...a pellet rifle I can shoot in my garage.
About 8 years ago I began researching the world of precision adult air rifles. I discovered things had come a long long way since I had owned my Daisy Red Ryder

To make a long story short, within a couple years I ended up selling some of my long guns to fund my new obsession and it is only recently I have returned to the
powder burner world. I can say with certainty that my
trigger time with the modern airguns have improved my ability in all aspects of the shooting world.
I won't dismiss the benefits of dry firing but launching
something downrange is definitely more fun! My present go to air rifle is a 14 shot repeater and will shoot 10 shot groups in the .3's at 50 yards which is pretty good in the air gun world. Hitting 20 9mm casings in a row is my present record at that distance

The level of concentration and attention to all the shooting fundamentals is just as intense and I can shoot hundreds of top quality match pellets for a few dollars...without hearing protection...or cleaning up empties...or disturbing neighbors (or the wife) and to boot I almost look forward to the squirrels terrorizing my garden :

and you'll never burn out a barrel!
I shoot off my dining room table, through a slight opening in my rear patio door and into a trap (cake pan lined with duct seal) at the back of my garage for
silent 25 yard practise. That's about medium range for my rifle and is far enough for me to have to compensate with elevation and for a 3mph breeze. In 5 years, the number of
focused trigger squeezes I've made with my .177 in practise and in competition have outnumbered my powder burner shots at least 50 to 1.
I think it has helped
me.
