RE: Win Ballistic Silvertip good load?
For deer Ballistic Tips are my favorite bullet. I have never seen a bullet put the spins on a big canadian buck faster than a NBT. Yes they are explosive but very effective when placed correctly. 9 out of 10 guys say they aim for the boiler room, keeping with that and assuming you can hit the pie plate they are a terrific choice IMO.
I would say if they group the best then use them. As far as the moly coating I have been told by many reloaders that they do nothing to your barrel as long as you clean and maintain it regularily. However I don' t believe the factory Win Ballistic Tips use actual moly coating, rather a paint dip ( I may be wrong but that was my impression!)
