Sako A7 Accuracy?? 300WSM
I got Sako Tecomate a few weeks ago and recently shot it with some hopeful but interesting results. The first week I shot it, it grouped poorly, 2 to 3 inches. I broke in the barrel and cleaned after every three shots, but it was in Nevada so it was hot. I noticed, later in the day, when I started doing 5 shots between cleaning, that it shot better fouled with a couple of rounds and hot? That was a little strange.
Next week, I shot again. But before I checked the stock and it seemed like the Hulk tightened the stock (60 lbs)! I loosened it and tightened it back up, once I felt the resistance, I gave it a 1/4 more turn (about 35lbs). I then got rid of the cheesy bases and put a Leupold (A-Bolt, not MAG, standard bases fit perfect) 2 piece base on it. The Zeiss 4-14 look great.
Back to range. Still not consisent. Did get some groups down to 1.5 inches, far less than the promise of Sako. The ammo being used was : Double Tap 200 AB, Win 180 Ballistic Tip, Fusion 180 and Federal 180 AB. Then, I shot some 180 Win Power point, 180 grain.
Can you guess what shot the best? Yup the cheap stuff. Almost one hole. But still not consistent. It would do 2 holes overlapping and then 2 more or 3 more overlapping but two inches low?
I measured the OAL and I notced the spec is 2.860 inches but all the above was about 2.79 to 2.80. The Powerpoint was 2.83.
So masters of shooting, is there anything I that I can learn from the above experience. I am new to getting into the details of rifles, but is that my Sako likes longer OAL? Does not like AB?
Although it shows promise, my Savage and 700 shoot better with almost any ammo.
