I'd imagine that a bi pod would be the go for a pistol.
Yep 80m is unrealistic for a pistol, was more about fpe drop, but the bc supprised me. I wasn't expecting a same weight pellet to gain that much just on bc. |

If I was to make one that had the crosman stock on it, I would make a bigger tank, which would allow more shots at the higher power. But of course nothing wrong with making a bigger tank for the pistol. If I was hunting with it, i'd be resting it against something to steady it anyway.
But how many shots are you going to get with a pistol when hunting rabbits? They seem to get plenty in the UK with sub 12 fpe, so 13/15 fpe should be adequate, but challenging. I wouldn't be taking 80 m shots with a pistol, it'd be a gamble. Yea I might try the 362 barrel on it. That had crossed my mind. |

Not by much though.
Running it out to 80m it's only about 1 to 2ft/lb approx,depending on bc Jsb hades 15.89gr 632fps = 14.1 ft/lb Bc of 0.023 6ft/lb at 80m Jsb exact jumbo 15.89gr 632fps = 14.1 ft/lb Bc of 0.031 7.5 ft/lb at 80m Jsb match Diablo exact heavy 18.13gr 580fps = 13.59 ft/lb Bc of 0.035 8.75ft/lb at 80m. 80m may be a bit to far but I went for the 5fpe approx to kill a rabbit, on worst bc, and who knows what the finished gun with a standard 22xx clip on stock may be capable of. But it definitely sits well in the range of useful power for hunting. Being it's a 22xx breach you should pop the barrel off your 362 and see what sort of gains you get.

I shot 3 strings tonight. It's very interesting seeing what the numbers say.
First string using 15.89 grn JSB with the hammer adjuster wound in 2 turns ![]() Next Using 18.13 grn JSB hammer on same setting ![]() then 18.13 grn JSB with hammer wound in 4 turns ![]() So what I see is that the heavier pellets get better power out of the gun. There's no benefit filling it to a higher pressure with this valve/hammer set up, and that I think maybe 1 to 1.5 turns will be a good setting putting out around 13 fpe for more amount of usable shots. At 4 turns it was shooting around 17 fpe for the first 5 shots, which is good power I reckon, but just not the air capacity for many shots. Overall I am really pleased with how it's turned out, as it is good enough as a hunter if you can stalk and shoot a pistol well.

It'll give you time to design it on your head.
I really want to make a breech, but am still mulling over how to tackle it. We could combine design. Would that make it a Punga? |
