My local range has a benchrest group that competes once a month. Some pretty good shooters there. I recently got a new CZ 527 Varmint in 223 for the purpose of 100 yard target shooting. Today was the first time that I shot out to 100 yards (really only fooled around sighing in my 6-18X scope until now).
Twist is 1:9
I had 4 types of ammo.
#1- Cheap Russian Tula ammo, 55 grain. FMJ
#2- Hornady Match HPBT, 52 gr. over 24gr of H335
#3- Hornady V-Max 40 grain, moly over 24gr of H335
#4- Midway 'el cheapo' 55 grain FMJ bullet over 24gr of H335
Results....
@50 YARDS
#1 - 2.5"groups, #2 - 1.5" groups, #3 - 2" groups
@100 YARDS
#4 - 2.4" groups, #2 - 3.125" groups, #1 - 4" groups
The 50 yard results are probably only of minor interest as the BR club shoots 100 yards always.
Not sure what to do to get closer to 1 MOA (1")....? More powder, less powder, other bullets...? Surprising that the cheap 55 grain Midway bullets did best at 100 yards....
PS The trigger shouldn't be the problem as the CZ has a 'set trigger' feature where it is pushed ahead and just a couple ounces of pull will fire it.
