So Daisy fooled me -- I did not know they had more than one type of "Match Grade" BBs available. I thought I was ordering the "Avanti" 1050 BBs that are ~0.175. Instead I got the red/yellow labeled ones, which say they are 0.1720 caliber. I did not know these existed.Had I looked closer when purchasing, I would have seen the size listed -- but I thought a tub of 1050 BBs was only an Avanti thing, so I did not bother to look closer. So technically, my fault. My Model 35 shoots everything almost equally bad, so no comment on yay or nay on these. I'll do a closer study of size, roundness, weight of these at some point.
