Make do

First question I know that I will probably get roasted but I got to know. Rule book says "Both revolvers may be cocked at the same time but must be shot one at a time to facilitate scoring" So if telling if you hit or not is not a problem can both be shot at once. Ok here is the set up. 5 knock down plates 10 rounds extra to be dumped on a rifle plate. I figure why not shoot both a once at each knock down (fun to just point and shoot) because I thought I was bound to hit at least once. Similar to what the fast shooters do shooting at each plate a number of times even as it falls. So the scoring was easy to tell if all five plates were down for scoring. Only problem that I can see is on the fifth plate did it go down with the first revolver or second because if it is the first then it is a miss on the rifle target. But the fast shooters are the same way hard to tell if it was the first or following shot because if it was the following shot then it should of been on the rifle target and a miss. Second question - set up is two plate racks at 90 degrees to each other to be shot from two windows very close and at 90 to each other - The windows are marked b and c. It says "engage pistols racks from B and C any left standing can be made up with the shotgun". B and C are basically on top of each other. Being so close together I can put one foot in B the other in C and easily view both plate racks. Can I put one pistol out the B window and one out the C window alternating (for fun) rack B and then C?

The call was dropped gun. I don't think I can blame the prop. Prop had two cutouts one for the barrel and one for the stock. Both were rounded, so if you didn't put the barrel into the cut out it would slip to the side and fall same with the stock. I hit the stock cutout but missed ever so slightly the barrel cutout. I was just curious that the gun only fell half way to the ground (only the tip of the muzzle touching the ground) and it stayed perfectly pointed in the same direction I put it. After all 10 seconds is 10 seconds

Hand was off the gun - but next time I will shout I meant to do that

Rifle was open and empty, and didn't break the 170. What comes to mind is sometimes we stage rifles vertical with the butt touching the ground so it cant be considered dropped by just it touching the ground. Some people I have seen have let go of the rifle a little early and it drops butt down but by luck it comes to rest vertical against the prop where it was supposed to be staged, so there must be some additional considerations. I have also seen where a person sets down a rifle and it bounces into the air and by chance lands back on the table but not where they set it down. In both cases the rifle wasn't considered dropped. So what I would like to know what combination of things must happen to consider it dropped.

Trying to learn all the nuances to the rules here. Finished with my rifle and was setting it down on a cradle the barrel slipped off and nose dived into the dirt the butt stayed in the rear of the cradle in the air (mainly because of the long barrel), leaving only the muzzle touching the dirt. The muzzle was pointed down range it just fell straight down with the butt remaining in the cradle. How do you decided when a rifle is dropped?
