bulk fill experiences?

[LRair]

Looking for practical experience from those that have converted from 12 G powerlets to bulk fill on Crosman 150.
I have the conversion fixture extended endcap and the siphon tube Co2 tank. but is it worth it from a shot count standpoint?
Thank you in advance

I did it decades ago and in my opinion it wasn't worth the trouble. Think I got fewer shots from a bulk fill anyway.

I still bulk fill a couple guns that have more chamber capacity, though.

Pretty much same here. Cartridges are cheap at Walmart. Yeah, I got fewer shots too. Only gun I still have bulked is a Crosman 622 that I modded the trigger on (much better). That one does get more shots per fill because now it fills the whole tube. I made the adapter to seal the tube. Fun plinker!
The 150 is great the way it comes. I shoot mine a lot on the first click. Many more shots and still rolls the cans
Do this trigger mod. Add a set screw behind the trigger guard . Eliminates most of the creep.

I came up with an over-travel adjusting screw trick for 150/112 grip-frames back in the late 1980s. Now Crosman has adopted it on their excellent PCP pistols. Enlarge the photo in my attachment below to see my approach.

I also invented a trick to install a sear-engagement screw on the 150/112 grip-frame that, combined with a lighter trigger/sear spring and a little moly lube yields crisp, creep-free trigger breaks of less than 2 pounds (and sometimes one pound). When scoped with mounts I sold for decades, a healthy 150 shoots 1/2" groups at 25 yards, with power enough for small-game and pest hunting.

My first Crosman 150 opened my eyes in a big way back then, and continues to amaze me still. Here's why-
