A couple of weeks ago, I picked up a cz 455 suppressor ready synthetic stock and a cz527 fs in 223. After installing scpoes on both, had to go to the indoor range a half hour away and sight em in. Started with the 455. Sighted it in at 50 yds. Shot 5 rounds of cci sv for group at 50 yds. To my surprise, 5 rounds just a little bigger than the bullet itself. Was using a 4.5x16 primary arms ffp mil /mil scope. I figured out the dots for 25, 75 and 100 yds. The 527 shot little bug hole groups at 100 yds with myhandloads. I have a Nikon m223 4x16 bdc on the 527. Feeling really satisfied, I went to the counter to pay up for the range time and they were unpacking today's shipment from big brown. Looked over and they were checking in a sp01 tactical. I've been looking for one for a long time and it followed me home. Great day today. I love it when a plan comes together.
