Re: 1 in 9.25 Twist Capable of Stabalizing 115 DTac's?
I shoot a 243 win Rem 700 with 26 inch barrel and 9.25 twist. I shoot 100's, 105, & 107 It has done some single hole 100 yards and some touching clover leafs at 200 Using @ 46 grains of R-22 or @44 grains of Hodg h100V
My scope has 1/8th inch clicks and you can literally walk the holes across the paper to zero it in.
Mathmatically 105 should be 8.5 to 9. but increased velocity helps with a slower twist.
