to have a fighting chance against the Lyman 525 overgrown air gun pellet wad-slug, and even then it's and underdog in the competition. The nose shape needs fixed and the skirt is too thin as well. Heck by the time your done with all that modification to the mold your just better off if you had a custom one cut right from the beginning.

Thanks fellas for the information. At least, when I decide to buy a mould, it will be the Lyman sabot mould.
I tried some more round ball loads this last weekend. So far the groups stink. I will try some more later this week.

If I were you I would first put the round ball or slug in a wad with different thickness of petals and try pushing it through your barrel with a cleaning rod or wooden dowel and find the right combo that slides through with a little push. Now this combo will work better in your gun when loaded properly for accuracy. Going out and shooting different slugs without doing your home work makes no sence and just a waste of money.
Here's the secret: Accuracy from a shotgun slug is a function of two things:
1. A good gas seal.
2. Centering the slug or round ball in the bore.
Achieve those two and you can shoot as well as many.......
Hope it helps
