    that is right - provided the app isn't trying to correct for altitude and give you sea-level pressure (my Suunto will do that in some settings).  Sea level pressure is what's given by national weather stations so it's standardised for all users irrespective of local altitude.

    What you are trying to correct for is actual "station pressure" ie where you are.  Set your ballistic app to "station pressure" too.  

    In general correcting for air pressure and/or altitude only makes a usable difference if you have recorded zeroing conditions to extrapolate from - ie station pressure or sea-level pressure with altitude when you zero (along with temp and humidity).  What you are adjusting for is relative air density which is a combination of temperature humidity and pressure.  If you know that, apologies for mansplaining.

    Thank you that makes perfect sense now 

  2. Ok I have the Samsung s7 which apparently has a barometer built in so that might work.

    I am new to longer range shooting so excuse any daft questions. 

    If it reads the pressure at your location does that mean you don't need to know your feet above sea level ?

    The threads can be changed for about £65 or so by the importer, Jackson Rifles
    ...though that may take the total past what you are looking to spend

    Great mods though - got one in .30 with a 5/8-24 thread (not for sale)

    An alternative is to look for an adapter bushing - or have one made 

    Thank you but I have got a good deal from a rfd at my club.

    The acid should be neutralised by the hard water.

    I just rinse in softened water to remove the dirty water and lay on shop-towel on a tray and remove any excess water. Then in the oven on its lowest setting for about 30 minutes (or after cooking a roast as the oven cools) and they're pretty much dry.

    As I do all the cooking the wife never needs to know 😏

    Sounds like a plan

    Rinse in soapy water and rub a towel over them and leave in the airing cupboard over night. I used to leave them on a radiator but wifely wasn’t happy.

    That works for me, my wife gets the hump when I clean my ruger old army in the kitchen sink 

  6. My first post so Hello all

    I have just picked up a u/s cleaner from GT sonic it's a 100w unit and I am using Sea clean fluid, it seems to work well enough although it did take 3 cycles of 30 minutes to get the cases truly clean does that sound about right compared to the units any of you are running. 

    My brass was rather dirty to start with.
