I built a 28 nosler on a tikka and it is fine. 3.37 is plenty long for 180s which seem to be what all the guys are moving toward. The 180hyb shot better than anything but nothing shot bad. Love the cartridgeI love my 28 nosler it's flat shooting and hard hitting. I'm running 195s at 3.8in max coal with nv570. Very accurate! Wouldn't mess with a 28 on a tikka action the mags just aren't long enough to use the cartridge with heavier bullets. I shoot have shot whitetail with mine but prefer my 6.5-284 for obvious reasons. If you have any questions feel free to send me a PM.
