Finman Posted May 1, 2011 Report Share Posted May 1, 2011 Hi chaps, a favour really from anyone who has access to the Hornady Manual (or knows how to get it online...): I wish to reload some 129gn SSTs for my 6.5x55 and use N160. I cannot find any info on the manuals I have for this bullet (I have Vihtavuori, Hodgdon, Accurate and IMR). I would be greatful if someone can let me know the min-max range for this powder and also the SAAMI measurement for the cartdridge. best wishes, Finman Link to comment Share on other sites More sharing options...
6mmBR Posted May 1, 2011 Report Share Posted May 1, 2011 This is what quick load predicts for a charge of N160 set at max cartridge length of 3.150" I assumed barrel length was 24" so may vary +/- depending on your barrel length. Cartridge : 6.5 x 55 Swedish Bullet : .264, 129, Hornady SST InterLock 26202 Useable Case Capaci: 52.836 grain H2O = 3.431 cm³ Cartridge O.A.L. L6: 3.150 inch = 80.01 mm Barrel Length : 24.0 inch = 609.6 mm Powder : Vihtavuori N160 Predicted data by increasing and decreasing the given charge, incremented in steps of 2.0% of nominal charge.

Finman Posted May 2, 2011 Author Report Share Posted May 2, 2011 Guys, I am in your debt! thank you for taking the time and posting these. I assume that the difference between the Quickload and the Hornady maximum loads must lie on the Americans thinking that this load is safe on an old military action... thank you again for all your help, best wishes, Finman Link to comment Share on other sites More sharing options...
