Some makers already supply some lines that have undergone more thorough sorting / QC / weight and uniformity checks, I believe......

JSB do a selected line of .177 Exacts. The name escapes me now. And don't H&N (and possibly RWS) also do lines of finely sorted and checked & individually separated match pellets in those little trays?

Anyone remember the Gunpell Clones from the late 80s? I can't remember which varieties they marketed (maybe the Superdome and FTT only?), but I still have some of the Superdomes in their sealed trays and boxes. These were supposedly closely inspected and weighed. Don't know if they were sized or size checked (probably the latter?) and if they were washed & lubed?
