hi folks,just opinions on what hv rounds would be best in a cz 457 .22 for 100 yard bunnies,i know every rifle likes different ammo,or should i just use subsonic,or is 100 yards asking too much for a .22?thanks...its a 16 inch barrel

100 yards is a bit far in my opinion. It is do-able but you have to be very good at judging distance and working out bullet drop. 

Id say 75 yards is a good limit to set yourself and always had my sights set for 45 yards. With plenty of practice you can get good at adjusting your aim accordingly. Practice is the key, it always surprised me just how much difference that actually makes and easy to get out of practice.

As for bullets, I would stick to the subsonics that suit your gun best. Try the most common ones and go from there, no point finding the ones that suit best can only be purchased from the one shop that sells them which rarely has them in stock and only opens while you are at work. Even at longer ranges I always found the subs were much more accurate than the higher velocity rounds. Only thing HV's are good for is making lots of noise imo.

100%. 
Except I always zero my .22 at 60 yards. I think most probably use 50 yards. 45, I think, is a little close.

I lost interest in LR when SK stopped their subsonic hollow points. Fortunately, there was HMR and Remington. Rabbits do us a favour with an on board range finder and bullet drop calculator provided we can remember a few figures.

This 👆 100% 

I set mine up at around 50 yds and shot a bun at said distance. When I thwacked him another sat up alot further away. I ran the reticle up to the top of his ears and squeezed the trigger volleying one at him and bowling him over. 80 large paces later I picked him up. I was quite pleased. I leave HV's for making some noise having a bang up with my Beretta semi auto.

I use Winchester subsonics in my CZ452 which I find are excellent. I also use various HV ammunition (mainly Blaser) in my S&W M&P 15-22 semi auto, although it will cycle the subs. With the CZ, I have set the zero at 40 yards as this is the approx distance where I shoot most of the rabbits. 

100 yards for HV is not too far, and I have used these in my CZ.

stick with subs, at 100 yard HV will be coming back trough the sound barrier so will give a nasty crack and can be a bit more unpredictable accuracy wise off the back of it. a rough calculator shows a 40gr 22 sub doing 1050fps at the muzzle will still be doing 900 at 100 yards and that means its hitting with about 70-70 ft/ibs of energy.  even at 400 yard the 22 sub is still pushing 40 ft/ibs, so energy isnt really a factor for rabbits for 22lr

Yep SK subs were superb in my Finnfire (better by a country mile than anything else).

We did a lot of testing for subs and HV up to 100 yards. For us mere mortals 75 yards was the distance that we could get decent groups and surprisingly both had a similar drop. I think the HB’s speed scrubs off a lot quicker , hence the drop.

There's always a rack of variables that affect the accuracy.  1.  Firstly is the individual shooters ability  2 The built in accuracy of the gun / barrel  3 The compatibility of the ammo to the barrel.  Personally I zero at 30 paces and get the gun on then its out to 50 paces for fine tuning. The trajectory with 22lr really drops after zero at 50 paces. I can regularly nock rabbits over at 80 paces by giving a bit of vertical allowance but it is a small target at 100 when you have gestimate the distance and drop.  The bullet has more tĥan enough impact power  at longer range but target accuracy is a bit of a fluke.

I did pest control for 13 years on US air fields with a .22 and only used Eley standard and zeroed at 70yds and regularly head shot rabbits out to 100yds.

 The reason I used Eley standard, first they aren’t much louder than subs, and when hitting a rabbit in the head, which is where I aimed for, they made less noise than subsonic. I zeroed in at 70yds with the Eley and when I tried some subsonic ammo for comparison it was 6” low. On one occasion I set to shoot rabbits at 175yds and if I remember correctly it was 32 clicks up and I head shot the rabbits, my gun club chairman was a witness.

 And finally I was using 14 to 16 thousand rounds a year, they were cheap
