Well I have had the gun for 3 years. From the beginning I could never get the thing to shot factory loads. The pattern the factory loads was a 4 inch vertical straight line at 100 yards. So I started hand loading. I started with 115 grain ct ballistic tips. The gun still had the inconstancies that it did before so I changed the scope rings. The next pattern was about .5 inch at 100 yards. But I lost all my reloading records. So this year I started back and I could not get the gun to shot consistently. Now I have switched to 100 grain bullets because I found a twist to bullet weight chart. My gun is a tikka 25 cal with 1 in 10" twist. And according to the chart my gun can not stabilize the 115 grain bullets. The 100 grain bullets are what they recommended. So tried some this week end and the gun was a lot more consistent but it was still 2.5" group at 100. I am really not satisfied with this pattern. I contacted berretta and they told me to send the gun back and they would look at it.
