John, if you haven't yet try the JSB 15.89 and 18.13's I think you'll like the results.
Scott, mine is shooting Baracuda 21.14s at 875. All I have done is to add two regular washers(thicker that the ones in the gun) turned the brass disk that is between the air tube and shroud half a turn counter clock wise. If you degass it turns easily with a small Allen key. Just stick the short end in a hole and tap lightly. Pull it out and do again about 4 times.I only fill to 3200 and shoot to 2000.
T oday was the first time I have put more than a few pellets down the bore. I filled mine t o 4350 and it started off around 780fps with JSB 18s, climbing pretty quickly to 870, and settling to the high 850s for the bulk of the fill. Second fill was to 4000 which helped some, but still had a curve. Anything I can do to help this, or will time, and shots help? I only added 2 thin washers to the hammer spring, would another 1 or 2 help?Only shot CPs, JSB 15.8s, and JSB 18.1s. The 18.1s seemed to shoot the best.One of my mags malfunctioned, and basically isn't springloaded at all. Guess I will see if I can fix it.
The regs do settle in, a lighter or under / over size pellet can give some of the sporadic readings.
It will show processing until it is delivered.
Especially when shooting Crosman premier domes, 6 will group pretty good and 4 more will fly all over the place. I would have loved to of seen the Liberty shoot them as well as it does JSB's.
Quick question for those of you who ordered your Liberty from ATI: how did they notify you when it shipped? I ordered mine last Thursday on their website. My status still shows "processing" but I checked my credit card and they've already processed my payment. Do they normally send out an email with a tracking number?
Funny you should say that, my first group with CPs was 5 in one hole, and I thought I didn't even need to try other pellets. I was surprised that I was unable to duplicate that group, or even come close.
