There will be another level of learning once you have a butthook/plate: I recommend not changing the weight balance until you're using a plate/hook because:

 

a) this will automatically move the centre of balance further back

b) the front heaviness that remains will lock you in for positional shots.

 

One thing I did notice is that your action is still quite buzzy and loud. Shoot a thousand or two pellets through it to settle it in, or import a tune kit, or both. That will help.

 

Sporter:

 

Target:

 

Ian is no longer falling over backwards trying to get in behind the scope.

 

His back leg is not tucked under his front, causing him to collapse away to the right. Nor is his front hand pulling on his leg to find support, which tenses all those left arm and back muscles.

 

His neck is not as craned.

 

His overall position is more upright, and (you can't see but they're there) his weight is through legs, allowing himself to act as a tripod.

 

Still a few things to work on but look at the improvement in a 4-week period!

 

The score reflects it too.
