Just received this email from a Canadian BR record holder:
Hey Peter
"Sighted in at 500 meters for our benchrest match June 27th.
That Sightron 45X is a nice f.....g scope. I can see 6mm bullet holes at 500.
I put an 8 twist on my 6ppc Heavy Varmint and am shooting 95 grain Bergers.
Cheers"
Specials will soon be available on many popular models.
