Took another fox on Friday night with the Tikka .222Rem whilst out with a mate. I wasn't happy with the Zero though for the longer range shots because the rifle was zero'd at 100 which gave me a drop of over 3 inches at 200yds.
I checked out exbal this morning to find the point blank range for 1.5", Exbal suggested 161yds was the best I could get with this rifle/ammo combination, so I set off down the farm to get the zero set up at 160yds.
I fired 3 warm up shots then aimed 1 shot at a clean target to find where the POI was. I altered the turrets to compensate for the error, placed a fresh target up at 160yds and fired 6 shots at the target.
The group above is a 6 shot group at 160yds which equates to .390moa which I thought was amazing for a little factory Tikka T3. The rifle is a totally factory rifle without any custom mods what so ever, I have spent many hours neck turning, batching and preping the cases so I have put some hours in developing the load, but it just goes to show what can be achieved with a factory stick and a little perseverance.
Please forgive the large Diamond target, I am using a 3-12x50 Zeiss Duralyt scope so I need a biggish target at 160yds to aim at.
