.177 farmyard hunting....

Hi Rhys,

I found the Polymag shorts and Baracuda Hunter Extreme to be accurate in my HW100 and the DS Mk3 that I recently parted with.

Give me a shout if you want some to try.

That's a good offer.. you about Thursday?

I'll be at work but, you're welcome to pop in for a cuppa mate.

I'll bring the pellets in with me.

I like flat heads. I don't believe that the extra shock makes any difference to a clean kill but the extra energy dumped (a considerable amount) means less over penetration and so less ricochet.
I will have some at the bash which you are welcome to try

Yep, and I had much success back in the day for close range farmyard duties with the good old Hobby. Ideal at short range as it sheds energy quickly and is very soft.

Talking of being able to drop power for short range duties (and I'm not talking boingers, shock, horror), this would be a fantastic remit for a quality multi-pump wouldn't it?

That doesnt make sense to me. If you have a pellet that has 10FPE in it and it drill thruogh then only a proportion of the potential.has been imparted. If its a flat or an HP and it doesnt drill through then all of that energy is imparted to the target.

Flat heads are generally a paper puncher pellet so the mass may not be present as in say an HP. But 10 FPE is 10 FPE. Cross sectional density and argualbly the softness or hardness may contribute to efficient transfer of that energy.

Either wauly....if itndoesnt groupmor makenthe distance then the most effective pellet on paper spec.9s uselezs if it cant hit the spot at the distance you need

I have to agree with FF, sub-12 ft/lb air rifles don't kill by dumping energy into the quarry - there's so little of it to begin with. They kill by destroying vital tissue. A pellet that passes through a creature's brain will actually cause more trauma than one that stops short.
Wadcutters, such as Hobby, can be devastating against fur - the flat face causes more trauma - but aren't so hot against feather, as they tend to featherball quite badly, which retards penetration and can prevent the pellet reaching the heart on a body shot...

I found that the .22 sniper lites (domes) did this.. dragged a whole bunch of feathers 3/4 of the way through the animal.. I almost think it causes more damage as the wound canal was bigger than when it didn't bind.

Not just the case with sub-12 airguns.

Militaries typically used retained energy at distance as a measure of lethality. But that isn't a perfect measure of lethality. It's a way of setting a baseline specification. They also require things like penetrating a given amount of body armour/steel helmet (as was) at a given distance.

Add all those up, and other things like trajectory, and you have a requirement that must be met to qualify for consideration. The round must penetrate this thing at distance A, carry this ft-lbs to distance B, and stay with X inches of trajectory between distance X and distance Y. And group into Z at distance P.

Same applies in wound ballistics. Different projectiles with similar energy can have markedly different effects on a biological target.

Wound ballisticians do not talk about "energy transfer" or "knock-down power" or "stopping power". They talk about wound ballistics. The one thing they all agree on is that shot placement is critical to outcomes.

IL do that thanks!
