Hell my Lis. plate on my Jeep reads 22HPsav, a bit off corse I have never seen an AD for the 22Hps, a lot of the savage ads say High Power but it seems to always be for the 2503000, Im likeing the one on Ebay with the 303 and the Tiger tho!
I have never tried a 224 bullet in the Hps like the 228s just fine!
