I have a tikka T3 in .308, SS, bull barrel. And 2 Remington 700 bdls in .243 and .308. Love all three. I use the 700s for hunting, the tikka for competition.
I reload for all three. The tikka has shot a five shot group, at 100 yd of .172 personnel best. But consistently shoots five shot groups of .250-175. The Remington’s consistent at less than .500 and as low as .200. Most here may understand the measuring, for those who don’t, the bullets being .308 dia. the hole measuring after five shots, just .500- .200 over that dia. So that’s Five shots in one ½ inch hole, not five shots ½ inch a part. So JIMO all three do very well. And I have beat out some very expensive guns on the range. And the glass does play a very big role in that.
Price plays a role in the quality of the scope, but there are some lower cost scopes, of good quality. That said a cheap scope or sometimes a high cost scope of low quality as well as the mounts, on a quality rifle, can give very bad results, that many blame the rife for.
There others I shoot with who use tikka’s, each gun has their own sweet spots, off the lands, powder load, and even primers. Finding the right combination, the shooter with, rife, scope, mounts, and ammo
