Lol! The wife bought me another air rifle for Christmas...the Crosman Vantage NP in .22 caliber, and she had to suffer through some lame 10 yard shooting I did in the loft. I think I am just going to keep this one with the "irons", although I will be replacing the flimsy rear plastic sight it came with, with something I can attach to the 11mm dovetail slot...probably a peep of some sort.Congratulations on finding another episode of the wide world of shooting sports that will empty your wallet
Your are aware that you don't have to go to the range. You can shoot airguns in the house. I shoot in the garage- 15 feet or 25 ft on the diagonal. Depends on which car is in the garage. That's plenty for pistol practice. For rifles it's 10M (32.5ft) from the end of the kitchen to the fireplace mantle. At least it is when the wife's not around.
There are multiple target traps available. Problem is they need to have a metal back to handle pellets. They are noisy when hit and depending on the power of the gun can raise lead dust. Which you don't want in the house. My solution is to fill the trap with electricians duct seal. It's an oil based clay that never dries out. Stops the noise, and any chance of ricochet. About $3 a brick at Home Depot.
As for the iron sights on the rifle. Look at a set of aperture globe sights. Front and rear are circles. You just center the target dot in the middle. Or go with a tube style red dot. Ultradot are are my choice. Text me I have a Diana 75 that target rifle with adjustable buttstock and cheek piece that might be the answer. Don't move the sights move the rifle.
Only at 10 yards to get a feel for the gun, but will be stretching it out to 25 yards this weekend.
