Hello Jaydog
What are you calling long range 200 to 500 yards or 500 to over 1000 yards ?
357 and 257 will go to 1000 yards with the right bullet, Forget BC is constantly changing with the weather in the same day in the same hour.
For long range work you will have to be theathered to your big tank, a tank regulator is a must.
I set the world recored at 1107 yards with a Texan 308 stock gun no parts were changed I used a 154 grain spire point bullet
leaving the barrel at 850 fps group was 1.25 moa on a 24 inch target which is under 13 inches 3 shot group.It was windy and my range is in the rocky mountains in New Mexico at 7600 feet above see level ,forget wind at ground you have to shoot the wind 200 yards above you on that day I had 6 different winds to shoot through , if you cant under stand wind and how to read it you will never connect at 1000 yards.
Hop this helps you in your quest to long range air gun shooting .

Hey dwjr, what's the theoretical max range with .50 cal Texan?

Hello Ghillie
.50 cal Texan should be able to go to 1800 yards with the right bullet but you will need a lot of elevation built into sight base to go the distance. You will have the barrel in the scope for 1800 yards L.O.L.
I love playing long range with air.

Hey David, oh wow, that’s a lot! I’m expecting my Texan coming to my doorstep tomorrow, can’t wait to give it a shot and play with the long distance shooting. Appreciate your answer!
