Long time ago I seen this before but cant remember the answer,,
Why can I shoot 177 pellets faster and accurate than 22 pellets, or 25 caliber, Now I have not done a lot of experimenting with 25 pellets.
Now I am not going into detail of brands weights and all, But I can ease my 177 to 980 to 1000 fps and still shoot good groups at 48 yards,
My 22 start giving me groups like a shot gun going past the 920 FPS range,
Don't even bring the slugs in, Please, I shoot pellet guns.

What pellets and what gun? Know what barrel is in your gun? .177 is flatter shooting than a .22 and .25, but I've hsd the opposite encounter from you using pellets. Over 890fps and they scatter unless it's the barracuda powers or the barracudas

Bigger pellet less aerodynamic maybe, probably has a lot to do with pellet shape/B.C.
I used to have a .177 Career pcp back around the yr 2000 and it was super accurate with the brown box Crosman Heavies at like 980-990 fps, killed a lot of starlings off a 100 yd power line at a hog farm I used to do pest control at. You couldnt get any closer because they could see you and left.

I got my pants put on me by a noobie years ago. He was having issues with a Taipan .177 and that’s what attracted my attention to the topic. Rare as hen’s teeth. He said his best results were with a super light pellet in warp drive. I said no way you should be shooting that fast, slow it down. He claimed it got worse. So I grabbed my Lelya .177 that was set for 10.3’s around 900fps. I loaded a mag of 8.4‘s and blistered a full mag group the size of a dime at 50 yards. Logged back into the forum wearing my a$$ for a hat and apologized.

No rime or reason to this sport sometimes, Getting off 177 a little bit, I got some JTS 22 caliber wadcutters that like 900 FPS in my Prophet #2 at 50 yards ,
Pellet on pellet, No wind of course, The sound of wadcutters hitting a sparrow is gross, Make you laugh out loud,

the semiwad or the wadcutters? I tried their wadcutters around 815 with good results , didnt try faster due to being wadcutters.

I miss my .177 taipan. Mine liked shooting all pellets but the ones that surprised me were the hornets going around 930fps and still under half an inch at 50yds with no wind.

48yds? What happens when you print groups at 60yds? 70yds?

On my fast 22Cal Impact I shoot Hades/Atomics at ~950fps right now. It does amazing out to about 60yds then opens up with pellets veering off randomly. I think if you were to try for groups further than your current distance you would find that the pellets still dont like to be pushed fast. A slower ~850fps pellet can print great groups much further than a faster speed.

If there is a difference between 177 and other Cals I would be interested to learn why. From what I understand the limits are due to the backwards design of pellets in general; with little improvements depending on specific designs. But they all want to flip around backwards or spiral or take a hard 90* right turn etc.

My previous evanix rainstorms in .177 would blister crossman piranhas very accurately to 50yds, they were smokin at 1150fps, beyond that ,they were garbage lol. 16g beast 950fps were moa at 100yds and 13 KO slugs were better than all the others. I am hoping to find a proper hammer spring for my current one and see that power again out of this one.

Pellets are definitely weird. What I’ve experienced in the last maybe four years has me done with painting them with a broad brush. Last year I was experimenting with a .25 FX pellet shooter for squirrel. Things were fine at 50 but horrible at 75 yards. Sped the gun up to slug speed and bingo, wound up with a 100 yard non 33.95 pellet gun for the season.
