Additionally, there are lots of .22 cal slugs on the market, and finding the right one for your gun should allow you to outshoot even the best .25 cal pellet shooter, when the wind comes up....

Thank you for the advice and tips, I am surprised that the .22 slug will buck the wind better than a .25! I do love .22, I have purchased .25 for more knockdown for pesting/hunting but I always grab the .22 first when a Starling shows up!  :o

.22 slug is not a lot different than a .25 slug.... and a lot better than a .25 pellet.... Look at the BC, that is the key....

It's been covered, but why is .257 superior to .308 in air guns? Looking at the NOE 308-106-FN the BC is superior to the 258-75-FN, both of which would be suitable for the corresponding caliber of Texan. Is this related to twist rate and projectile length? I'm sure BC doesn't tell the whole story. There are molds from other vendors that should also be suitable for either caliber, but I chose NOE for directly comparing BC values.

NOE's Ballistics Coefficients are calculated by their bullet design program, they have not been verified by chronograph.... The 75 gr.  in .257 cal has a slightly higher SD than the 106 gr. in .308 cal.... My bet would be that it also has a slightly higher BC.... Even if the calculated value for the 106 gr. is correct, the difference is so small as to make no significant difference in the trajectory or drift.... At the same velocity, the .308 will require about 40% more air per shot, and will have more recoil and report....

The bottom line, however, is use whichever combination is more accurate for you.... The ballistics are so close, accuracy trumps everything else....

Sorry for the delay in answering. I found that the 80gr .260 Ranch Dog sized to .2573 was the absolute best bullet out of my .257 condor. I shot at 1020fps and sub-moa was easy. First thing to do is size and weigh every bullet. I don't know if the .257 Texan barrel has a choke? If that is the case your on your own? Also, take the silencer off when trying. If your POI moves when you put it on look for clipping on the port of the baffles. I have a LSS and it was a Problem on my rifle.

I'm pretty sure all Texans come with an unchoked LW barrel.
