I am liking the accuracy a ton but not sure if i want to go 2.0 or 1.5 for longer distance antelope shots. Leaning toward the 1.5 as looks like be a heck of a turkey head as well. Keeping the wacems for elk
For antelope, I would definitely go with the 2.0. They will fly identically, but since you more then likely be pulling both of them out of the dirt after they blow through the antelope, I would rather have the extra 1/2" hole in the animal to bleed out faster.
The flight isn't going to be impacted at all between the 1.5 and 2.0. You'll get more than enough penetration with the 2.0 on pronghorn. If it were me, my order would already be in for the 2.0s.
I shot the antelope in my picture last year at 60 yards with a 1.5 and it zipped right through him. This year ill probably be using the 2.0's for the larger hole on antelope
I would definitely go 2.0, I put a 2" Trypan all the way through a mature bull elk last fall. 28" 73lbs. I'd let my kids shoot the 1.5" at an antelope.
