That sounds right because Kirby used a Lilja #3 contour barrel on my 300 Win Mag and he was telling me about his 7mm AM using a similar contour barrel. Mine is 25 1/2" long. I think his 7mm AM is about 27-28 inches long if I recall correctly. He smoked an antelope with his 7mm AM way out there the season he and I discussed this. Good luck with you're rifle builds. I'm envious, but I've got about all the rifles I can load and shoot right now. Maybe I need to sell a couple and start afresh!
