I currently have two Savage 17HMR's, one is a model 93 HB SS lam. thumbhole stock model the other is the A17 Target Sporter Laminate. My A17 will consistently out shoot my model 93, but, not until I spent a few hours messaging the trigger assembly in my A17 because right out of the box, it was absolutely terrible. I bought my A17 right when Savage came out with the Target Sporter model so maybe, at least I sure hope they are, better now.
Remember, regardless of what the box/label says all 17HMR ammo is made by CCI or Winchester with CCI making the vast majority of it. I think the only two labels the Winchester stuff comes in is Winchester and Browning.
I've shot cases of 17HMR ammo over the years in multiple different Sav. 93/17HMR's and two Ruger 77/17HMR's one with factory barrel the other with Lilja barrel and for me the CCI made stuff, in particular the 17gr Vmax ammo, has consistently shot the best. The Winchester/Browning stuff just doesn't shoot as well for me so I tend to stay away from it.
Keep in mind, all, 17HMR ammo is what I'd call hunting grade only and is far from match grade like you can get for the 22LR's so this stuff can vary, sometimes a lot, from box to box. A lesson I learned the hard way a long time ago with shooting 17HMR's, always re-check zero when you're changing Lot #'s even if it's the same brand/label ammo.
If I were in the market for a new 17HMR bolt gun the CZ 457 would most likely be at the top of my list. I've heard good things about the Tikka and a few others but the CZ's have always been pretty good and they also have really good aftermarket support as well.
