Getting confusing here now.....

I noticed how 9 out of 10 .450 bpe rifles weigh in at between 10 and 10.5 lbs....how come? There is no need for this weight on this caliber gun surely???

You can often find 577's at 10 lbs weight......

I wonder if the weight thing only applies to bore guns....dont think the express rounds can be loaded up or down much, or am i wrong? bullet weight is always about the same too, no?

All the best,

Ben
