They are a .40 cal ,thats why the sabot is so thick.
Have been shooting the SW and sst in my 50 cal encore since they came out.
If you check the pic in my post ("encore barrel changing ") you can see how they shoot for me.
Tried to get them to shoot in a 45 cal barrel with no luck at all.
Was shooting the 195 barnes in my 50 cal before the sst and SW came out but they didn't work to good on a big 8 pointer but the sst and shock wave is one heck of a deer bullet in either 200,250 or 300 gr.
