La carga que le gusto a mi rifle son 35.5 granos de imr 4064 con punta barnes tsx de 53 granos, no medí la velocidad pero me da una trayectoria super tensa apuntado a 200 metros me dio un grupo de menos de una pulgada y tumba la silueta de 385 con solo apuntarle en el lomo. La combinacion de esa excelente punta a gran velocidad deja los venados fulminados incluso con tiros un poco comprometidos.

So I began with the Barnes data for the 50 grain XFB bullet and hoped that the 10 reduction in weight and the two relief grooves in the 45 TSX FB would cut me some lee way. Three shots at 10 grains Little Gun The max for the 50 grainers and no issues. I then put together six more three shot groups increasing the powder charge by .5 grain a go. This is at its maximum the same powder charge that I use with the 45 grain Hornady Hornet bullet. Again no issues. The Cooper doesnt seem to shoot this bullet very accurately though. Continued in next post.
