I have only worked on a couple of .25 caliber Bams, but they will achieve 60 FPE. At that power, they are real air hogs. If you take the power down to 50FPE or below, you should be able to double the shot count. There are a few ways to drop power on the B-50/51. Smaller transfer port, extend the hammer screw, lighter spring, lighter hammer, shortening the spring, and less air pressure. The hammer screw is the cheapest alternative, followed by a smaller transfer port. When you get a chance, check inside the hammer, under the spring guide. On occasion, I have added a washer or two to create extra power. It added weight to the hammer and a bit of pre-load to the hammer spring. If the washers are there, removing them will reduce power somewhat. To lighten the hammer, I take out the steel spring guide and add a Delrin guide. Another tuner drilled the guide out with a 5/8 drill to reduce weight. Either option will work. I would prefer not to do anything that was ir-reverseable if possible. To me, the lighter hammer spring, for that caliber, is not the best option. If you fill to 3000 psi, there is a chance of valve lock because the lighter spring can't overcome the pressure holding the valve closed. Cutting a coil or two off the spring is a better alternative. Less air pressure will result in less shots, along with less power.
For straightening the trigger, the heat will allow for easier bending, but when it cools it will be brittle and harder. Non-ferrous metals need the opposite treatment from steels. Steel will harden when cooled in water, and get soft if air cooled. Brass is the opposite. It will harden if air cooled.
Yes, I'm back.
