I did some load's in the lead free stuff best of all was the 140g TTSX . 500 to 600 yards for a deer is as far as I think I will go at this time . going for a bear this year maybe 300 yards . I would like to practice out to 800 to a 1000 yards . The 150g TTSX was not that bad but my 5 shot group from the 140 would be inside the 5 shot group of the 150g . My big question is .. out of a 7mm rm is the 140g TTSX to light for what I want to do ? I dont need to hear about the other bullets I live in a lead free zone and hunt in it so lead bullets are out of the equation.
