Wolverine R walnut .177,,,,worth the wait.

Thanks for the comments guys.. .after running it through the chronograph I've determined this particular gun is shooting too hot and the groups thus far at distance show this. Average speed shooting 10.34 jsb heavies is 935fps or 20ft lbs. Also which I found strange is that the regularltor gauge is showing 170 on it....I think most 20ft lb guns shooting .177 are set up at 100 on the regulator pressure. Definitely need to get this speed dialed down to shoot better groups.
 
@kdog - Keith, I agree. I think its very interesting how accuracy can change dramatically with only small differences in speed. The Bantam that you sold me shot the 10.3s at 950 on High, and 920 on Medium (Low was around 800fps). You wouldn't think it makes that much difference, but it was half dollar sized groups at 50 yards at 950, and penny sized groups at 920. I found out (from some guys here on AGN) how to reduce the HST, lowered the speed to 895 on Medium, and now it gets dime sized groups at 50 yards with the JSB 10.3s.

170 seems super high, is the gage broken? Should be between 100 and 120 bar I would think...


 
Mike yes I'm trying the 13.4 and they are shooting good but with a occasional flyer...the monsters are shooting at 830fps...still a little hot. This reg gauge went down to 150 bar but now I'm asking myself why it is fluctuating. Even at 150 I think that's still way to to high...I agree with you I think it should be more in the neighborhood of 100-120. Hopefully there is a easy way to adjust this but after taking the stock off it I don't think so. Waiting to here back from AOA on this.
