Long Range bullet for Texan?

[Texan]

 Haven't found the magic pill yet, I've had some descent 100 yrd groups with the Mr hollowpoint ammo and the same with the HighArch Hunters but when I surpassed 100 my groups blew up they were 200 &230 respectively haven't gone heavy yet as I wanted to keep some range capabilities ? Anyone have good success & with what ammo?

Hi
recommend contacting Nick Nielson at Nielson specialty ammo. 
He might have something for you. 
Nick is a great guy to deal with and I think he can help you out.
