You have an excellent load there, congrats. I have said it before that the 300 WSM is one of the best 30 cal cartridges out there. Pretty easy to load it like a 308 for mild recoil or all the way up to full power loads. By far my favorite 30 cal cartridge.
Not that exact combination but you never hear about the Ballistic Tips coming apart in flight. For accuracy I think you have a good chance to find a good load. I know a guy who shot a nice Mulie with the 55 gr BT out of a 243.
Can't see you having any issues with the Ballistic Tips and it's very unlikely the Varmageddon will either. If you have the gun already I would give it a try.
Looks like a good start. Vihtavouri powders seem like really good stuff. if you can get those speeds safely that's pushing on the lower end of 300 WSM performance. In my last 30-06 I tried RL 22 with the 220 gr Partition and got 2550 fps, this is definitely a step up in performance. If you can...
Yep shot my first moose in 1990 with 220 gr Silvertips from a 30-06 at slightly less speed than a 300 H&H. Had jacket core separation on my 2 nd shot but they worked. First one sailed right through. Shot my first black bear too with that load.
