havent shot 200 yards with these bullets yet. I have with the 295s and they grouped right at 1.5" @ 200.

300 yards is out of the question for me as i would never shoot that far with a muzzy. Its challenging enough with a centerfire LOL.

Ive some some lehighs in the past, but nothing recently.

Now i have tested some 300gr gold dots in my Optima without a sabot, using the bigger .500" speer and shooting them like a conical. Good results.
