"It is like going from a Lincoln Navigator to a Ford Explorer. Grin But seriously, how does your encore shoot?"
It is like going from a Lincoln to a Ferrari is what you meant.
The fifteen minute wait is mandatory at the range in 70 degree weather, as was stated, the sabots will get too hot, groups will go to hell. Now, in 30 degree weather, you might not have to wait at all, or only a few minutes between shots. I have not gone to the range in 30 degree weather.
This problem has little or no affect on the hunter, as we all know the whole ball game rides on the first shot. Plus, usually you are hunting in cool weather. I killed my buck this year in North Carolina, it was 28 degrees at the time. Had I needed a quick follow up shot it would have been accurate.
But I didn't need one.
