🌟I HAVE ACHIEVED RELIABLE 13 YARD Mark IV ACCURACY WITH JSB RS FROM A REST🌟
Beeman 7.7 wadcutters look ok. I had a tin to work on after running out of RS. Centering the sight on the middle of the pop can works off hand at 6 to 8 yards.
The Mark IV can really shoot well once you get to 200 shots. Some pros, who dive into econo break barrels, believe it takes 500 shots to achieve adequate budget gun accuracy.
Considering I'm not quite yet to 500 shots (I was polishing off tins of Econs and RS) I hope that is a great truism! But I'm happy with this Umarex break barrel RIGHT NOW!
Here is mod video if you are determined to try and lighten the trigger pull. This gent makes clear it is MORE THAN JUST A SPRING SWAP! More work needs to be done, more problems addressed. Walnut and Steel did nice work:

I personally think it is also VERY BASIC piston sear/piston engagement. A touch rigid.
Here are great pellet choices:
