Glad you got the stuck brush out! Your method obviously worked. Would agree, could have been removed by pushing. Will say, hardly ever use a brush in common .22 LR firearms since .22 LR ammo is just lead bullets. Impossible for lead to wear any kind of a normal steel barrel as used for a firearm. For that matter, impossible for a bore brush to wear a bore of any rifle unless that brush is one of the stainless steel types. Brass, phosphor-bronze, etc., are not anywhere near the hardness of steel. The brush will wear out. If the core is steel, it could conceivably by being bent come into contact with the bore. That would obviously not be a good thing. But, a bronze/phosphor-bronze brush w/ a non-steel core will not damage the bore of a firearm through common use. JMHO. Sincerely. bruce.
