Long Distance Load Tuning
I have found a good load for my new Tikka SS 25-06.
52.0 gr IMR 4831, Berger 115, Fed 210, seated to touch, neck and bullet runout less than .002 ave. Velocity = 3040
Four initial groups at .90, .55, .44, and .25. The first of the string included a first shot, cold bore, fouling shot that was approx .40 from the other shots.
Now when I take this load out to 200 yards, my groups have been 1.60 1.90 and 2.1.
It may be me, but so far it seems that the groups are opening up. As I test at longer ranges, are their tricks anyone has found to tune. I already went through some seating and primer tests, but should I redo them at longer ranges?
