I like both the older A-Bolt, and the newer X-Bolt. Never owned either, but have shot plenty.
Training a couple of guys a few years back as they prepped for a Canadian caribou hunt. They both bought the standard synthetic stocked Browning X-Bolt in 7mmRemMag. I adjusted the triggers and mounted scopes for both of them. They were shooting Hornady 162grn ELD-X Precision Hunter ammo, and those two rifles were among the most accurate assembly line-manufactured hunting rifles I have ever shot.
More recent than that, I trained a guy as he prepped for an elk hunt in Idaho or Utah (I can't remember which one it was). He had a much fancier rifle; a Browning X-Bolt White Medallion in 7mmRemMag. He used the same Hornady ammo the previous fellows had used (I recommended it to him because I had seen how well it shot). That rifle shot every bit as well as the other two did. He was a bit older than me, and had never hunted before in his life.
The elk hunter gave me a holler when he got back from his hunt. The day they got to the hunting camp, the guide took them straight out to get a little hunting in. Found a small herd of elk cows, and the guy I trained dropped one cleanly at 308 yards.
