help, bolt not wanting to come out
my 7mm just started giving me problems and i need some help from LRHM, i only have 25 rounds through it, brand new and just broke in. Well just recently, i shoot and then the bolt lets me lift it up and does not want to let me pull back, ( it will open with alot of force) its not effecting the accuracy at all it will shoot 3 bullets under an inch but it bothers me how hard it is to get back. now i looked inside and i can see tiny bits of brass by where they bullet goes in the barrel and there is scuff marks on the brass about 1/3rd of the way up from the bottom of it.
does anyone know what is causing this? it didnt start untill about 22rds in.
i am taking it to a gunsmith today but just curious as to what it is.
