I have a couple bricks and they seem very quiet in an unsupressed
rifle. They make up for the low speed with more weight to maintain
down range performance.
Why not use .22 shorts?
I think that 65gr bullet would do better on squirrels if that is what
you do.
Ahh, squirrel hunting...that's what brave men do, because they can make
squirrelskin caps for their grandkids and grill the meat on the barbecue.
Don't know about the cap part, but bagging squirrel is better for you than buying those pre-assassinated steaks, chops, and breasts for $9.95 a lb.
Lean meat with no antibiotics and no growth hormones.
