  1.  

    And your opinion on this matter is?

     

    For the record, mine is that he has done this several times before and to him this is all good publicity.

     

    Personally I think Chris Packham is an extremist, I think he's only one step away from the type who break into legal laboratories to free the caged rats used for drug testing or aggressive hunt saboteurs who disrupt a legal pursuit.

     

    His weapon is to use his celebrity, condoned by the BBC to pursue his biased agenda. His regular outrageous claims are swallowed as gospel by his narrow minded followers. Claiming Lapwings are in decline because they are being shot etc.

     

    Typically he's patron to this charity with some odd ideas about Foxes.

  2. I agree, a reloading scale can't be compared with an analytical balance but that's surely no reason not to regularly check it for accuracy and repeatability against a known standard. A lot of "measuring" that we do when trying to load an accurate round is actually comparing, making sure all our rounds are as consistent as possible, sometimes though, we do need to measure. When we do, it's nice to know your micrometer is telling the truth, checking it against a know standard slip gauge gives a certain amount of reassurance the bullet you are going to use to load your .303 is actually .311 and not a .308.

     

    +/- A tenth of a grain when loading rifle rounds will, in general, not matter a jot but where do you draw the line, +/- a 1/5th? If I'm shooting my 6.5-284 at 1000 yds at the best part of £1 a bang, it's really no more effort to weigh the powder as accurately as possible. Just the same with concentricity, neck tension, trim length and all the other steps to a well prepped case.

     

    My Pardini competition .32 centrefire pistol used a charge of 1.6 grains, my current .32 pistol uses 1 grain - really don't want to be 10% out with that.

     

    Here's a reloading scale showing a fair degree of linearity:

  3. Personally I wouldn't be without a set of checkweights. A Lyman or RCBS set of grain weights is around £40, they will last a lifetime and not lose value.

     

    Most reloading scales, if in good condition, tend to be fairly accurate in the 5-100 grain range, some do tail off toward the end of the range but usually only a couple of tenths of a grain. The problems begin when the scale isn't working as well as it should be and gives false readings.

     

    A good beam scale will be accurate to 1/10th grain (4-5 kernels of Varget), some will consistently register a single kernel of Varget or similar.

     

    I have seen many scales under/over read because of chipped knife edges, hairs of wire wool stuck to the magnets in the damper slot, poorly adjusted pan hanger stirrup etc.

     

    How do you know your scale is still reading consistently without some means of checking them?
