RIP
Here is an interesting video about the .22 training rifle you may have used back in the day. Heavy for a .22LR, but designed to have the same functional characteristics and weight (around 10lb) of the M14 rifle.
GREAT video! Ours were the bolt-action that he spoke about. Mr. Parkhill wasn’t about to unleash a “semi-auto” onto a bunch of 16-18 year old kids, even though he trained us hard on safety. This has brought back so many great memories. I did pretty darn good in rifle club, earning my sharpshooter with several add-ons [forgot what they were called but were added to the bottom of my sharpshooter medal]
