Inside my new Criterion barrel

So a related question. If that is residue from bore cleaning solutions, does that affect your first couple of shots out of a clean barrel?

I'm guessing anything other than a clean,dry bore will affect the first few shots

It's like having a supermodel internet chat girlfriend then meeting her in person for the first time

I only have messed with 10 or so cm barrels, so I don't have a good answer. 99% sure it doesn't, because I cleaned them in acetone, but I'll defer to more knowledgeable guys.

OP, really glad you got it fixed.

Good call MRAM!

I've never had problems using brakeklean. But use the one with the green label. Works great to neutralize sweets and other cooper cleaners. Also for removing and softening carbon fouling.

jlreff have you ever read the material safety data sheet on the paper label on the can . I have used cases of the green label at work . It's the industrial grade brakleen and has the same warnings on it . I was doing a welding test one time and a guy sprayed me and my coupon with it while I was welding it nearly killed me and there was no repairing the hydrogen damage to the coupon . Phosgene was used by Germay to kill thousands as it was cheaper to produce then other toxins , until 911 it was used to kill prairie dogs . Just take care with it's use if you use it in your home or shop in the winter while your furnace is running .

I am as guilty as any one else of not always reading the MSDS for all of the different products that I have and do use . Chlorine bleach is a good example of the need to do this ,when used in combination with some detergents or acid type products it puts off chlorine gas and a worker in a restaurant just did that several were hospitalized and the manager died trying to clean up the mess and flush it down the drain . It made National News . Just please read up on the products that we expose our families and our selves to . at one time DDT and asbestos were thought to be miracle products .

I have read the m s d s, plus they've gone to a global m s d s guide line. I wear gloves plenty of ventilation and keep ignition sources out of the way. Use the green label because it's not as bad on plastic or wood stocks. By the way brichwood Casey gunscruber is the same stuff.

I did not read the label before using this on a cheaper gun and literally melted the plastic stock in front of my eyes.
