I will offer up a bit different opinion. I am a massive fan of both. Weatherby has a special place in my heart. I find on a lot of web sites you find Weatherby envy. Guys grew up hearing their dad's talk down the Weatherby because they couldn't afford one....Jealousy is the word (not saying that is the case with the above replies, most on this site are serious shooters and some as you seen do shoot the Roy's). So they naturally follow what they think they know. I have seen Weatherby's shoot with the best of them. The .300 Weatherby is an absolute beast of a round. My brother shoots the .300Roy in a Mark V topped with a Zeiss Conquest and I LOVE that gun. It is vicious on Elk shooting the Barnes 150gr TTSX. 500 yards is an EASY shot to make with this load and watched him do it twice on big bulls that dropped in their own tracks. HOWEVER I am not sure how well the high BC bullets like the Weatherby free bore. The general consensus on Berger is they like to be on the lands. Might want to ask around on that.
Now the other side...Tikka T3. obviously I am in also in love with Sako. Since Tikka is Sako you cannot go wrong as you have read on many of the posts above. My wife has a Tikka T3 in 25-06 and it is an amazing little gun. I love shooting it. I would definitely do the .300 WSM over a .300 Winbag. Sorry but I really am not a fan of the .300 Winbag or the .338 for that matter. I bought my son a 7mmWSM in a Savage Weather Warrior and am super impressed with the round and the rifle. Definitely am a WSM fan!
So if I was in your shoes......I would go with the Weatherby. You are already set up for it so why waste money getting setup for a different round? Of all the Roy's the .300 is the cheapest and most readily available. You can get brass for it from multiple manufacturers. Some at reasonable prices. You obviously have some reservations of the Tikka. This will always be in the back of your mind. I think if you go with the Weatherby you will not only have one of the best all time all around North American hunting rounds, you will also have confidence in your rifle. Confidence = better shooting, better shooting = meat in the freezer. Beside the V2 is Sub MOA guarenteed so how can you loose??
