A note on my Tikka T3 stainless 22" bbl. 260 Rem. Absolutely deadly accurate with any cup & core bullet. Sub 1/2" 3 shot groups. But when trying to work up loads with the Barnes 100gr TTSX, 120gr TSX & Hornady120gr GMX absolute failure. Tried three different powders & shot with bullets seated from .010 to .080 of the lands in .010 increments. . Scattered random 3" to 5" groups. No type of hunting accuracy. Was very disappointed as I liked the rifle very much. Any one have success in their Tikka with the mono copper bullets? My considerably less expensive Savage model 16 stainless 260 shoots these mono bullets into "TINY" little groups. Any suggestions please?
