I have a B22 and went thru the trigger issue a while back. That's about as far as the OEM trigger set will go. Here's what I've found ->
There are lots of threads here and on rimfirecentral and YT-vids on mods. I polished all the innerds of the B, anything that rubs anything, using 1000g wet/dry.
And then I heated the T-spring with a Bic, let it cool slowly. That got the pull down to about 1.4# and the polishing makes it smo-o-oth. I would NOT cut the spring unless you have a spare handy - too much and you're f-d. Alternative is the Varmint-spring from Gunshack for about $10 shipped. Or Apache for about $100 or Timney for $200. My solution cost about 1/2 hour of work. I think that's best and you get 'in touch' with your rifle.
Good luck

Here's one thread that I used a lot of tips from, but not all. I didn't cut any springs or drill anything.
