Cutting coils is not a recommended solution. If the rifle were mine, I would buy a Timney after market trigger to fix the problem. They are easily installed.
If you want to lighten the existing trigger pull, the school solution is to grind some of the steel off the outside circumference of the spring, which will lower the spring rate of the coil, thereby lowerning the pull weight. I use a belt grinder with the platen in the vertical position and grind carefully. Use a good 120 grit belt. I put the coil on a punch, with the punch tip angled up so the spring coil doesn't fly off during grinding. I keep a cup of water handy to dip the coil in so the temper isn't removed from the coil. It's a do a little at a time and try proposition as you don't want to grind too much metal off the coil.
Polish all mating trigger part surfaces too, then lube with a molly paste. You can get that trigger pull down this way. I've done it.
