This spring in a moment of weakness, the gunshop I frequent had what appeared to be a brand new CZ452 in 17 HMR. Now the owner knows my weakness and told me it was used with less than 200 rounds through it.
Ok says I, how much? I am a born again impulse buyer, so I guess that explains it. "$400 no tax, includeing rings and bases and I'll throw in a couple of boxes of different weight ammo to see what it likes". Well you know what is said about a fool and his money. To make a long story short, I ended up buying a mixed brick of the heaviest bullets available as well and $500+ lighter left eagerly for the bench at home to mount the scope, then the range.
To say the least, I was very pleasantly surprised with the accuracy. It had a problem shooting high and to the right when it warmed up a bit, so home again to free float the bbl in the channel and glass bed the action as well as lighten the trigger pull. Worked just fine next time out. The CZ452 in 17 HMR, unlike its sister in 22WMR, isn't fussy at all about what it shoots. They all go into nice tight groups out past 100yds with the lighter bullets shooting higher of course, but bullets of the same weight shooting to the same point of aim without scope changes between different brands. Very unusual, very impressive. Can't say the same about the 22WMR.
A few weeks later, I had the opportunity to test the two rifles together on gophers at varying ranges right out to 150yds. Prosper, you're dead on about wind haveing similar effects on both bullets, although very slightly less on the 22WMR.
The terminal performance on the gophers was a whole different story though. Especially at ranges over 50yds. Unless they were hit in the head with the 17HMR, they usually ran away, even though solidly hit in the chest area. On several of the animals that were inspected, the bullets failed to expand and both the entrance hole and the exit hole were almost invisible. So we switched over to Speer TNTs. They were a lot better but still didn't have the same catastrophic effect that the 22WMR had with Speer TNT rounds.
Overall I really like them both and would hate to have to choose which one to sell, but when hunting rabbits at ranges at and over 100yds, I would definitely use the 22WMR.
