Man I am even more confused now. I am on the road now and don't have my manuals, and I don't think TSX's are even in the newer barnes manual. I get frustrated with these damn manuals bc one will have the bullet I like but not the powder or vice versa. And the newer manuals are so conservative. Does anyone know or have the load data for RL 22 with a 180gr TSX???? Also what is the COL? Am I walking a fine line here? Like I said...not one bolt was sticky, no marks on the brass, just flat primers. I will measure the brass when I get home in a week. Gotta love a sales job.
