    Finally was able to pick up my CZ527 American in 17 Hornet last week, yea!
    Question could you work up a pressure curve in the 17 Hornet case using Accurate 1680 as a propellant? B4 the 17 Hornady Hornet came out Accurate 1680 had been the powder of choice in this case capacity. Pushing 20 grain pills at velocities 3750 to 3800ish.

    Recent Load data from Ramshot propellants would indicate that Max pressures are being reached around 3400FPS with the A1680 propellant.

    On the other hand Hornady Load data indicates while using a Winchester small rifle primer and 12.4 grains of A1680 one may reach a velocity of 3750 from a 24" Savage tube. Ramshot load data maxes out at roughly 1 grain less A1680 propellant as I recall. I am not able to access that Ramshot file at the moment.


    No hurry as I hav not yet found this propellant available for sale for some time.

    Thank you!
