I have to agree with bobtod and Rico.
Between work and all the springtime chores, I have pretty much zero time off to shoot long range.
Luckily for me, I have a 100y range down in the pasture.
I have a lot of neighbors, so the sheriff gets called if there's too much high velocity ammo getting fired. So far, it's been all friendly with the nice quiet match ammo.
Being exhausted most evenings, I find myself sneaking down to the range and shooting a lot more groups from prone than usual. I haven't had time to drive the hour to shoot centerfire on BLM land, and it's hard as eff to practice silhouette with jelly legs and chainsaw forearms.
Let me first say, my CZ 455pt shot pretty crappy when it was brand new. Around 200 rounds, it started to show some promise.
Somewhere between 600-900 rounds, things were looking good. Then it wigged out around 1200 rounds, due to a buildup of Wolf/Lapua woo on the crown.
Here's a pic of the day it wigged. After shooting the targets noted "after 200" I noticed the crown, it had a big barnacle of bullet lube crusted on the crown. A dry boresnaking and it shot the remaining groups on that page
100y
The bottom page was first groups of the day, not shooting so well, plus a few groups of 6.5. We will not discuss the circled group of 6.5
To clean it, I used a dry .17 cal snake @ 500 rounds.
A dry .22 snake @ roughly 900 rounds
Again at 1200
A .17 or .22 snaking every 1000 or so, usually I use the .17 and give the crown a little tlc with a q-tip.
A more recent pic at around 6k rounds. there's been quite a bit of wind lately(15-20mph), this must have been a less windy day. I am really not good at making wind calls
I Cerakoted the stock trigger and lightened it to its max. since the 1st pic. It's no Jewell or Timney, but it's good enough I don't really feel the need for a YoDave.

my measurements seemed a bit rough upon reinvestigation, the inner orange ring is 1".
And some 10 shotters with some decent wind. The group with no target, it was dead calm at the end of the day. I dialed .7 mil(I think) and held the center bull(I'm pretty sure I was chasing a bad first shot for better #'s on that target
)
Shot #7 was the wide left, poor recoil management, as was shot #9 on the wide right. Inner green rings are 1"

The fifteen shot group was from another day, again, at the end of the day. It was dead calm for the 1st 10. I took a shit with the sandbag around shot #4 for that 1 that hit high.
10 shots measured around mid .8's if memory serves me(don't count on it) and around .65ish without my crapper shot.
I figured I'd shoot the last 5 rounds I had at it. Then the wind picked back up............. I hit the 3 low and the 2nd highest shot with only 1 good shot out of 5
All groups were shot with Center-x with a Champion bipod(POS, my Harris Finally got here) and rear bag.
When it was new, I tested about 12 different offerings from Eley,Federal,Remington,wolf,SK, and Lapua. I did NOT have any Tenex.
Lapua Midas+ was best, followed by center-X, the higher end federal,SK and Eley were pretty close, but I was seeing a few flyers.
Wolf MT and ME(match extra) suck ass at 100 and beyond for ME.....best I've ever managed is 1.25" @ 100y. At 200y it gets 10 times worse in the wind. For some reason, it hates the wind
I'm very happy with the way my stock CZ is shooting.
The less I clean it, the better it seems to get.
I'm just waiting for the day it all falls to hell and I have to scrub it and start all over again. Saving that damn Wolf for that.
Now I just need to learn to shoot better in the wind, that goddamn shit is EVERYWHERE.
Something I found interesting: I had to download and print the manual for my buddies new Anschutz. I'm pretty sure it said clean every 1000 rounds for the first 2000 rounds, then clean every 2k-5k rounds. It's on their site as DLC
