Took some time yesterday to try out the Remington Hevishot 1 5/8oz #6's. Compared to my Winchester Supreme XX 2oz. #6's they shoot pretty much the same. The main difference is much less recoil and they both pattern the same. I don't think those 2 factors justify triple the price though. I'm sure the Hevishot have more energy but it wasn't noticeable during the shooting. I was shooting into a 1/2" piece of plywood supported on the ground. Both rounds knocked over the board out to 35 yards. At 40 yards the target didn't fall over. I also used a stock-type screw in choke (Trap Full) just for comparison. Boy, what a difference a turkey choke makes! I couldn't kill a turkey past 20 yards with a stock choke! I'll post pictures next week when I can.
Using 3" loads out of my 870 I feel comfortable out to around 35-40 yards. I was getting 6 pellets in the neck vertebrae/brain with each shot out to that range. Using a Remington Super Turkey Full choke. Might be better with different choke but not very easy to try other chokes.
