PCP Hold

PCP's do require a firm grip, especially the more FPE output there is, without question. Few reasons likely why...PCP's are far more powerful than springers. PCP's have more UP recoil where springers have more back/forward recoil. Also piston/ram type valve systems are much heavier and robust in that they generate good power themselves by functioning hence the back/forward recoil of a springer. Where as pcp's use a hammer style/ knock open valve 90% of the time which ultimately operates fairly eloquently in comparison. JMO

Indeed, it’s one of those things that varies from rifle to rifle. While it’s true that PCPs are not hold-sensitive compared to spring piston guns, most do exhibit some preference as to how tightly/loosely they’re held, as well as where they’re held. The higher its power and the greater its recoil, the easier it is to notice, whereas a full-size .177 rifle set to a modest 10-12fpe may exhibit no detectable preference once you factor in all the other more significant sources of error.

I have noticed a change in poi with regard to how i hold my Impact (tight or loose)

Yup I've found this to be very true. Exactly as Matt said also the more power/bigger the caliber the more apparent it is. 

I've found .22s in the 20-45fpe range to be easy to shoot consistently well. But the higher you get it's alittle more sensitive. 

Jump up to .25 and you'll notice it even more. Then go to .30 and it's a big difference compared to a .22! Not that it's hard but does take more concentration.

Follow through is very important as well. If your putting any side pressure on the gun. When shooting out to 100yds it's very showing. I was shooting my .30 WARP and some shots would be off a inch or 2 from the rest of the group and couldn't figure it out. Then I paid attention to my follow through and I was putting pressure on one side and even though was dead on when I pulled the trigger my aim would move to the side a few inches from the recoil and the pressure I put on the side of the gun. As soon as I corrected this then shoot a 5 shot sub MOA group at 100yds with 4 being within about .5".

All things considered I've now gone down to only .22cal guns due to the ease of shooting and lack of need for the bigger calibers anyways. 

Noticed in my FX Indy, as the pressure and velocity drops, the point of impact at 25 yards will rise. Guessing it's because the muzzle has slightly more time to climb whilst the projectile is dilly-dallying on its journey. Also noticed that shift is lessened if I'm holding the gun down firmly on sandbags.

So, yes, that's one example I've found where PCP holds for a PCP can play a role.

I have an Impact and a Leshiy and I notice the lighter gun in particular needs a firm consistent hold. It is extremely accurate if you are careful about this. I assume it is because it is such a light gun. The impact still needs to be planted firmly against my should and a good cheek weld and it is deadly accurate well past 50 yards. Hold it loose and the groups widen up.

Hey guys I am curious as to what you have found in hold with full size rifles compared to bull pups

I have noticed the same holds true with the impact. I thought my groups at 100 yards were a little loose. I changed to a snugger hold and the groups tightened up.

I hold the same for all my guns rather it be my streamline, daystate, impact, R5m, cricket. What I have to concentrate on is the trigger pull, I sometimes get anxious when pulling the trigger that's when the groups open up or I miss my target (game).

Curious if you guys can hold your sight picture throughout the shot cycle. 

All guns move during firing. Some more than others. Your POI consistency is a product of the consistency of your gun support. This includes grip as well. Whatever method you the shooter uses must be always be the same, then you simply adjust the sights to the POI. This is especially true with pistols, but it applies to all guns.

Thats a big no on the retaining sight picture at least when zoomed in, at 1-6x you can probably get away with it. That or if your rifles fully clamped or held SUPER gorilla tight by shooter..

I hold my pcp rifles like I hold my firearms and that gives the best accuracy and the most consistency in the accuracy or precision in other terms.

Thank you for the comments guys. Appreciate it a lot
