Hello to all, this is my first post here.  I come to your mountain in search of knowledge! 

I just picked up a Weatherby Vanguard in 270 Weatherby Vanguard. From the information i have gathered at this point, it was manufactured somewhere from the Late 1980's to early 1990's.  The rifle is in transit to me at this point, so I do not physically have it in my hands yet, but soon. 

So my questions are:
How are the triggers on this model?  Are these triggers replaceable with a Timney?
Should I assume the 1 1/2" group accuracy with this rifle, with premium ammunition?
Anybody have one of these? Good? Bad?

Thanks
