Re: Handloading the 6.5x54 mm Mannlicher-Schoenauer
|
I don't have QL data for the 160gn Hornady RN bullet, but I have tested it to 39gns of IMR4350
with no pressure signs. However, the barrel on my MSch M1903 is shot out so nothing useful was gained from any of the loads I tested. Including those below with 140gn SST bullets.
The new Kreiger barrel in eight months time should tell a completely different story.
Attached is the 'Steves Pages' link: http://stevespages.com/264_8_160.html
Here is what the 140 SST looks like with a couple of different IMR powders. If there are any others let me know.
Cartridge : 6.5 x 54 Mannl. Schoen.
Bullet : .264, 140, Hornady SST 26302
Useable Case Capaci: 43.745 grain H2O = 2.840 cm³
Cartridge O.A.L. L6: 3.063 inch = 77.80 mm
Barrel Length : 22.0 inch = 558.8 mm
Powder : IMR 3031
Predicted data by increasing and decreasing the given charge,
incremented in steps of 2.0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !
