Thread: Quick 300 WSM

Well we worked on that load in the 300 WSM yesterday between hunts and ran some rounds through my other Chrono and got different results from the other one. The loads were travelling at 3112 fps in my F1 chrono but in the Pro Chrono they averaged 2957 fps. We also went out to 400 yards and shot to measure the bullet drop which should have been about 17 inches which it was so we concluded that the chrono speed is correct. Today I ran the air rifle over both the Chrono's and found that the difference was about 20 fps bar one that was 47 fps different. The only thing that I can see that was causing the strange results was the pumice dust that was blasted over the chrono from the muzzle break, this could have disrupted the speed readings, other than that both Chrono's appear to be close to each other. Later on I will try some rounds from other rifles to see if there is a big difference.
The load of 69 grs RL 26 over the 200 gr ELDX that one of the members here ran over Quickload was pretty much bang on in the end. What ever way you look at it this load is a grunty one for the 300 WSM.
