I bought my 527 used from a CZ forum member almost a month ago. Yesterday, BIL and I headed out for some Varmint Hunting, so I got to spend some time with my new gun. I haven't got a chance to take it to the range where I could sit down, bench it, and really take time. I need to do that still. This gun did pretty good from the "roof of my car bench wrest". I needed to make sure it was sighted in. So we set up a quick 100 yard range and fired a few rounds.

I shot Winchester 45 grain Varmint HP's. They shot very well out of that gun. I know that I will be able to get better groups from this gun at the "real" range with a decent wrest. Still I am very happy with it. Watch out for that set trigger! Wow that trigger is light 8)

Then we went Varmint hunting and the gun really proved it's worth. I took several Jack Rabbits at over 200 yards.

They sure are awesome guns aren't they? If you get into handloading, I've got some recipes for my 527 Varmint that are just plain amazing.

Here's mine btw:

Going to Miles City in June for some dogs with my CZ Varmint. What are those loads. Any experiance with Ramshot?
 
I have not used Ramshot, with all my loads I seat the bullet .020" off the lands and use win brass and federal small rifle primers:
Nosler 50g Balistic tips: 24.0 grains H335
Sierra 50g Blitzkings: 26.0 grains H335
Sierra 52g Matchkings: 26.9 grains H335
Hornady 55g V-Max: 27.0 grains H335

The most accurate load is the Nosler (.328" 5-shots), followed by the Blitzkings (.332" 5-shots), Matchking (.468" 5-shots) and V-max (.60" 5-shots). BUT, The Matchkings are the most accurate so far out to 300 yards at 1/2 MOA (~1/5") The Noslers are my lightest load and kind of run out of steam that far out and drop almost twice as much as the blitz and matchkings.
 
The cartridges in this group were loaded on a Dillon RL550, the powder charge was dispensed by the Dillon powder measure, not weighed, the only preparation on the brass was trimming to length and swaging the primer pocket of the military brass. The rifle was a bull barrel AR15 with 1-8 twist.

John, I think I saw your group some where else and it got me to thinking about my next varmint gun. I have a couple of ARs in the safe. I may build an upper in either Tac .20 or .204 Ruger. I guess I have not ruled out just using a .223 though. Problem with the .223 is I would need to shoot a very light bullet, .40 gr V-Max, to get the velocity I want. I am afraid it would run out of gas too soon.
The 40 gr .20 has a BC of .275. One has to get over 60 gr. in .22 to get that type of BC.
 
Bought CZ American , beginning of last winter. Put 4x scope on it and took it to range with box of Win 45 gn varmit loads. While sighting in off sandbags, first 3 shot group at 100 yds was 3/8 inch. Got all exited and fell on butt on the icy range , after checking target. After range sight in, cleaned it and NO copper showed up using Barnes copper cleaner.

Would like to have lower scope mounting, anyone try any of the medium height rings now available? Believe Leapold and Burris now offer them?

H-335 is about the easiest powder to meter. I'm not using a progressive, but once I get the charge set in my RCBS powder measure it will not deviate by more than 1/10th of a grain. I check every 10 rounds to make sure it's still throwing the right charge and it's almost never needed adjustment.

I want to use my Dillon to charge, seat and crimp. I,ll give 335 a try.

Have you experianced any cartridge feeding problems out of the 527?
 
H335 flows beautifully out of a Dillon powder measure, I found it to work very well in 223 loads.

It was kind of funny, I tried H335 in my 22-250, my rifle didn't like that load at all, it didn't group...it patterned like a shotgun, I didn't measure it but it must have been 5-6" at 100 yds! :uhoh:
 
No feeding problems. I have noticed that if I am shooting loads that have been neck sized a few times that they are a little stiffer to load. However, if I give a little pressure on the back of the bolt with my thumb as I push the bolt forward it seats fine. Full length resized or brand new cases feed like a dream though, we're talking REALLY smooth.
