Ok, so I went to walmart yesterday and bought some j thingies to shoot in my new [to me] inline. Now, according to some advice that I got on here, with the sabot, I can shoot .451 rb, for which I have a mold. I checked the j thingy diameter and this will work. What I also found was that 2 rb will fit in the sabot, protruding slightly past the end of the plastic. Now the wheels are turning, I am sure someone has tried this, any reccomendations? Do I need any kind of wad under the sabot or just ram it down on the powder? Wanna shoot this today if weather permits, at least with the j thingies. Thanks in advance.
