Title: Powderless 22lr ammo in CZ452 military training rifle
Post by: Fast Eddie on May 04, 2017, 04:19:13 PM: Zeroed a new 452 with a Burris/Banner model 4736 scope at 75 ft balls on.
3/4 in groups after 25 shots and adjustment with stand. velocity ammo and 40 gr lead bullet.

Then:
Switched to Powder-less/22lr at 25 ft.
Impacts were 1.5 in low and 1" to the right.

Is that to be expected?
I can understand low, but to the right?

Would that be due to twist? hold/grip/trigger? Coriolis force?????

Any ideas?

Post by: bestins on May 08, 2017, 12:44:07 PM: you may want to try a subsonic round like a cci quiet--theyre not as quiet as what you're shooting but are much quieter then supersonic rounds. I use them for squirrel hunting/dont scare the squirrels as bad.
