    I had a cheap n cheerful Gamo (12 fpe) that loved Crosman pellets, and a more powerful Hunter 440 DX (18 fpe) that loved JSB Exact Heavy pellets. Trial and error is normally the way...

    I've heard people say that they will leave a new springer cocked overnight to bed in the spring. Never done it myself, but I do leave the gun locked & loaded for an hour or two when stalking. According to my chrony, this has not affected pellet velocity at all. Springs are tough.

    Nice shooting, bunnybuster. SAK silencers work a treat for the price, don't they?

    Finally caught up with the "coypu" I saw a few days ago -- and it turned out to be a Muskrat, which do just as much damage to the banks of lakes and canals in France. So I shot it. Check out Muskrat Mayhem #1 on my YouTube channel below, and if you like what you see, feel free to "like" the video and subscribe to the channel. http://www.youtube.com/user/keithnallen/videos

    Yesterday I saw the first coypu in nearly 12 months grazing on the lawn by our lake. Time to dust off the Zastava .22, and see if I can remember how the camcorder works. After I'd taken care of the live beastie, I found out why she was hanging around -- a monster male coypu that had drowned while trying to get under the fence that crosses the stream at the entrance to the lake. Check out "Coypu Caper #7: Two coypus for the price of one" at the address below, and don't forget to "like" and subscribe, to counter any antis who might not like what they see!

    .410 slugs are reasonably accurate out to about 25 metres, in my experience -- they're good for 3" groups at that range, which I've achieved at my pistol club under "perfect" conditions with a smooth bore. Wouldn't want to push them much further than that, so I'll stick to the rifle for vermin. If you're a registered shotgun owner, they're available over the counter at all good French gunshops!

    Had a Nitro Venom for a while in .177, 18fpe. Nice shooting rifle apart from the sh1te trigger. I modded the trigger by removing the spring behind the trigger that provides a false first stage, and by putting a washer over the roll bar that engages the sear. Trigger broke like glass after that, and the rifle was transformed. Your trigger kit will hopefully do the same.

    65 yards for me with Winchester and Lapua subsonics. Go the the link below and enter your sight height (vertical distance between the centreline of your barrel and the centreline of your scope tube). Then enter your preferred target size (one inch for a wabbit would be about right). Then enter the velocity of the round you're using (Win and Lapua subs come out of a 22" barrel at 1075 fps). I have a sight height of 1.5 inches and chose a target size of 2" (for coypus). Gives an "ideal" far zero of 65 yards, near zero 14 yards. Anything between 4 and 75 yards will be no more than 1" high

    Winchester Super X subsonics (40 grain, 1075 fps) through a silencer on a bolt-action rifle with a 22" barrel generate 102.67 fpe. CCI Blazers and Winchester Super X Hyperspeeds (40 grain, 1450 fps) generate 186.79 fpe. You would need to chrony specific ammo through your specific barrel to get a precise figure. Since 59 fpe delivered to centre mass will kill a human, I wouldn't worry too much about losing a few feet per second to cycling the action -- even 22LR subsonics are more than enough for most varminting needs

    I'd keep it if I were you, mate, especially with that sort of result! An accurate, quiet .22 is hard to beat in particular situations.

    I actually cleaned my HW97K's barrel today, on the offchance it would improve my groups. Made bûgger all difference, so I'll revert to my previous philosophy of never cleaning it! No powder, no residue, no point. If I do clean an air rifle barrel -- and when I do clean my 22LR -- I use a pull-through made of a length of strimmer wire (soft plastic) crimped with pliers in the middle to give it a point that will feed from the muzzle to the chamber. For patches I use 2cm squares of old tee-shirts. I soak the patches in Ballistol and pull through until clean, then pull through a couple of dry

