So this year will be my first using cast for deer. I have two loads that I have a high degree of confidence in as far as accuracy goes. One is the Lee 309-150-F, 50/50 COWW and SOWW air cooled, powder coat, gas checked. I'm guessing is going about 1900-2000fps. The other is the Lee 309-170-F, 50/50 COWW and SOWW air cooled, powder coat, gas checked. I'm guessing it is in the 1600-1700fps range.
Any shot I take on a deer will be less than 100 yards. I hunt for meat, so trying to strike the balance of a quick, ethical kill whilst minimizing meat loss. If you were in my shoes, which load would you choose, 150g or 170g?
