i am not the one to start crap. BUT i been shooting barrel burners FOREVER. i cant afford it now.
that being said, my new chambering 270 BEE with the wrong powder(high flame temps) with 165/170 and shooting too long of strings, i can ruin my new barrel easily.
its just a fact of life, 'WHAT WORKS, WORKS" you know i considered 270 STW, but i know the performance will be short. heat checks in metal at 64,000 psi are impossible to avoid. so i have to run as fast as i can and keep it to heavy bullets and moderate speeds.
i have a buddy who owns THE GD KING....lazzaroni 7mm. it owns all of the rest by 500fps.....glad i dont have to replace his barrel.
500 is short barrel life, and long before 500 accuracy is gone.
later. sorry to once again disagree.
