Since I got this gun I have been trying to find a load that was potent but that did not kill me to shoot it. The first load I tried was from Laser Cast bullets. I used their data for their 430 grain True Shot bullet with a gas check.
Here are the chrono results. I was not able to make it to max because the case would crinkle with that much powder in it. Wish I took a picture so you would know what I meant.
I also bought some 400 grain lead bullets and loaded them with Trailboss. Those were fun to shoot and were fairly accurate.
Here is the data.

I could not get the 430 grain load to group. I had a lot of vertical stringing. Part of it may have been me as the recoil from the bench was quite painful. I decided to try a more tame load that would still hopefully be effective on bears. I tried the Hornady 350 grain RNFP with Reloader 7. This load averaged 2.5 inches and while it still hurt to shoot it was not nearly as bad as the 430's. I am thinking of getting this gun ported.
Here is the chrono data from the 350's

I had two bullets left over from ruined cases with the 430 grainers I loaded them with RE7 as well and chroned them.

I also had to re sight in my open pistol after my friend added gas pedal for me. Here are the two groups I fired to confirm zero.

I was practicing drawing and aquiring the dot at 7 and 10 yards with this gun. The red dot is slowing me down a bit on the first shot but after that its much faster. My first shots were averaging 1.4 to 1.55 at 10 yards. I am still getting used to having an optic on a pistol. But its fun.
