HW 80 .177 break in noise and pellet weight

[gshumway]

Thanks to everyone who responded to my first post about loose screws.

Thought I'd start this topic as I was getting off topic.

I have an acre of property.  Fenced in.  No problems shooting my HW 75.

As I was breaking in my HW 80 .177 with 7.33 grain pellets all of a sudden it seemed that the rifle sound became much louder.  Maybe the wind changed or I'm just old?

So after a proper break in with 10.65 grain pellets will the rifle quiet down any?  (I will install a quiet backstop so that's not a problem)

And lastly I chose 4 pellets to test.  Two are over 10 grains in weight.  For shooting targets what is the heaviest I can go?

Thanks very much

The 7.33 grain pellets are to light, breaking the sound barrier.

JSB 8.44 or Heavier.....bet ya the 8.44's do the job in the accuracy dept.

Enjoy that new shooter!

Thanks, I'll add that to my test.  I'll stay away from anything lighter.
