I just bought an air rifle hand made from surabaya, indonesia. and i need comments for this.
Sorry i haven't a photo yet, soon i will post the picture of my rifle.
My rifle Spec :
* CANON Cal. 177 it's just exactly look a like Benjamin Franklin.
* Hand pumping

Thank's

Sounds good -how many F.P.S.?

Ah I remember these .. you can pump many times ( as much as your hand can do it) and the more you pump the faster the pellets seems to travel.
However, I remember, they have a terminal velocity of about 350fps or so.

You can make it go faster if you have heavier hammer spring (so it press on the release nipple longer and release more air onto the chamber).
But the expense is a heavier trigger because there is no detached sear.
Nice!! Used to hunt rats near Jakarta with them back when horses bites steel days (Indonesian term "kuda gigit besi")

Do you have one with rifling on them or smooth bore ones?
"barrel nya ulir atau tidak?"

ulirnya ada Tpi bentuknya spt bekas bor-an ada 8 jalur.

In the website it says about 750 fps

Ulirnya ada tapi kelihatan seperti bekas bor-an, ada 8 jalur.
