the twist is not always exact
I have a sako that is about 1/2" off
as its 1:14.5" rather than 1:14"
add that to a marginal bullet and I went from shooting "bug holes" with 52gr Amax to putting them into the target on a spiral tangent (sideways splash marks, not truly sideways)
pulling the tips changed that completely
with tips:
group size approx 4-7"
without tips, group size 1" (strung as much to do with me whizzing through them to show the holes not the accuracy rather than the load)
52gr Amax vs a 60gr Honady SP that shoots sub 3/4"
Armageddon tipless hollow point Amax!
