Tried the Kodiak 21.14 grain in my Discovery & ...

They shot really good. The groups were tight as tight as the JSB Exact Jumbo 18.13 grains.
I could tell the velocity has dropped off. I will shoot them over my Chrony soon after I feel better.

Also, I have fixed my problem of the with the bolt jumping up allowing air to leave the barrel when I shot. This problem also allowed more noise even with the TKO, but putting a rubber band on the bolt handle resolved both issues for me. I have to admit that I do shoot the air rifle several hundred times a week. So I am sure some maintenance is due earlier than most owners.

Well. That is all I have for today, and safe shooting.

I have several air rifles that really like the kodiak pellets, Disco being one of them. If the speed of the pellet matters more to you than the size of the group they make, your using the wrong pellet though.

On your bolt jump problem, are you using a muzzle device of some sort?

Yes, I mention the TKO 5.5" muzzle break in my post. Is that a common problem? It is quiet now really quiet since the bolt stays down. I am thinking of taking the TKO off because I really like how short the Disco is without it. I know it is loud, but I really don't care.

Not sure how common it is but I have never read of folks needing a rubber band to keep the bolt down without a muzzle device installed.
