Went to the nearby AF base's range to try the Tikka .308Win @ 300 meters (330yds) for the first time. Weather was really nice, only light winds, temperature at 70F and the sun was shining. I had zeroed the rifle at 100m so I calculated an estimate with an app on my phone as to how much I should adjust the elevation on my scope. I had to guess the velocity based on load charts because I don't have a cronograph. The app suggested 19 clicks, but I was also using a supressor so I decided to add 25 clicks and it was spot on. I was using a load I developed last fall and it seemed to be working just fine. I didn't measure the groups but I think they were 3"-ish. I still need to practice my trigger work a lot, but I think I did ok for the first time at 300. Might do a trigger job on the gun also, might help a bit.

Load data:
Zenith primers
Hornady Match brass
Lapua Scenar S HPBT 168gr
46.7grs of Vihtavuori N550 powder
OAL 2.815"


1st try with the gestimated elevation.


Couple other groups.

Not too shabby for the first time at 300m.Your still shooting MOA!
Doesn't the Tikka have an adjustable trigger? There's nothing wrong with those groups at that range,with a little more range time,I'm sure they would get tighter for you.

Thanks Tx. Yeah, it can be adjusted from 2 to 4 lbs. Decreasing the trigger pull weight might help some, but I'd like the trigger to have a bit more feel when it breaks. It's a smooth pull, but I can't tell when it's going to brake

Nice shooting for the first outting. What is the weight on the tikka?

Nice range too, did you pay to go there?
Thanks. The gun weighs ~10.5lbs with the scope and supressor, ~8.2lbs w/o the accessories.

I pay a 40$ yearly fee to a reservist organization and get to use the Air Force base's ranges 4 days a week during spring and summer.
