Xisico b28 m not grouping

How much springer experience do you have? Most feel they nee3d a certain hold, and you do need every finger ... in the same exact sport everytime.
Also, that scope is too great, could it or the mounts be an issue?
Heavy pellets for certain! The 1 I tried out ( M28 from Mike) was shooting 23fpe in .177, but it grouped well at 40 yards.

And, just waht size is " wont group" ?

Magnum springers are an animal that takes some time to tame. Especially if your new to the game. One thing on the B28 is the stock screws loosening up quite often and another thing to check is the breach seal O ring on those China guns. Archer sells shim kits or I've heard of people using dental floss as a shim behind the O ring to better seal it to the breach block. 
Also need to try different holds while shooting. Don't grip the gun like a regular rifle just let it kinda float and don't pull it tight to your shoulder. Oh and one other thing you definitely need to get a better scope than that Barska... that gun is a scope killer especially the cheap ones.
I had one in .25 cal that I tuned to 30fpe.
and it shot great as long as I did my part.

hope you figure it out...
