Thread: hard bolt lift

  1. #1

    hard bolt lift

    I have been loading 150 nosler bt, with 43 grains of imr 4895 for a .308 scout. Occasionally, 1 out of every 12 approx, i am getting a sticky bolt. I am well in the loading chart parameters and my brass/primers are showing no sign of high pressure. I am using geco brass and federal. Any ideas? Regards, Ed.

    I get a tight bolt on my sauer .243 if i leave a case in the chamber to cool after firing happens with factory loads and homeloads i've always put it down to having a tight chamber oo-er.

    Are you mixing makes (Lots) of brass or are you getting this with any kind of brass? Are you trimming with every reloading? I know that you are in the middle of the loading chart but sometimes odd things happen with pressure that has nothing to do with powder charge.~Muir

    I am using federal and geco brass. I am not trimming unless case is longer than 2.015 inch as per chart in lee reloading manual. I have fired the brass 3 times now and have not trimmed brass as none have gone above the chart dimensions. I am neck sizing only with no crimp.When loading magazine i only use one type of brass, ie 5 geco then 5 federal. Regards, Ed.

    Next time it happens, remove the offending case from the loading block and set it aside. Keep doing it until you see a pattern; keeping these cases out of the mix from now on. Measure rim dimensions, OAL, etc. If you see no pattern emerging then you can look towards your rifle.~Muir

    This used to happen with a Tikka 595 in .243 that I had for a goodly time, it would seem that the .243 is prone to this if you neck resize only.. Try Full length resize maybe and check again ?

    I had the same problem with reloads that were third timers or more i had to full size to knock the sholder of the case back after that every thing was great.

    Eddie,
    Try different brass if you can get some - Norma - RWS - Winchester. These are normally very reliable 'everyday' brass. No one gets excited about the weight or apparent strength of these cases besides the heavier brands, but my experience is that in general they are very reliable.
    If they work better - then get rid of the other stuff. I've witnessed a .25-06 get a bit 'picky' with some cases which were hard to extract after firing - some had to be rodded out at home which was a darned nuisance when out at night foxing, and it became the norm to have another rifle with the fellow who was doing the lamping.
    A change of case brand solved the problem.

    As has already been suggested earlier in this thread, try to put the hard extraction cases aside - in a different pocket, and see if there's any comparison between them - then afterwards - the others which extracted normally. Outside case dimensions at shoulder and base - length from base to shoulder - diameter dimensons at neck - (Inside and out).

    Too thick a neck wall, pushed outwards by the seated bullet, might create a crimp effect when the cartridge enters the chamber, especially if the chamber neck is a bit on the tight side. We all length-size the case necks because the brass flows down there - but we seldom think about neck wall thickness.
    Remember that during extraction of the case from the sizer die, the neck expander ball on the decapping pin expands the INSIDE of the case neck out to suitable bullet seating dimensions whilst the bullet then pushes the neck that bit further out when seated.
    So, there's nothing to govern the size of the OUTSIDE of the neck although all other parts of the case affected by the the die have been squeezed inwards for an easy fit.

    I'd start with the brass as Muir says and work on from there. You can see that you could write a small book on its own on this one subject, but one step at a time.

    Good luck.
