I have tried the tsx in other calibers but here were I hunt is only deer so there is really no need for them.I used them once on a out of state wild boar hunt and they worked fine out of a 270wsm,shot a 185 lb boar in the throat at 150 yds.
I haven't even hunted with my 243 in years because I have a lot of different calibers and like to try something different every time I go,last year I used a 25/06,308,708,sav muzzleloader to take deer here,and even got one with a bow.
Below is the load I use in the 243,I only get 3192 fps,it has a 22 in barrel.I like showing this target,it is the best I have gotten with the 243,have gotten some close but not this close.Think its the shooters fault tho.
