Go with the remington 700 i personally have 7 of them in varying calibers and had the chace to shoot a vangard and personally wouldnt want one if you gave it to me. vangard my have a gaurantee but its only as good as whats behind it where as a 700 has been proving it self for well over 40 years. and as far as the bolt breaking well personally i dont know what you would have to do to get one to break off. i have like i said 7 and every member of my family has at least a 700 and through all the gun shows and expos that either i or my family attends never seen or really even heard of it and my grandfathers goes to the international shot show every year and talked with the remington rep and and asked and said that in the 40+ years hes worked there he has only had to send out 1 new bolt on account of it breaking and the extractors will hold up to most shooting done with a bolt action to where you dont really need a m16 extractor.
