I have both guns and prefer the feel and handling of the A5 over the SBE2. The recoil is about the same on both. I have not worked up a load / choke combination for the A5 as I got it last Fall. I believe William with Sumtoy has worked up a load / choke for the gun. I found his other chokes to be very good in my Versa Max & A400 Xtreme. Also, he has great customer service.
