I only use the super lube on o-rings and silicone shock oil 740 on my pcp pump o-rings and internals..this was posted a while back 👉👉https://www.airgunnation.com/threads/do-not-use-superlube-grease-for-pcp-handpump.33450/
I've used those when I was bulk filling 88 gm co2 bottles I refill then switch to HPA then I found this twist on/off asa. I prefer the twist on for it disengages the pin from the bottle so no pressure in between not like the other one. My output is set to 1100 psi.
Breaking in is usually for the shooter. Getting used to the air gun, how she wants to be held then choosing the right pellet for it after you've done familiar with your AG.
Spend a bit more for the 2240 XL which comes with steel breech and treaded tip for a moderator, it will come up cheaper in the end. > https://www.pyramydair.com/product/crosman-2240xl-co2-air-pistol-22-cal-steel-breech?m=5117
