My first time shooting was a Cooey 22. Think I was 8-9yo. Absolutely my best open sight rifle ever.
First centre fire rifle I ever shot was a military Lee Enfield 303, which is also my most memorable. Shot my first and biggest WTD; 14 pointer that put 185lbs of meat in the freezer ( including ribs).
Don't reload either.
First long range shooting was during my military service. A 7.62 (308Win); L1A1 Self-Loading Rifle, also known as the SLR (Self-Loading Rifle), by the Canadian Army designation C1A1 (C1) (the one I used) or in the US as the "inch pattern" FAL. Produced by the Belgian armaments manufacturer FN Herstal. Back in my hay day I could shoot consistently 1MOA out to 600M. Wasn't a bad rifle for a general service rifle with post and peep sights.
Did hours and hours of shooting with the 22barrel insert. Absolutely hated humping this rifle around as it was a heavy beast.
