    Hi,


    i loaded a couple of rounds for my finnwolf and noticed that the primers were a bit flat and brass hard to extract.
    I had a starting load with a 100gr bullet.

    Is the finnwolf prone for sticky bolt or does not like some bullets?

    How tight are the chambers ?

    Regards

    Sounds to me that you are loading at or over the maximum pressure. No one can solve your reloading issues over the internet based on some vague description of what is happening. Finnwolfs aren't known for any chamber problems or sticky bolts, so why don't you lower your charge weight & see if the problems go away?

    I am already at recommended starting load. Factory ammo extracts fine btw. So I don't think it's too much pressure. But I will back off even more.

    If you are at recommended starting charge weight & factory ammo extracts fine, then your problem may be your brass is not sized properly or your scale is off. Sometimes semi-auto & lever action guns need a "Small Base Sizing Die" to size the body of the case down to a diameter that will allow easier chambering & extraction. Many things it "could" be. You'll just have to eliminate one thing at a time to discover what it is.

    Hi, I would like to "clear up" what was happening.
    I used Federal 210 primers which appear to be very soft.
    That caused more flattened out primers.
    The hard extraction was gone after I honed the chamber slightly with steel wool.
    Both signs together made me think of overpressure;)

    Glad you got it figured out. Yes, Federal primers(some) have been known to be soft in the past. I often cross reference several manuals and/or reputable web data to start with a load.

    It’s hard to imaging a true starting load would give you overpressure signs. As eluded to, flattened primers can have a few less common explanations, brass or chamber issues.
