Looking for suggestions...
I picked up a .22 Dreamline Classic a few weeks ago. Primarily I wanted this rifle for low power work - somewhere around 12ft/lbs is what I'm aiming for. Straight out of the box (after cleaning the barrel) it was shooting 15.89gr Hades at around 610fps set to low. This was a touch pokier than I'd have liked ideally, but it was consistent and grouping well, so I left it. Next time I shot the the thing, I couldn't get a group for the life of me. At 30 yards, indoors, I was lucky if I was getting 1.5 inch groups.
At full power, it groups pretty well with both Hades and the 18.1s.
I spoke to a few people who suggested that at lower velocities, a lighter pellet would stabilise more readily. So I ordered a tin of 13.4s, and have shot it at pretty much every velocity from 500 - 710, with a huge range of different hammer spring and reg settings. Each time, it's stupidly consistent over the chronograph, but downrange performance is abject. With shroud removed, it's tighter - but I'm getting flyers at least every 4th shot. Interestingly, when I put the shroud back on, the POI shifts about 10-12" higher at 30 yards.
Knowing that there's been some issues with barrel rigidity, I've made enquiries about a barrel band, but that doesn't explain why it's performing well at full power - if the barrel were the issue, I'd expect similar inconsistencies.
There must be a sweet spot for low power shooting. These rifles are sold in markets where energy is restricted by law, and if they're were performing like this in those markets, we'd be hearing about it! Any suggestions would be really welcome.
Thank you!
