What to do next on my fx impact m3

I'm contemplating making some changes to my FX Impact M3 (non-power block model), a .30 cal with a 700mm barrel. I have a 50-yard range set up on my property, with the option to extend it to 100 yards when I can keep the kids safely indoors. A friend recently provided me with a selection of NSA .30 cal slugs, after he found it cumbersome to switch between pellets and slugs. I'm eager to give them a try.
However, I've noticed from various online videos that the grouping of slugs at both 50 and 100 yards seems to be less impressive compared to the superb grouping I'm observing with .30 cal pellets. I would rather not push my Impact M3 to its limits just to make a certain setup work.
Interestingly, I came across a video by TedHoldover where he was able to achieve exceptional grouping with 1100 fps .22 cal slugs, which, based on my research, shouldn't necessarily be possible at that speed. As I primarily aim for precision on paper and knockdown targets at 50 and 100 yards rather than hunting (save for occasional pest control around the house), I'm looking for advice on how to proceed.
I have a few potential strategies in mind: (I realize i may need some upgrades if i go the slug route)
Converting to a .22 slug,
Converting to a .30 slug, or
Simply adding a barrel tensioner and maybe a power block.
I welcome your thoughts on these options. What would you suggest I do?

Which liner do you have? For slugs you need the superior heavy liner which has a different twist rate than the regular stx liner.

Just ask yourself, have I pooped my pants today? If the answer is no, you're doing okay.

Jon, my friend has an M3 .22 700mm and everything is stock, I've helped him tune it, great PCP. Depending on your budget, .22 slugs are much less costly to shoot than any .30 ammo! There is a lot of power in a standard M3 to sling slugs and still sip air. I have my RAW .22 tuned to shoot JSB 18gr pellets @ 970fps, JSB 25gr @ 870fps (just 3 clicks up for same POI) and NSA 17.5gr slugs @ 950fps (2 clicks up 2 clicks left for same POI) all on the same tune. You might just want to try lighter .30gr slugs first as POI shouldn't change dramatically unless you want to sling heavy slugs. Good luck and have fun!

Well, I'm not sure what is stock on the M3.

Maybe take a look at the .25 I have the Maverick in 700 mm The 25 gr jsb are tight at 50yd .I just set up 100 m target and I just started shooting that with the jsb heavy and javelin 34gr slugs. Slugs seem to group tighter at 100 but was pretty windy last few days.Ordered some lighter slugs want to see how they work out.
I shoot pellets or slugs just adjust power wheel for weight.
Think the jsb like 850-880 fps.
