I just shot my new Maxus today for the first time with a Hevi-13 choke. I shot 3.5 inch hevi #6's and 3.5" magblends and 3" magblends since that is what I had.
I got an average of 172 with the 3 inch magblends. I got an average of 190 with the 3.5 inch magblends and I got an average of 230 with the hevi #6's.
I only shot 3 of each type of shell but was very impressed with the #6's. Temp was 39degrees here in NY with light wind and humidity around 45%.
When I had my SBE2...my gun liked a Rhino choke with 3.5" magblends...well over 200 hits with that combo.
