Phew...at last, Rome, the naked truth !!
We do have some good experts here, I'm usually always impressed, but it WAS fun for the rest of us lowly guessers.
Glad you didn't mind my input, nice to hear from you. After all... my Russian ($60 secondhand) TOZ "8M" heavy barrel .22LR can shoot as well as a BR50 Anchutz costing $3,500, and better than some others up to 50m on RF metalic silhouettes!!
Go with it Rome...!
