Anschutz sporting rifles have long been known for their accuracy. This model fitted with a Cabela’s 6-20X scope is a real tack driver.
The Remington 504 is a highly regarded entry in the field of rimfire sporters.
Frequently, someone writing either in an advertisement or an article mentions using the 22 WMR or 17 HMR for hunting small game. Either will certainly dispatch small game species, but head shots better be made if you want much left to eat. These high velocity rounds are explosive to small targets, especially at the ranges at which squirrels and rabbits are normally taken. The primary use of these magnum calibers is in taking larger species or taking small species at long range where their higher power and flatter trajectory are advantageous. Rabbits, squirrels, and treed raccoons do not require the use of a magnum rimfire. There is one advantage of the 22 WMR over the 17 HMR for small game hunting. Although the overall case length is shorter, the old cartridge known as the 22 Winchester Rim Fire (WRF) has almost identical head size and body taper as does the 22 WMR. Therefore, it is perfectly safe to fire 22 WRF ammunition in a rifle chambered for the 22 WMR. Because it is a specialty item having low sales volume, the cost of 22 WRF ammunition is about the same as it is for some of the lower cost (not premium) 22 WMR ammunition. The advantage of using the 22 WRF cartridges is that they feature a 45-grain bullet with a muzzle velocity of around 1,300 ft/sec so they are similar in power to a 22 LR high velocity round. This can be important when using a rifle chambered for the 22 WMR on edible game. The only factor to consider is whether the slightly shorter 22 WRF round is sufficiently accurate in your 22 WMR to justify its use. In my bolt-action Ruger 77/22M, the CCI 22 WRF gives outstanding accuracy. Five-shot groups average just over 0.6 inches at 50 yards so this gives me the flexibility to use ammunition of lower power in my 22 WMR without sacrificing accuracy. However, I must sight in with the 22 WRF ammunition because the point of impact at 50 yards is 5 or 6 inches lower than where the 22 WMR hits. The 17 HMR offers no such lower-powered option in ammunition.
