[QUOTE="jshepherd61, post: 3076721, member: 93960"] Just for reference I have two 7mm STW’s I built from scratch Identical. Defiance Anti action, MPA BA Ultralight chassis both Proof 26” barrel. I rebarreld one with a 26” carbon Bartlien barrel: now same load in each one is 160 fps faster velocity on the same chronograph. I am getting 3,002 fps out of my Christianson MPA 7 PRC with the factory Hornady 175 ELDx. Yes I got lucky and have a CA that shoots! Barrels can have as much as 100 to 200 fps difference between exact length and brand!!!! [/QUOTE]
