[QUOTE="Buzzdraw, post: 1666477, member: 385"] The .22LR does have a good bit of bullet drop. From some data I used for NRA Rimfire Silhouettes, with a 44 yd zero it took 2.25" up for 66 yds, another 2" up for 79 yds and another 6.5" up for rams at 109 yds. The preceding data was for CCI Blue Label (Standard Velocity). The .22LR cartridge, being lubed the way it is, is very subject to accuracy degradation in high temps. Summer temps, like in a car or worse yet a car trunk, would cause groups to double in size. Cold temps caused no degrading; we often transported our ammo in a small cooler with a cold pack in the hot months. [/QUOTE]
