I shoot a 500 that weighs 9 lbs 12 oz and it really isn't that bad. I prefer a light gun but I think 8 lbs 10 oz is very light for this caliber but it sure would make a neat cast bullet gun. For $5000 you can't hardly find a shooter 500 BPE. I will be very interested in hearing how these guns pan out. I wonder if their 577 and 600 were going to be under 10 lbs. Yikes that would not be my idea of fun.
