Thks so much for the info, was hoping you would chime in. Do you think 2900fps is a realistic expectation with these out of a 28 inch 4 groove Bartlein?
I've got a 5r in the same barrel In sendero contour, I'll just save the 4 groove for my old 06 when it's ready. Thks for the advise! Really appreciate the help fellas.
