Hello. I tried working up a hunting load for my .243 Sako w/ 87gr xxx....not good. To get decent speeds (cronied each receipe), had to push the envelope. Tried IMR and Hodgdon 4350, 4895 and 4350....bad groups all over the page. Went back to 95 gr noslers and >1/2 groups. Cannot recommend Triple shock. Good luck and regards, Rick.
