I have played around with .22 rimfires from a very young age! Have built, owned and played around with most of the ctr-fires over the last 25 odd yrs. Also re-built lots of .22LR's. & converted a good nr of .22 mags into .17HMR. over the years! Actually; one of the very first that I converted/re-built into .17HMR while living back in NZ, was my very own single shot Anschutz 54-.22LR Match rifle, wich previous owner had put a 'ring' in the factory brl's bore! This was even a couple of months before the very first .17HMR ammo had hit the shores of our country!
I played around with this one for a while, trying to convince myself that ammo prices would come down shortly and performance was way better then .22LR? Well it never did and it wasn't! Actual fact was that prices seemed to go up every year! Sure; it proofed to be an amazingly accurate and flat-shooting round that handled the smallest of critters well with the Shilen Select Match tube fitted; however its sheer lack of 'real' improved performance on small game was duly lacking, when compared to its little brother with any of the Win. 'Subsonic'/Power-points or HV-HP rounds?
*For example: while shooting rabits, hares, possums, walibies & magpies on private farm-properties in NZ and the opportunity presented itself: try killing Red Deer & Wild Pigs with a single shot from the .17HMR; yeah right, unless you can get close enough & put em trough the eye-socket? Well, no problem whatsoever with any of the 40gr.-.22LR/HP slug mate! In the end I couldn't justify leaving my .22lr's back in the gunsafe any longer, so I traded it back for a nice Kauri stocked Lothar Walther .22LR Match! Then I moved to Canada and got 'hooked' on gophers!. Lucky me, that I still own this Lothar Walther .22LR Match 'Running Boar/Sihouette Rifle" and when fed with either 36gr. or 40 gr. Winchester X-pert .22LR-HV/HP ammo, it can achieve amazingly accurate & deadly hits everytime. Some at amazing Ctr-fire range distances under min. wind-speed conditions! Even a couple of friends of mine seem to have a very hard time every year, trying to copy these distant hits with their Rugers 77, Marlins, Savages & Brno's in .17HMR cal's! *So really: I still ask myself were all the fuss was about? There is still nothing viable out there in between the .22LR & any of the ctr.-fire rounds, that would justify an early retirement for any of my .22 Rimfire rifles! For this gopher-season, I think I'll be starting out shooting an HW77-.22cal. pellet rifle for the shorter ranges, where the gophers are thick & plentyfull, followed up with my custom Ruger 10/22HB for the medium ranges! Later in the season I'll be taking my newly re-built Ruger 77/22 along; fitted with a Anschutz 54 Match brl. (treaded receiver/brl-fitting off-course) for the longer ranges!
Maybe it will be 'on-par' with my Lothar Walther? Sounds sweet to me: I'm already starting to feel that itch coming back to me and will be looking forward to the upcoming gopher-season mate!
