[QUOTE="AZShooter, post: 1662703, member: 5219"] I would also suggest you inspect it with a borescope. I took good care of my first 257 which had a SS 3 groove 1 in 10 Lilja. I didn't shoot more than three at a row for its life with cooling before the next string. It had to be replaced before it got to 1000 rounds. Imagine if your barrel was shot with longer strings how fast it could be worn out. The barrel's symptoms could not be ignored. It took a long time to remove the fouling. It needed at least 3 fouling shots to settle in and would shoot okay for 5-8 rounds then shoot all over the place. A borescope showed firecracking and larger longitudinal cracks up the bore for over 8"! [/QUOTE]
