When I was 14 I made my first firearm purchase. Worked several months to save up for a 20 ga. H&R. Shot many squirrels, rabbit, Doves and many other critters. Later got hold of a 30-30 barrel and it became my first deer rifle. It belongs to my son now. It was his first shotgun/deer rifle. Had to cut the stock to fit when he started using it and regret that. The original stock was walnut but I could only find "hardwood" when he outgrew the shorty.
First gun was a Marlin (I think) single shot 410 I got for Christmas when I was 12. This gun was stolen when Mom passed leaving our home vacant.
I now own a Springfield model 957 bolt, single shot 410 that was given to me by a family friend whose husband had passed away and a "Zulu rifle" converted to 12 ga. The 410 sits by the back door itching for a shot at squirrels raiding the fruit and nut trees and in its off time is ready with a load of #2 buck shot for 2 legged thieves. The Zulu I have never shot due to its age and the fact the firing pin is broke. It has family history and It sits proudly in the safe.
Regarding the video, In deer rifle mode the I can reload the H&R as fast (or faster) as a bolt gun using the same technique.
