Quick Loads Data

[dezmick]

is there anyone that can get me some quick loads data using RL17 powder for a 300 WSM and 180 grn Interbond bullets, as well as 30-06 using 165 grn in both AccuBond and Interbond.

180gr bullet at 3k is a beautiful thing:

 Cartridge          : .300 WSM (CIP)
Bullet             : .308, 180, Hornady InterBond 30709
Useable Case Capaci: 69.680 grain H2O = 4.524 cm³
Cartridge O.A.L. L6: 2.860 inch = 72.64 mm
Barrel Length      : 24.0 inch = 609.6 mm
Powder             : Alliant Reloder-17

Predicted data by increasing and decreasing the given charge,
incremented in steps of 0.82% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !

Man, the data from Alliant is way off. They run up to 66 grains with a 180.

 

[Antelope_Sniper]

Alot of factors can effect a QL predictions.
As an example, it predicts a max of 64gr for the 180gr Hornady flat base bullets.
In addition I just used the default case capacity. A case with a larger capacity might allow a larger powder charge at the same pressure.

This QL data would be very close in my 300 WSM.Alliant's data is way too high for mine.I think maybe it's because I don't have any freebore to work with.I didn't shoot any 180gr bullets with the R-17,but 66.0grs of it was giving me 3220fps with a 165gr bullet.Alliant's data was showing that kind of velocity with 68.0grs.That's why you start low and work your way up and use a chronograph.
