I'm trying to work up a load with 180gr Barnes TSX. I have a winchester model 70 with a 26" barrel. I am looking for a match load and am trying to find a good long range load.
Some people recommend the slow burning RL22 for 180gr 06, accuracy is supposed to be good and Nosler #6 has it as the highest speed of them all in 180gr. Never treid it myself but now that my Deep Curls are in I am itching to give it a try. RL22 shoots remarkably well (and fast) in my 6.5x55 with its hefty 140gr pills so I don't doubt that one bit.
If you want a long ranged match load might I reccomend Serria Match Kings instead, Serrias are in genral the most accurate bullets I have ever loaded and their ballistics are far better then the TSX or even the TTSX.
Nosler says 61gr is the max charge, but most people who I know that use 180gr say 59gr is the sweet spot. No need to hit max pressures since this is the fastest powder listed for the 06 pushing a whopping 2777fps with a 59gr charge and a staggering 2872fps at max (faster then some factory 300 Win Mag), which BTW is not max due to pressure but rather the limit of how far you can compress a load with RL22 114%
I cannot vouch for the accuracy of these loads since I live in whitetail country and have not need for anything heavier then my 165gr Game Kings which drop my game with an authority.
I have loaded TSX bullets in 30-06 before and there is not a world of difference between them and conventional bullets. Same rules apply, start low and work up, you will get a slight reduction in effective case capacity due to copper being slightly lighter then lead, and hence taking up more space in the case, that is why I listed the data for the slightly lower charge as well. I used starting load data from cup and core bullets working up my load with no pressure signs. BTW starting charge is listed at 57gr RL22 2682fps.
