I am not familiar with the Williams sight. A 6.5X55 has been a want for a while. I have an as new #1 RSI in 7x57 that I really don't need and have considered rebarreling that to 250 Savage.
I have a couple of mannlicher stocked 6.5x55s, a factory built Husqvarna 1640 HVA and a Ruger 77 parts gun, a 77 R MK2 barreled action in a 77 RSI MK2 stock.
The Husqvarna has a longer barrel, so it balances and points a little better than the Ruger, but the Ruger isn't half bad, still 100x better than a CZ 550 FS.
