Hi to you all .I am 47 years old and recently bought my my first two centre fires brno zkw465,s in .22 hornet.I already own a .22lr nylon 66 purchased in 2006.Not so accurate that is the nylon 66. I got to know of the forum whilst searching for more info on the brno,s.Its great fun was thinking of bluing the second brno but I think i like it as it is . My shooting is done on my small 250 acre farm here in zimbabwe.Only crop protection. I look forward to hearing from all zkw 465 fans and more on the accuracy of nylon 66. Are open sights best on the hornets?
