About as much as anyone should ever hope to get out of the 9x19mm. Someone please correct me.

    With pleasure.

    The Sterling Patchett Mk5 Silenced SMG (L34A1) was, according to Sterling, even more accurate than the standard Mk4.

    The silenced Mk5s had to group a maximum of 2.5 x 2.5 inches at 100 feet and 7.5 x 7.5 inches at 100 yards. With standard ammo.

    I really doubt that the standard Mk4 guns would have to group about half that at 200 metres.

    No cartridge is inaccurate rifles are
    Ie 7.62x39 sks's are pretty inaccurate but other bolt action rifles can be very accurate

    The problem with the .22RF is the design has not changed much since 1852 the case has got longer but the basic design has kept the heeled bullet which
    is why it will never be capable of top accuracy no matter how accurate the rifle it is handicapped by the ammo,
    the .22 RF Magnum should have fixed the problem but for some reason it hasn't, I have shot the .22mag bullets in a .22 Hornet and a .222 Rem both
    shoot it better than the .22mag so it is not the bullet

    @shooternz, Well, that does not strictly speaking follow. Your .22mag bullet was shot through a different set of barrels than its native .22mag barrel.

    Maybe someone should start shooting paper patched .22mag reloads. Let me see, first reloading item required would be a pair of +3.5 dioptre reading glasses from The Warehouse.

    @shooternz

    Would be an interesting experiment... (-: I'm currently too occupied trying to perfect my technique for castrating mosquitoes with only a sharp hypodermic needle, and wearing boxing gloves of course.

    But seriously, I do wonder if there is untapped accuracy potential in the humble .22LR/Mag with paper patching. After all, it does eliminate lead/copper fouling.

    The 22 Hornet has a reputation as being tempremental, thin neck on the case. They can shoot very well but?
    (Anyone shooting Bruno or CZ will disagree)
    Savage 22 Hi-Power. Again these day's the rifles are old and limited range of projectiles in 228.

    Re 22 mag
    Shop around for ammo. Mine did 9 rounds into 1.5: at 100 mtr with Remington 33 gr or Hornady 30 gr.
    or 4" groups with 3 shots of 40 gr CCI.

    Modern shooters a spoilt back in the 50' 60's and 70's any rifle that could shoot 4 MOA was considered adequate for general hunting,
    there were some accurate .303's built on P14 actions what stuffed them up was shooting cordite loaded military surplus ammo through them
    only took a couple of those to start eroding the throat, if you find a new .303 barrel don't shoot military ammo through it ,
    My old 2 groove No4 would shoot 1.5 MOA with the right bullet even though it had been shot with surplus ammo,
    nothing wrong with the cartridge just the use of the wrong powder

    The .303 cartridge isn't inherently inaccurate but the LE action/two-piece stock/bedding system is what lets it down in reality. And the hot-burning powder/corrosive primers certainly weren't great for barrel life. All in all, a very bad combo for longer term accuracy, especially if you weren't fastidious in your cleaning

    I also nearly gave up on .22 mag until I tried the 30 grain hornady. Keeping an eye out for some more of it.
