    How True is this graph?

    Re: How True is this graph? Over on the 223 page, it says 500 cases cost $108 and then on the bottom it uses a figure of $0.22 per case. This implies he is not reusing cases. I reuse cases and I am seeing costs of about what he sees if you subtract out case cost.

    Powder burn rate for longer barrel

    Re: Powder burn rate for longer barrel Given the 30" barrel I might start with something as slow as 3031. But anything from 3031 through Varget, you should be able to word up a dandy load. OCW is a goog philosophical starting point. Longer barrels should work better with slightly slower...

    The Dreaded Donut What is the Cause?

    Re: The Dreaded Donut What is the Cause? Ok, the physics of the situation: There is more brass per unit radius in the shoulder than in the neck. Therefore as the shoulder is pushed up into the neck region by firing and by resizing the thickness of the botton of the neck increases. So the...

    Range Report Conditions at the range today

    Re: Conditions at the range today Low humidity means that the atmosphere is thicker (for the same reason that clouds float.) It shouldn't be "all that much" but with teh combination of reduced wind and thicker atmosphere, means the projectiles were slowing down faster.

    How many reloads become unsafe?

    Re: How many reloads become unsafe? As an example, I have a lot (50 pieces) of brass that has gone though 36 reload cycles, but I must admit its getting old. I shoot a rather stiff but sane load of 47.8 gr Varget with 155 Scenars at 2.943" or 0.15 jump. I have not lost a single primer...

    Is +/- .3 close enough for stick powders?

    Re: Is +/- .3 close enough for stick powders? My experience with Varget, after and OCW development and a sampling of the Charge Weight window, is that Varget with 155 Scenars will tollerate 0.25 gr. That is +/- 0.125 gr. My thrower throw +/- 0.25 gr, so I set it up 0.2 gr low and trickle up...

    Range Report Spindrift

    Re: Spindrift Inside 1000 yards, spin drift is essentially negligible, compared to the natural dispersion from shot to shot--even after you have all the ballistics (wind elevation) completely accounted for. You will not be able to measure SD at 1000 yards with a gun that shoots 1 MoA at 1000...
