I'm fine with lead free options.I think for lead it's the RWS Hobbies.
These ones Motorhead?There have been some plastic outer / sabot cored hybrids made by SKENCO that ran about 4 grains or so.
Made In Hungary, tho no idea if or not there still available ?
They look very strange. How well do they shoot? What speed do they shoot? Co2 speeds? Specialized ammo for Co2s? Bueller? Bueller?They had @ 4 versions as I recall. The sabot style / weight changed with differing designs they offered.
Those are sorta similar, but the skirt tail / sealing band of those shown above are different.
The SKENCO offering looked a lot better quality wise having no obvious parting line / cast / extrusion artifacts.
Here are some for reference:
These are .22's FYI
Red = 18 grain
Green = 10.4 grain
