I took my MKII Target 5.5" with a Bushnell TRS25 on it and my newest aquisition, the .500JRH BFR.
I wanted to adjust the sight on the MKII and try out the JRH.
I started with the MKII and got it pretty close. This is a 10 shot group I fired with it at 50yds. I was shooting Remington Golden bullets, which I have about a 10% dud rate on, but they sure are cheap. The best I ever did with the iron sights on this gun with this ammo was 1.3" @25yds. I'm not sure what happened on the flyer, but I'm not ruling out the opposite of a dud. This goup is just over 1.1" throwing out the flyer. The squares on these targets are 1/2". I might try one click right next time out.

The BFR was more of a "get to know" session. Since I don't have a mold yet, I bought the cheapest jacketed bullets I could find. Speer 350gr JSP deepcurls for $21/50. I loaded these over 33gr of H110 in Starline JRH brass with CCI 350 primers. This should be good for around 1400fps for a SWAG. I had to crank the rear sight all the way down and to the right to hit at 12 o'clock with a 6 o'clock hold. 2 groups here at 25 yds. The one to the left is a sight adjuatment group under 2" for 4 shots. The first shot was about a foot high. The group to the right is about 1.7" for 5 shots. Not bad for no load work up an just getting to know it.

I'm going to put the taller sight on it and hope that heavy boolits shoot to the left. DOH I mean right!
