Went out yesterday and shot some of the Hevi-13 #7's out of my 870 Express 20 gauge. I shot at a taped 40 yard distance, in 82 degree weather and shot into a 12mph wind. It wasn't the greatest weather, but I had to get it done.
I shot these out of an IC .560 with wad catchers. 187 hits in the 10" circle on the first shot and 185 on the second. I am really impressed with these shells.

I also shot one out of my Rem SF choke and ended up with and got 158 hits.

This gun will be going to Kansas with me

I know I'll be shooting the Hevi-13's instead of the Nitros that this gun was setup for.
