[QUOTE="Tac-O, post: 1932324, member: 109994"] I cleaned my bore really well after 275 rounds. I first used hoppes 9 to remove the powder to see how much copper fouling there was near the muzzle and I only saw a few very small streaks in the grooves. After doing an intensive clean, I shot 20 rounds at the range, then cleaned after those 20 rounds. I did the same thing, using hoppes 9 first to remove the powder. After doing this, I could see two large long copper fouling streaks on two of the lands. This is different than all the other times I've cleaned the bore. When I was in the habit of cleaning after every range trip of 20-25 rounds, there wouldn't be much, if any copper fouling near the muzzle that I could see. So, I'm wondering if I did something during the intensive clean to cause this, or if it's due to leaving the bore untouched for 275 rounds, or if it's due to a slightly hotter powder charge. With my cleaning after the 275 rounds, I did a few rounds of using sharp shootr acclerator and tactical advantage, some bronze brushing (very gently), a few rounds of foaming wipe out and accelerator, and I also used CLR a couple of times. Yes, the CLR that you use for removing hard water scale. I've used it before for removing hard carbon and it does seem to remove some carbon that other solvents won't. I didn't leave it in the bore more than 5 minutes and only used it a couple of times. All the reports I've seen of using CLR in a stainless bore note that there is no damage to the bore (verified by other's use of a bore scope). Also, I've got a quality bore guide and a coated rod that I wipe every time I remove it from the bore. So, I'm pretty sure that I didn't damage the bore in any way when cleaning. One thing I had been doing while not cleaning the bore, was spinning a .338 caliber bronze brush with a patch wrapped around it to clean the neck part of my chamber. I know I got a little too far in some times, hitting the lands, but I was doing it by hand gently, so I don't think I would have caused any damage there. So in seeing the large copper fouling streaks after only 20 rounds, is it more likely: The near max load I was shooting through those 20 rounds causing more copper deposition down the bore? Scratching of the bore from shooting down a dirty bore for 275 rounds? Damage to the lands from when I was cleaning the chamber neck area causing more copper deposition down the bore? I guess it's all just guesswork without having a bore scope. But when putting a solvent or oil patch down the bore, it feels very smooth all the way. [/QUOTE]
