PCP's....kick?

Muzzle stability can be improved with a silencer fitted but in the case in question, Weihrauch silencers are very light. I found my accuracy improved, shooting an S400C with a 'heavy' Logun silencer fitted, because muzzle movement was slower and less jumpy with the extra weight at the front. Regards .... Geek

ok with my 57ft/lb shooting 31grain barracudas, recoil is felt. my groups are much better when i hold the gun snug and fit rather than light recoil and i use a small sand bag underneath the butt. what happens when i shoot long distances is usually this and i know right away that i called the shot incorrectly. When i squeeze the trigger the reticle jumps and does not return to the original Point of Aim thus i mark it on the logbook as an incorrect shot. in these cases the reticle usually returns to place where the pellet has hit further showing that the shot was not taken properly.

As soon as i squeeze the trigger the rifle butt moves slowly backwards and downwards since the stock is slanting thus sometimes i do throw one or two shots above the group that had formed so nicely. i regret that i never had a stock made with a flat butt like those used on F class because the slanting stock is not good enough for the precision i try for and when you do everything perfect, you read the wind, you dial the correct elevation, recheck the distance and then blow your shot high because of this, it is definately frustrating. i might get a monopod to sort this problem out really that waythe gun would notmove downwards.

Newton's Third Law of Motion (every action has an equal and opposite reaction) applies to precharged air rifles as it does to everything else. The reason you don't feel it at low power levels is that it is so small. it is related to the energy in the pellet so as pellets get heavier and MV gets faster the effects begin to be noticed. In .22 I notice it around 40 ft lb with 21.4grain Bismags. In .25 I certainly notice 31 grain Baracudas being spat out of the rifle at 55 ft lb. In .177 the only time you would notice it would be when using very heavy pellets at 30+ ft lb.

you certainly can feel it at lower power... I can notice the recoil of my 6ft/lb 2002 vs a 6ft/lb steyr fitted with a recoil damper...12 ft/lb rigs are noticably more jumpy in comparison, even the so-called dead ones

My .22 FAC HW100T kicks a little more than the standard UK version.

I've closely compared the "view-through-the-scope" rat hunting videos posted on YouTube by a guy called "snypercat" (you can look these up - worth seeing). I know that he is UK based.

I cannot quite match his steadiness during shot release with my own HW100T rifle. I get a noticeable (albeit very small) jolt whenever I pull the trigger.

My rifle is putting out about 25-29 ft/lbs - his is below 12 ft/lbs.

It makes perfect sense if you think about it - Newton was right

I'd imagine that his groups are slightly tighter too.

This could mean the centre of balance of your rifle is too far to the rear, depending how you hold and shoot it and in what posture, in certain circumstances. Or perhaps your grip or trigger technique could be modified. You sometimes see F.T. shooters have added weight to the front of their rifles. I've added weight to the rear of my EV2, to redress the balance. Just a few thoughts, not saying you're necessarily at fault, or your mate. Regards .... Geek

I've never had any recoil effect on my HW100, I just thought PCPs suffered a little muzzle flip & that's it. Fair enough my HW100 is running at legal limit velocity but if this is the case, surely there would have been some effect. If your rifle is running at getting on rimfire velocity like an FAC Career 707 (80 ft/lbs) then that could be plausible. Still, stranger things have happened. Having said that, if your HW100 is running at FAC velocities, the muzzle flip would be much harsher & the effect of the muzzle rising when the pellet exits the barrel, could give the illusion of recoil. I'd still like to know how that works out though, I love anything technical.

Clever fellow that Newton! However, I'm surprised that you notice anything at the power levels of your HW100. As far as my experience goes, any .22 air rifle under 30 ft lb feels totally inert. If I miss it is because I am not holding the rifle correctly or my breathing isn't under control not because of recoil. For me to notice the Newtonian third law effect, as I wrote in an earlier post, the power needs to be 40 ft lb-ish in .22 and its equivalent in other calibres otherwise the recoil is too small to notice. Even then it is very small. How many of us regard recoil as an issue when using .22LR or 17HMR?
I suspect very few.

I have a .22 FX Gladiator set at 12fpe

If free standing very little recoil is felt but if the gun is bench rested their is a noticable jump which is due to the hammer spring rather than general recoil.

So if one could come up with a solution to generate a equal reaction EG: a Wiscomb two springs moving in opposit direction one would have a very accurate rifle.

Over to you Ben Tayor

PS The daystate mk3 i have tried had no recoil EG: electronic trigger.

At 12 ft/lb it os more likely to be jetting causing a small push from the muzzel blast. Can feel it on my P70 Ft and that weighs 14 lb.
