Hey--
Moly coated stands for "Molybdenum disulfide" and it is supposed to prevent your barrel from fouling so quickly and it is supposed to be a "lubricant", therefore it will to function both in the barrel to reduce wear, ie a lubricant normally does that and some also feel it works ballistically as well, while the bullet is on its way to the target. You will hear many argue about the advantages of moly coated verses NOT moly coated bullets. I have used both, and quite frankly I have NOT observed a difference, but what the H E double hockey sticks do I know.
Anyway, your Tikka has a fast twist and is supposed to love heavier grain bullets than what you bought but hey try them and maybe your tikka will like them. My off the cuff recommendation would be to try 65 grain in your Tikka. I have a Reminton 223 with a 1 in 12 twist and I shoot the Black Hills in 52 and 55 grain and it LOVES them... yum yum. I can shoot at 50 yards up to 200 without moving the scope settings, yes it is that flat!! I don't know about 300 yards yet. I would guess I will have to adjust but I like what I have seen so far from my Black Hills ammo, and I hope you do too. The 55 grain should work a bit better for you because I think you have a 1 in 9 twist. 65 gr or higher are supposed to be better for that twist. I hope this info helps... and have fUn!
