I shot a little this weekend. I think I'm on the right track with a bear creek 300 gr TC and Herco . Unique will remain an option . I got to 8.0 , Herco at 1.61 OAL with much better results than the 350 over h322 . Herco has only become an option in the last couple of years . The 350 with 322 went 1240 with a start load in the carbines but would muster only 600 in the 7.5" BH . I'm hoping the Herco will be different and deliver 850-900 with a 1050 , 1075 fps carbine load .
