New pcp, when is it not good enough ?

[32:1]

OK, heres a question thats needs an answer as Ive been talking to a friend about a thread on another forum and we couldn't agree

With a new pcp rifle, what is unacceptable grouping at any given yardage and at what point does a manufacturer have to accept its no good and refund or replace, is there a given accuracy standard allready that has to be delivered by the said rifle as we buy rifles to hit things dont we, be it targets or vermin. Would the group size be considered the same for any pcp rifle

As a minimum for a hunting gun I would expect ten shots covered by a ten pence piece at 30 yards. That's rested, in perfect/indoor conditions with it's preferred pellet. I would expect more, but if it couldn't do that it would be going back.

Realistically I'd expect 10 shots within a 5p at 30m rested indoors - outdoor testing is harder to gauge, and you also have to give leeway for pellets and shooters skill - so there is a big variable that one shooter could have that another with a bit of time and patience could halve the group size of

I'm certain there is not an "industry standard", and I think you have to judge a £2k target rifle different from an S400 - although in good examples you may struggle to tell the difference - but the way the law works regarding "fit for purpose" is that it does take price for quality and performance into consideration - if you bought a Stoeger and came last in every bench rest comp you entered, then the law would say - that is probably what you should expect give the quality and price of the gun, and that would be acceptable for an average shooter.

I would expect a new PCP on a shooting rest, so no human interference, to shoot a single ragged hole something between 5p & 1p size on an indoor range at 25yds.

Agreed, although as said above, sub 12ft.lb (and in .177), I would expect that at 35 yards (but would maybe wear 25 or 30 yards if in .22).

I know what I’d expect as an acceptable group size at a given distance but I wonder what the various air rifle manufacturers would class as acceptable?

Perhaps I’m over critical of my equipment here, but in the “perfect” scenarios described I would expect at my zero ranges (which are 35yard for .177 and 30yard for .22 at 12ft/lbs) all shots in the same place. A PCP is recoiless and in its sweet spot should be more than capable of that consistency.

Any thing wild of the mark that couldn’t be put down to pellet performance or my user error (which is more than I care to admit ) wouldn’t sit well with me.

What place ... Selby?

This, sort of, except I would expect the ten shot grouping to be covered by a current British 1p piece at 35yards (my preferred zeroing distance), as my very basic, standard, single shot .177 BSA Scorpion PCP air rifle delivers. Fwiw, I also expect -- and recieve -- the same level of accuracy from my .177 Air Arms TX200HC springer, and would view any PCP which can not achieve this, as not being fit for purpose (and cr@p) ...
