Nice rifle you've got there 303. I have the twin to Klik's laminated 7-08 that is just sitting in the corner of the safe waiting on a new McM handle. So far its looking like R15 is the powder for mine. H414 was horrible accuracy wise. I'll also be trying some Varget, CFE223, and BL-C2 with 120gr. TTSX
