Just scoped it and want to go dial it in but don't have time to mess around with hand loads

What do you guys recommend?

Just buy some el-cheapo Remington corelokts and Federal fusions or the like... Let us know how she shoots. One of my buddies has one and it's not responding well to his handloads...I hope yours does better than his...

The Fusion load shoots well in mine and is very unfriendly to our local whitetails

I don't have the Tikka but I do have 1 in 8 twisted .223 - Fiocchi ammo with 50 V-max, 69 Sierra MK, and Sierra 77 OTM loads, and the Hornaday Match ammo with their 75 HPBT all shoot very accurately. I use my bigger guns for big game so I don't have an opinion on these loads effectiveness beyond paper, steel, and varmints.

Right on. Thanks guys!

I hear the fast twist is good for heavier bullets but I may start with the Hornady with the 55 grn V-Max

If you are gonna shoot something in that weight I'd strongly recommend going 53gr vmax. Has the same profile from the ogive to tip as the 75 amax. 53 has a .290 g1 bc versus the 55's .255.

Thanks!

Do you have an opinion on which factory ammo to go with? Should I try something other than the 53gr amax?

Are you up against any kind weight restrictions? I'd start with the 53's or something with a hornady 75 hpbt in it. I also prefer the 50 vmax over the 55, but that's just personal preference... If it were my rifle I'd be loading 75 Amax's though!

Federal Fusions always seem to be accurate in a wide variety of firearms. I'd start there.

Winchester 64gr Power Point Load.

Federal Gold Medal Match 69gr Sierra Matchkings

If you have access to them, or find them online, black hills 52 match hollow point shot sub 1/2moa in 2 rifles I owned previously. The remanufactured (blue box) was better than the new loads for me
