    So I bought my Maxxim as a package deal and it came with Diablo Field 16 Grain domed pellets. I sighted it in with these and they are very consistent. Problem is everything else I have tried is all over the place. 

    1. Crosman Premier Hollow Point 14.3 grain

    2. Benjamin Hollow point 14.3 grain  These look identical to the Crosman

    3. Ruger SuperPoint not sure the weight on these.

     

    All 3 of these don't even hit close to where the Diablo's do. Any suggestions. The Crosman are readily available at Walmart for cheap. Should I just try and sight it in with the Crosman's and leave it at that? If the gun is even consistent with those. I have probably shot close to 400 rounds with the gun.

     

    Thanks for any input. Oh, I'm also using a BugBuster scope.

    No rifle will shoot all pellets well. The trick is finding one that groups well and it seems that you have. There may be others but that requires testing.

    Heavier pellets will not fly as fast – and may be better for accuracy.  Stay below 950 FPS or so, as a ballpark benchmark.

     

    And you are right – the Benjamin pellets are re-boxed Crosman pellets.

    I have been going threw this as well. I shoot H&N 14.66 gr. at 60f to 100f they shot good. After 100f  they were all over the place. I opened a new tin yesterday and the pellets fit real tight putting them in. It was 85f this morning I was shooting my 40 yd target dead on. It is 113f out there now, they are dropping about an 1.5 in. but they are not all over the place. Same pellet different batch can effect your POI at longer ranges.

    I'm shooting at 20 yards. I may try and see if I can get the Crosman's to hold a pattern since they are so cheap and available locally. If not, I will probably just order more of the Diabolo pellets. I never would have thought different pellets would act so different. 

     

    Thanks guys

    I got the Swarm in .22 also.  To get the best accuracy: clean the barrel well, take it a part, clean and tighten all bolts/screws, then use a hard allow pellets (since the barrel is rough and chews them up).  I got mine from 6" groups at 50 to 1.5-2" at 50 by doing this.  Predator GTO's are best with my maxxium. The more powerful version (magnum), will work with something copper coated like Baracuda Power 21gr.

    Looks like Tractor Supply sells a Domed Crosman, although lighter than the Diabolo I may try it. I'm thinking the gun doesn't like the lighter pellets or it doesn't like hollow points.. If it shoots a good group with the Diabolo I'm not sure it's a gun issue. I have shot a cleaning pellet through it but that's all I have done as far as cleaning. I'm shooting this at 20 yards with the Diabolo Field made by Air Arms.
