I bought a Stoeger A30 .177 495fps from Canadian Tire because it seemed decent for the price and had a 3-9x40 scope. I’ve run about 150 pellets through it now, and I’m just confused by the spread.

I know that everybody says there’s a break in period during which it will be inconsistent, but I get the feeling that what I am seeing is worse than expected. Further, consistency doesn’t seem to be improving. The image shows four groupings:

  • target 23, 10, 1 (in order of firing, first two last night and 1 this morning): Stoeger
  • target 30: Marksman

These are ~1.5" squares, and I’m aiming for the center of each target. I am not a great shooter, I wouldn’t even say good - I just want to get rid of a rat in my backyard, and I haven’t shot in years. But I used my 20yo Marksman 1745 with a floppy barrel and a 4x20 scope I can barely see through, and I can get more accurate and better groupings.

These shots were taken at 11 yards. I’m using a camera tripod with a custom block on top to support the barrel of the Stoeger and the stock of the Marksman (as laying the barrel on it results in deflecting the barrel up about 8 MOA lol), and using a loose hold at the butt of the rifle. I’m a fidgety fucker that can’t stay still, but I’d say that I’m still enough at release with the Stoeger, considering the trigger is far smoother and lighter than the Marksman and I’m holding it farther from the supporting pivot point (both farther down the rifle and a longer rifle overall).

Another thing to note is that the scope that came with the Stoeger could not be mounted to it without shimming the rear mount up, as I immediately ran out of elevation adjustment. I used a couple layers of electrical tape, didn’t over tighten it, and have retightened it twice since as it settles in. It’s possible, but I don’t think that the scope is moving shot to shot.

It’s weird. I’ll have two of three shots that are somewhat consistent (down and to the right, for example), and then the next shot will be twice as far the opposite way, and the following shot up and the right. It just seems like too great of a spread for only 11 yards, even this early in the break in period. The box was semi-open when I bought it, but the rifle itself seemed untouched, so I also have some concern that somebody returned it and the rifle itself has an issue. Although I don’t know what that would be, because it looks mint, and oh boy is the pivot joint for the barrel ever tighter than the Marksman. I can move the Marksman barrel in all directions when closed, but the Stoeger is solid. Better be, considering it’s like twice the weight for the same claimed fps

final edit (I think) because it’s going to be too cold to continue soon:

  • this trigger is not a 'pull gently until it goes off" despite being a two stage smooth trigger — grip-and-pull alone decreases the spread by half for me

  • the spread on the non-defective model tightened up by 200 pellets

  • the variable scope may be slightly inaccurate at max zoom — backing off to half power results in lower spread (more testing needed to confirm)

    my latest round of shooting got me a 2in, 3in, 1in, and then back to 3in spread, all minimum 10 shots per target. only changes were some minor scope knob adjustments.

    it was looking good on the third target, with four or five pellets in the same hole, then I came back a short while later and got another crappy result.

    these four batches were with the hollow points, which are a tighter fit on the barrel, and some don’t actually go down into the barrel opening without force so I didn’t use them.

    I guess I’ll head in to grab some more pellets and a cleaning kit. I can at least say that after 500 shots, the grouping is definitely tighter than at first. but still very inconsistent

      With cleaning an airgun it’s recommended to only use the cloth patches lightly soaked in Ballistol, not the brass cleaning brushes. This is in order to keep the rifling factory sharp.

      It’s recommended to use a rotating cleaning rod on bearings, just allowing it to spin naturally as you’re pulling the patches through, to allow the patches to follow the rifling grooves.

      When cleaning, only pull the patches from the breech to the muzzle.

      Having started 3 months ago, I’m pretty new to airguns myself, so I’m just parroting barrel cleaning orthodoxy to you.

      Another idea is to read the reviews on Pyramyd to see what others have tried and what works or doesn’t work: https://www.pyramydair.com/product/stoeger-arms-a30-s2-air-rifle-combo?m=3643

      One user mentions “hold sensitivity” although they didn’t elaborate on exactly what that meant.

      Lots of complaints about the heavy 4lb trigger pull, which can also lead to inaccuracy.

      One guy mentions replacing the trigger and getting the pull down to 1lb and change.

      Some of the pellet comments mention JSB 18.13 gr pellets, which are .22 caliber, so they must have been playing with the .22 version of the A30, not the .177
