Does this equal accuracy or catastrophes. I have been testing and testing my cricket from 21 grains to 45 grains. It seems as though, the pellets don't do so well at higher speeds as well as the middle class pellets do. I thought I had found a pellet that really liked my barrel, the first five shots at 45 yds was right on point. Up there if not better then jsb's but after the first five it all fell apart. Pellets started going all over the place. I went from one raged hole to 11/2" grouping. I really was scratching my head on this one. 25.4 grns. To 31.0 grns. I'm not sure what I did different, so back to square one. What do you guys think? My gun is throwing these pellets out at around 975 fps. Best Steve
Heaver pellets at higher speeds .25 cal.

Typically, 850-900fps is the fastest many recommend to shoot pellets. Some guns will shoot well above 900fps but not all.

The pellets I believe you are having difficulty with are the 25.4 JSB King and 31.02 gr H&N Barracuda correct? I can't see how you are shooting both of these at the same velocity as the JSB King is.a 25.4 gr with a BC of .0360 whereas the heavier 31.02 gr H&N Barracuda has a BC of .0420 and is 5.62 grains heavier.
In any case, it sounds like you have a chronograph so you should be able to find a pellet that shoots in the 860-880 fps range which should in theory, yield the best results. Other than having to resort to a heavier pellet, you might want to try having your Cricket adjusted so it isn't shooting so hot. I believe Crickets can easily be adjusted by adjusting a screw but am not certain.
If you haven't already used them, get yourself a tin of the 35.8 gr Eun Jin domed pellets and see how they shoot out of your Cricket. Some rifles do really well with them.
Good luck!

I took delivery on a .25 cal Cricket about 3 weeks ago. It chronyed at 915-20 fps. I would get some good groups for 3-5 shots and then fall apart. This morning I turned the speed down to 875 fps with the JSB kings...and walla!! 1/2" 5 shot groups at 50 yds.........Ernest Rowe was a great help as I was getting discouraged.

Mine shoots at 942 and does quite good with the older JSB pellets. 10 shot 1/2 groups at 55 yards is doable. I have a hard time with the 2014 pellets with the new thicker skirts. I have tried the 31g kodiak pellets and are doing quite well too. I have a older tin with a different model number on tin which doesn't shoot as good as the newer ones I bought the other day. Most 25 cal crickets do quite good in the 900-925 mark. Play around with your speeds and see what you come up with.

Depends on barrels and guns, I know for a fact that the TJ .250 barrel shoots the Benjamin dome @ 1000 fps with extreme accuracy

Sorry Scott, I should have been much more specific, my bad. I was originally shooting this gun at a speed of 975 fps w/JSB's I turned it down a bit worried I might of been pushing it to far. I tried to talk to Ernest with little luck. I reached out with several emails and he finally answered back and said he would call, but I never got that call. Anyway, so I tried to turn the gun down With just the hammer spring. It must of worked because the JSB 25.4 works really well. However, it did at the higher speed as well. 50 yds and I get a 3/8 hole pretty consistent. Then, I decided to see if there were heaver pellets that I could get the same accuracy out of and I would get a little more knock down power at longer ranges. So I set out to do just that. The ones in question, were the 31.02 Kodiak match. I really thought I had a winner. But after that first five. I cleaned my barrel with a pellet cleaner by Beeman, shot it out and and kept going on. Then I proceeded to shoot a ten shoot group with jsb's. Had no problems, loaded the gun with the kodiak's, first shot, money. second shot ok, I may have pulled it. Third shot went an inch in the opposite direction. Know I started scratching my skull. And so on, that's how my day went. Of course because I cleaned the barrel it could be that. But then why get the great accuracy from jsb's.

Steve, sometimes when switching pellets, you need to shoot some of the new stuff through the bore, before it will come around. I tend to shoot 20 to 30 of the new fodder before worrying about what size the groups are. Also, with so many variations available in the kodiak's (barracudas) I generally find that I get better results with the ones that are not the "match". May be a different head size like 5.52 vs 5.53 in the regular, but I generally see better groups and save money over ordering the match.
