Stanley... for me the rifle it is not so heavy. (I am just 180 pound - 5'8" tall, I am not HEMAN!!!) but....
I thought the weight will be worst than the Gamo Hunter Extreme 1500 .177 that I owned, that was heavy for me.
Another thing is the manner I hold the sumatra, close to the trigger guard in the metal area the,
rifle it is not balanced at all, it is more heavy on the front section as it is by logic with the air reservors.
In my case I will use it bench rest for +100 yards at the range.
I love all that things of scope moa calculations, I am learning with a practice software, now it is time to practice the knowledge
Just for fun,....
Take care
