Anyone got any idea where to start with this because I am seeing a lot of conflicting information on here and in the books.
hi mate what 65 are you usein
Don't know about 560 but I use 46 grains of N160, not saying its safe in yours though! A lot of the online data conflicts, try comparing with a Nosler manual.
a quick play on quickload show starting charge at 49.2 to max charge of 51.6,hope this helpsAnyone got any idea where to start with this because I am seeing a lot of conflicting information on here and in the books.
Hi Pointblank,Had a bit of a play today into a heap of topsoil and I am getting 2900fps with 50.2 grains. Not had chance to check grouping yet but I know where I am heading. 50.5 was starting to show a bit a pressure signs.
Cheers Pointbank,N560. I think others use 46g of n160 in their rifles
Hi PB and all.
I have been reloading with 52.5 grains of N560 with 120grain Sierras in Lapua cases for around ten years now. I am getting around 2970fps from my Sako 75 with a 23" barrel and around 2890 from my BSA CF2 stutzen 19" barrel. I see no signs of pressure problems and have reloaded the cases around seven to eight times each (primer pockets are as tight as when new).
Vhit state 52.7 grains as Max load and my load sits just under that.
I get just under 1" 3shot groups with the Sako and just over from the CF2. I think that the CF2 would like a heavier/longer bullet, but don't see any reason to change (although I often think about it).
Not suggesting that your bullet/powder/case combination wil behave the same, but thought you might like the above information.
