Hi Guys
I'm reloading
190gr Hornady BTSP
Varget
.308 Winchester
Tikka lite. I think a 22" barrel.
Here is the data that is confusing:
Hodgdon: (http ://data.hodgdon.com/cartridge_load.asp)
41.0 - 44.0 (Compressed at 44)
Lee: (Modern Reloading Second Edition, Page 431, 190 grain jacketed bullet)
41.0 - 44.0
Hornady: (7th Edition Hornady Handbook of Cartridge Reloading, Page 450, 190 grain BTSP)
31.3 - 40.9
So right next to each other:
41-44C
41-44
31.3-40.9
The problem is the max of one is the min of the other.
I took this load out today, loaded up 41, 41.5, 42, 42.5, 43, 43.5, 44 grains of varget, 5 of each. I am teaching a friend the basics of reloading, and had brought out the Hornady book to show pressures, speed (was chronying loads), etc. We look in the Hornady book and sure enough, the 41 grains was over the maximum. I was sure I had loaded right (I had loaded 41 before in the same gun) but we fired that 41 grain, and the primer was fairly flat and the velocity was 2500, in the maximum zone according to the manual. Wasted trip to the range as we obviously didn't shoot any of the others, and now I'll have to unload them.
What gives? Anyone have any ideas why this is? Have you guys seen this before? I essentially was getting pressure signs with a load that shows as minimum in two manuals.
Thanks,
Barry
