Not uncommon at all. I have 2 rifles that do the same thing, one is a .22-250 and the other is a .308, both are off by over 350 fps.

The .22-250 was an eye opener, should have been somewhere around 3800 fps and it showed just over 3400 fps.

One thing in common is both are shooting Varget and I believe the batch I have is running slower then normal.

But, other things effect speed too like the case volume and bearing surface of bullets.

In my case I upped the charge of Varget and got to where I should be. The load I use in both these rifles is listed in a Lyman manual too. This is one of the reasons I try to look at as much data as I can get my hands on when deciding on a load.
