This afternoon I decided to shoot some loads through my Competition Chronograph then run some calculations on my Ballistic Basics software.
Loads I had at my disposal today were:
1)Winchester White Box 240gr jacketed soft point
2)Buffalo Bore 270gr jacketed soft point
Results:
Winchester 240gr - avg. velocity = 1840 fps rounded
Buffalo Bore 270gr - avg. velocity = 1750 fps rounded
Calculated BC for each bullet as follows:
240gr jacketed soft point = 0.172
270gr jacketed soft point = 0.193
Using my Ballistics Basics software, I determined the following:
240gr Winchester loads -
100 yard sight in = 1398fps and 1042 foot pounds of energy
270gr Buffalo Bore loads -
100 yard sight in = 1370fps and 1126 foot pounds of energy
The drop at 125 yards would be -1.87 inches for the 240gr and -2.02 inches for the 270gr loads.
Both loads would still have good energy out to almost 150 yards. The 240gr load would be around 934 and the 270gr around 1021. If a 150 yard shot was required this would prove to be sufficient energy for deer sized game.
In light of my work with these two loads I feel very confident in the 44 magnums capabilities through my Ruger 77/44.
I doubt a 150 yard shot is needed and it is very hard to accomplish that in a woods environment. The longest shot I have ever had was about 115 yards over the last 25 plus years I have deer hunted.
Hope this helps owners of any rifle chambered in the 44 magnum feel comfortable in it's deer dispatching capabilities.
