The springer doesn't have a brake - it would be interesting to see each gun with and without a brake to compare.
Very interesting videos, though. |

That's what happens. You have that spring moving. Much more power I think. PCP guns release power from a stored unit. Springers have to compensate for loss of energy to friction, the gun itself (movement) and much more.
Didn't think that it would be that much vibration though. I suppose that's why bull barrels are supposedly more accurate? |

broommaster2000 That was a very informative video. Thanks. I suppose if I want something extremely stable,good for longer shots, I should consider a PCP. Springers are nice, but hard to keep on target at longer range. |

Charles, thats not entirely true, its all about technique. shooting a springer requires a different hold from almost anything else, and once you have it down, you can hit just about any target at just about any range (within reason) |

Great videos, although I still wonder what a muzzle brake might do to dampen harmonics on the springer. It does show without a doubt that there is a lot of vibration going on - and anything that alters those patterns will influence accuracy (like a rigid bipod, hand position, "hold," etc.). Still, I do use a bipod with my springers. It's a cheap Ram Line plastic job that I cut down:
Maybe it's precisely because it is cheap and flimsy that it works (i.e., it wobbles enough to accomodate the gun's vibrations). I clamp it on the barrel right next to the breech block.
Today was the first dead calm that I've shot in this year, so I did a little experimenting. This is all with my G1, (3-9)X32AO Crosman Scope, Crosman Ultra-Magnum 10.5 grain domed pellets, at 100 yards, from a bench, into fibre board. Here's a five-shot group with the Ram Line bipod:
And a five-shot group from a sandbag rest (supported at the gun's center of mass):
The bipod is a little less accurate, but still a fair trade-off for the convenience. The bipod did, however, raise the P.O.I. - by about 10 inches at that range. |

Yeah, I noticed. I still want an HW90 though.
I've been thinking lately. I need a spring powered sledgehammer. I wish I had a high speed camera.
The whole bipod story isn't necessarily trough. I use my Diana 48 from a Bi-pod a lot, and it get's reasonable groups. The bipod is attached to the stock. |

Good thought, so I checked. No discernable play, and I can feel drag through the whole return arc after cocking. It's more probable that the hinge problem is in that pointy thing growing out of my hand. A little twitch at 100 yards can make a difference.
Or maybe cosmic rays, or a sudden gust of wind, or that cute blonde that rolled in just as I released the shot. Don't I wish.
The shot I find interesting is in the "no bipod" group (the grey pellet outline). It would have keyholed had it retained enough gumption to penetrate the fibre board. |
