    Reloading for 300 win. I will get a great group one day, the next I will get a couple bad flyers. I weighed 3 loads twice. Found 2 loads were .20 grns heavy and 1 was .20 light. .40 grn difference. Is that enough to make a big difference in speed and accuracy?

    My 2C is that it depends on how far out you are shooting, and how bad your flyers are. If you are seeing 1-2" flyers at 100 or 200 yards, I would not expect that to be caused by slight changes in powder charges. It is more likely scope, bedding, or shooter related (I have a 300WSM that I found out threw flyers due to #3, please don't think I'm saying you can't shoot - I'm just sharing personal experience:D)

    IMO as well....

    When I'm being really critical about charges, I weigh each and every one with my beam scale (I have an inherent distrust for electronic scales, no matter what brand).

    Bulk loading, I weigh every tenth charge. Now, I use a culver type charging station instead of the normal varible capacity like RCBS or Lee or Hornady sells. A Culver charging station throws inherently more accurate charges but costs substantially more and on the plus side, a Culver unit is unaffected by powder shape. Normal displacement type charging stations do fine with spherical powder but not so good with extruded rod powders. Culver measures don't care about powder extruded shape, they throw consistent charges no matter what.

    Finally a slight powder variation shouldn't cause serious accuracy issues, Factory rounds vary a bit. Pull some and weigh them sometime and compare.

    What is your rifle/optics set-up, and what do your flyers look like?

    Even 1 grain makes a difference. ..
    I use and trust rcbs 10-10 scale.. no batteries needed, just in case shit hits the fan, no power around no worries

    I have found that sometimes small deviations in powder will make a difference and sometimes not. Usually it won't matter if using large capacity case and slow burning propellant. I weigh each charge on my RCBS 10-10 balance beam scale when loading rifle cartridges. I tried another brand BB scale once and it was not consistent at all, so I returned it and got a refund. If I weigh each one down to a gnat's ass I don't have to worry about that causing inconsistency in my loads. That eliminates one possibility if components don't make a good mix.

    Seeing that other folks operate on the 'old school' train of thought like I do, makes me feel good. Always been a beam scale person. I just can't trust an electronic scale. Beam scales are inherently accurate and inherently simple, especially the 3 poise type.

    So long as the fulcrum is clean, there is no chance of inaccuracy or repetitve error.

    If it's good enough to weigh narcotics, it's good enough.......:D

    When you are loading for long range, such as F-Class 1 granule of powder will make a diff. 1 granule of Varget weighs .002 grain JVON

    Like I said, dope dealers don't use electronic scales, never have and dope is a bit more expensive per 'granule' than powder is.

    You seem to know a lot about dope dealers! Hopefully you're law enforcement!!!

    I use a balance beam also do not trust electronic scales.

    You could say that. Lets just say I'm affiliated.

    Check,,,check...and re-check the weight on a balance beam against a GOOD QUALITY electronic scale. You'll see they end up the same...and with the speed of an electronic thats just the way I have to go.
