Nope, Nope, Nope.... I got work to do...

I'm gonna coil bind set that spring before I cut any more off.

Must be set. Coil bind didn't reduce it any to speak of..... Time to clip another coil.

Yeah, but look at that first number. A short barreled pcp pistol shooting 798fps. Pistol sales will soar! Until a guy gets it home and tries to sight it in. It took a year but that’s how the Bandit finally earned its black eye. It can be fixed, but we have to be happy with the velocity in which that occurs. It’s fun for some and a return label for others.

I’m gonna guess that when you get that first shot to be around 550fps, we are going to see a workable bell curve. But I won’t bet money on it. Just a hunch.

How about 666 and a workable bell?

Mind you.. that's a 10.49 Barracuda Hunter pellet.

2.5 to 3 coils off the spring.

avator · « **Reply #48 on:** January 31, 2021, 11:59:00 AM »

I kinda like a 10 to 13 fpe 20 shot .177 pistol.....

OK, call it 18 shots.... that's 2 full mags.

Would you go another half coil?

Pelletjunkie · « **Reply #50 on:** January 31, 2021, 12:14:40 PM »

That’s the million dollar question. Once you cut it off, it won’t grow back. Those 10 grainers are making use of the gun still being slightly overpowered. With such a small tube, I completely understand trying to work with a 3,000psi fill.

Pelletjunkie · « **Reply #51 on:** January 31, 2021, 12:16:44 PM »

This is when having 5 springs at your disposal comes in handy. Go too far? Oops, just grab another spring and keep testing.

avator · « **Reply #52 on:** January 31, 2021, 12:18:22 PM »

.... or shim.

I cut another half off.... we'll see. $:-\$

avator · « **Reply #53 on:** January 31, 2021, 12:30:19 PM »

Not much change but I think I'm at a threshold and I'm gonna leave it.

avator · « **Reply #54 on:** January 31, 2021, 12:33:34 PM »

I'm gonna do some accuracy shooting, find it's favorite food. If that turns out to be a big weight difference I'll check the numbers again.

Pelletjunkie · « **Reply #55 on:** January 31, 2021, 12:34:32 PM »

If you have time, let’s see a string with a 8.44 or 7.9. Something lighter. Let’s see what effects the pellet weight has on the curve.

avator · « **Reply #56 on:** January 31, 2021, 12:36:35 PM »

Got it.... hang tight....

avator · « **Reply #57 on:** January 31, 2021, 12:49:21 PM »

7.9 Crosman HP...

avator · « **Reply #58 on:** January 31, 2021, 12:49:50 PM »

That's a little hot.

Bill
Very nice string, I am following along......... I have been looking at one of those pistol/rifle combo's also.

I wonder if this will work in the Disco also?

3000psi fill down to approx psi??

Thanks,
Don
