Thanks for the info!
Does anyone ever knurl these bullets or is that necessary?
If you can't tell, I'm a total novice with sabots. I do have some 300gr XTPs in .452 and some black sabots I bought a while back. Is there any way to identify the sabots because I have no idea what brand, etc. Maybe measure the petal thickness and length?
I tried shooting them with T7 pellets a few years ago but didn't get good results. I am realizing now I will just have to try a few different components and they could shoot well after all.
