T"#1 Will the 60 work with sub-sonic ammo?"
Yes and no. Please refer to my thread - See "Basket Case's Latest Test" (that's the rifle's name, btw) here http://www.rimfirecentral.com/forums/showthread.php?t=225093. I didn't note exactly which was and wasn't fully cycling, looking for accuracy that day.
"#2 Has anyone had any luck with the open sights?"
Yes, years ago, Glenfield M-60 + CCI Mini-Mags + a little luck = good groups for me. These days, if it's past five feet, l likely have a scope...LOL
YOU SOUND LIKE ME,
I CAN'T SEE NO-GOOD EITHER
THANK GOD, FOR VARIBLE SCOPES!!!!!!!!!!!!
