I lived near Martinsburg WV and we had three roads called Flat cat Lane, Flat Rabbit Rd, and Flat Squirrel rd. Either nobody had brakes or really stupid critters that lounged on the roads.
Out of all the different ammo I shoot the rem golden bullet belongs in the golden toilet. My SR-22 handles most everything but the golden bullets have a higher FTF/FTE than anything else I tried. It also groups poorly too. I have some old PMC match 22 ammo that outshoots everything out there in my sR and my 10/22's. Don't know where to get the stuff anymore in Canada now.
I have an extremely accurate lab scale (measures 10,000/gram) which I use to sort my federal bulk ammunition into 3 groups of weights. I know its tedious and time consuming but I do it while watching tV. It makes a huge difference in consistancy and and as long as I use ammo from the same weight group, IMHO, it shoots darn near the same consistancy as some of the match grade stuff out there that costs 3 times as much. When I really want to narrow it down more, I measure the rim thickness and sort out the weight groups even further. The ammo then gets put back in the clear plastic holders that keep them properly separated and they are marked as to what weight group they fall in.
