Sorry for the delay, everyone.
I plan to shoot factory ammunition this weekend and will post my results. The first link has two photos from last weekend. The type of powder and load amounts are in the pictures. Only one group seemed promising this past weekend, but still not ideal, and we will try to shoot close variations to that again. I will also make sure everything is screwed down correctly and any other tips given here. The gun is 4.7 lbs without the scope, FYI. I believe the scope is around 18 ounces. I will also try to measure the velocity too.
All shots are from 100 Yards on a secure bench that is bolted down to the concrete. I am using a lead sled that makes it very easy for the shooter, and I have shot very well with other rifles on it—the same shooting procedure from the beginning. The last photo was the first six shots that went down the barrel over a year ago with factory ammunition. I adjusted the turret once after the first shot that went high, and the following five were left untouched. The 1/4 MOA could be left to interpretation from this photo as there were more than three shots. I apologize for that original statement, as it may not be correct. The important thing here is it shot more than well, IMO.

I would like to bring this gun on a Muley/prong horn combination hunt in the plains of Wyoming in late October. I hope to shoot a prong up to 300 yards, but I don't feel comfortable passing 100 yards with these inconsistent reload groups.
Suppose the Factory shoots pretty well again this weekend. I may stick with that until I figure out what's going on.
I wanted to see if the gun or the loads was the issue. Thank you for everyone's comments.
