I have been playing with a friends 22/250 over the past week doing a bit of load development etc. I have observed some surprising results regarding bullet drop.
I have been using 50gr V-Max's and 55gr NBT's with both Benchmark and Varget. Velocity has been measured by a Chrono 10 feet in front of the muzzle. Various loads displayed velocities between 3500 and 3700 FPS, with quite big extreme spreads ( around 100FPS ). Using the classic 1" high at 100yards, I would have expected to be bang on at 200 yards given the velocity. In reality, using a 1" high zero, POA at 200 yards was a full 2" low. I had to adjust POA at 100 yards to a full 2" high to get a 200 yard Zero.
I hear a lot of chat about flat shooting 22 CF's etc, and holding dead on out to near 300 yards. These actual observed results would tend to call a lot of these claims into question.
Any comments lads??
