There is no joule limit in my country or in my field. Shooting with rifles under 20 meters is prohibited.M170 should be using .45 or heavier, you have the fps.
Does depend on barrel length you use, the long 410mm is about right for .45.
Do you have a joule limit in your country or the field you play at?
Many thanks for the information. You really saved me from a big mess.I recommend .45-.49g, they'll give you the best range and accuracy.
That spring fatigue thing is ridiculous, BB weight has nothing to do with that, but leaving you gun cocked for hours does.
For stuff to prepare your rifle, wrap the middle of the piston in copper or lead wire and then tape to get it to 50-65g, and then put it back in your gun.
This will alter your pressure spike and allow you to show heavy BBs more easily.
Yeah heavier is almost always better, especially at high energy. I wrap mine in solder and then put a few layers of electrical tape to hold it on. At about 60g, it increases .48g bb joule output relatively substantially.
do fps rings work for weight? Or air brake pins. I'm afraid of damaging the piston while doing this.Just read THIS, it'll be a better help
it was very enlightening. I am gratefulJust read THIS, it'll be a better help
ok thank you very muchFps rings work, but they dont add weight. They basixally jusy make the spring under more tension (like getting a bigger spring). Heavier pistons sre more efficient.
