I Had a range session last weekend fired 59 rds of 140gr Amax though the Sako 6.5x55.
I neck sized, chamfered etc this morning then looking over the targets again and still not being too happy with the accuracy results thought I might as well resize and have all back to spec for the next time.
The lapua brass for this batch would now be on it's 5th firing next out of the barrel.
So I proceeded to F/Length size, chamfer in and out again then on a whim got the Calipers out..., guessed right huh.
Yes, as I write this I am about half way through hand trimming these cases.
Now I know ... again,, why I neck size only until I absolutely have to go F/L.
Never mind, sigh, has wasted a perfectly good day here in the South of New Zealand.
