Bolt 1 is a Norinco JW15A, was my first firearm, cost $250 with a 6x scope. It's actually fairly accurate out to about 80m, more than good enough for plinking. Bolt 2 is a Howa 1500 Mini Action in .223 Bolt 3 is a 1956 Spanish M43 Mauser, safety tab is usually a good giveaway. I was going to take the bolt out of the .17HMR, but need to take the action out of the stock to get it out. Not sure on the Sako, I've only just recently started in the sport, still a lot to learn! Maybe someone else will have a better idea.
