I have search various places including here and can't seem to find the answer
Does the 453 varmint have the same diameter barrel as the 455 model? Or is the 455 thicker? I like the idea of the single set trigger on the 453 but I want the heavy barrel , this is more important to me
 
I don`t have the specs on those barrels right now however the difference would be so small that you would not notice it when shooting. The variation in ammo as well as the manufacturing difference in any particular barrel will cause more variation in groups. I haven`t used a 453 trigger but the Timney on my 455 is a little better than the 452 V trigger.
 
the 455 V is a straight barrel without taper, the 453 has a slight taper. You would see not difference in accuracy except the 455 V is not hunter silhouette legal.
