I bough my TX200 HC .22 earlier this summer. So far I've tried everything you have and more. I've settled on the Crosman Hollow Points. I can hold a good pattern to the far edge of my range which is 65 yrs. Less than $7.00 per 500 pellets. I can live with that. No need to look any further. I also have a TX200 .177 MKIII. There is no comparison between the two in so many areas. The .22 is so much harder to shoot! You have to be RIGHT ON in guessing distance. The flatter trajectory of the .177 makes knowing the distance not as critical. Also the KICK of the .22 will throw your hold off more often. That being said I prefer to plink with the .22 over the .177. It gives me so much more satisfaction when you do everything right. I've put 3,000 or 4,000 rounds at least through my .22 using the Crosman Hollow Points. If you get your hold down and consistent 65 yrs is no problem at all. That being said I would never shoot Hunter Field Target with my .22 TX200 unless I had to.
