Don't try this with your QB78, folks.

Of course, you would never load two pellets into your QB78 air rifle, close the bolt and fire. But, oops! that’s exactly what I did recently when performing a Gold Service test on a QB78. My excuse is that I was distracted by a telephone call in between shots...

Anyhow, I had fired eight pellets with this .22 caliber QB78. The muzzle velocity was in the 500 - 510fps range for these shots and then - all of a sudden - there was a 290fps reading. WTF?????

So, I looked at the target and you can see the results below. I had double-loaded this QB78 and the gun fired both pellets at once. The result was the 290fps reading from the Chrony and the impact of two pellets about 1 1/2-inches below the impact point of the main group.


So, that’s what happens when you double load a QB78 family air rifle and fire it by mistake...
