Rules for FAC air rifles.

[billy_boyle_2010]

FAC runs at around 850-925 fps for Diablo pellets, after that they become unstable.

Let me put it another way a pellet of the same mass will decelerate more hitting a solid object if it is travelling at a higher velocity. That deceleration is the energy transfer as that kinetic energy has only gone into the animal, nowhere else.

I’ve recovered plenty of pellets that have expanded well, the bigger the bone the better expansion.

I get the feeling you have zero experience with FAC air or what it is capable of, so you are working on assumptions based on what you have seen with your own sub 12.

I’ve shot thousands of rats and rabbits with both sub 12 and FAC air rifle. The FAC is a better tool for the job every day of the week provided there’s nothing behind that can get damaged.

Absolutely I haven't used FAC air- pretty sure i said that above

I also totally agree that FAC is the better tool. But how much better does it need to be for rats ? Other than the texas shot- or v large long chicken sheds- I'm not sure. If I did tonnes of ratting I prob would though!

Interesting point re the deceleration- it would be interesting if someone had calculated it but I shall take your word for it

Long had an urge to get an HW80 on ticket - .22 or .25. Springer simplicity and a nice flat trajectory with a big thump out to 40-50 yards max.

You did, but the comment on the speeds was really what I was getting at, FAC is a real step up. I go ratting with a couple of colleagues, both use sub 12s, the difference in terminal effects is very, very obvious. The 30is ft-lb vs the 12 means you are not waiting for that perfect presentation of a very small kill area. As I said way back, you aim pretty much where you want as long as the vitals are behind which ever part of the body you’re aiming at, the pellet will get through and the rat will be dead. It means you’re a lot quicker on targets, not waiting for them to stand in a shootable position etc.

The deceleration would be an interesting thing to measure, but aside from putting a chrono the other side of some dead rat carcasses and shooting them, can’t see how you’d measure it- the terminal effect however, speaks for itself.

@25 Sharps

Yup agreed and interesting. A 30 ft lb ratter in 22 or 25 would be nice to try!

Would a .25 springer get you more range though ? I couldn't shoot a springer accurately enough to benefit from the extra power personally. Although by all accounts they shoot better at fac power levels.
