Here are two targets shot offhand at 50 yds with a Freedom Arms 475 Linebaugh 420gr WFNG over 25.0gr H110 (chronoed right at 1,300 fps).
The first target - 5 shots one after the other.

This target was shot over the course of about a month. Every time I went to the range I got out of the truck hung the target and shot one round cold.

I was shooting the 475 a lot back then -- couldn't do it today.
FWIW,