    If Chairgun's a bit of a challenge, try the link below to find out your ideal zero ranges and min/max Point Blank Ranges for your rifle. http://www.shooterscalculator.com/point-blank-range.php Put in your pellet speed, the sight height (measured between the centreline of your barrel and the centreline of your scope tube) and your target size. If you put in a one-inch target size, then the calculator will show you the point blank ranges with no more than a half-inch holdover or holdunder. As an example, my HW97K spits out Weihrauch F&T Special pellets at 810 fps. So I enter 810f

    .357 magnum out to 25 metres. Does the job every time

    Keeping a springer cocked while hunting is something I do quite regularly (for stealth), often for an hour or several. My chrono results are still consistent after a couple of years of doing this. However, if you leave a springer cocked for long periods, you will suffer the consequences. Here's a test that some (presumably rich) shooter ran on various rifles: http://www.network54.com/Forum/79537/message/1009595055/How+long+do+you+keep+your+springer+cocked-+Here%27s+a+test- And here's a relevant quote from the PyramidAir blog in the US: "So how LONG does a mainspring LAST?

    The results are in! Just got back from England, after a cancelled ferry (doors wouldn't close), and dived out between the showers today to try out all the pellets I had ordered to be sent to my brother's house, following recommendations by shooters on this forum. To recap, I'd found that the best pellet so far in my untuned .177 13 fpe HW97K was the Weihrauch F&T Special (8.3 grains, 4.51mm). This was achieving 18mm groups at 33 yards. I had tried lots of other pellets, which didn't group as well: Bisley Magnums got down to 24mm CTC, but others didn't come close, including H&N Crow

    Very nice-looking rifle. Is that the factory finish, or did you refinish the wood yourself?

    BRC2 is great if you have a Hawke scope with one of their proprietary reticles. I use it myself. If you don't have a Hawke scope, you can use the following website to calculate ballistic trajectories, point-blank ranges, etc. http://www.shooterscalculator.com/

    Cheers Skot, thanks for that, interesting to know that it's not just me who found the 97K learning curve long and painstaking! I've ordered some JSB Exacts (4.51) along with five other pellet types, and I'll pick 'em up when I'm back in Blighty next week. I'll let you know how I get on, and I promise to practise, practise, practise!

    Logically, I would guess that less lead in the barrel = slightly less drag on the first round = slightly higher velocity = slightly higher trajectory, but not necessarily to left or right of zero. Different barrel/ammo combinations will no doubt react in different ways, so some shooters may see a difference after a clean, where others might not. I have to re-zero my .22LR after a clean, and I know other shooters of bigger calibres who need to fire fire a fouling round after a clean. Slipper also finds his first round through a clean barrel falls an inch above zero, so there's obviously

    And another variable... just ran some of the pretty consistent Weihrauch F&T Special pellets over my reloading scale, and found that they average 8.675 grains, but vary: six at 8.6, eight at 8.7, and two at 8.8. I even found one at 8.5 grains (and discarded it). I guess that accounts for some of them wandering off-centre by a few millimeters. If I were really anal about this, I suppose I could grade them all by weight and shoot only the same-weight pellets... but, frankly, life's too short, and over here in France they don't do HFT...!

    That could make a difference if it happened every session, I suppose, but it sounds like it only happens during the first session after he's cleaned the barrel.
  22. Coypu Hunter
    So, what's the explanation then, Obi-Wan?
  23. Coypu Hunter
    Care to enlighten us mere mortals, Obi-Wan?
  24. Coypu Hunter
    Many people do, but I don't see any rubbish in this thread -- just a bloke asking for advice and getting it.

    Hi Pianoman. Yes, that's the conclusion I'd come to, now that the rifle has settled down. Its initial twang has disappeared, and the recoil is smoother after a thousand pellets or so. I'll run it over the chrony later day to see where the power output has ended up. As you rightly point out, the trickiest part is maintaining the same level of pressure at the four touch points, shot after shot. The forestock hold is straightforward, now that I've found the rifle's sweet spot. I simply cradle the rifle in my hand, rather than gripping it, and my hand rests on a bean bag. Trigger hold is a
