Can someone tell you the history about the Remington Target Master Model 510 22 cal?

Answer 1

The 510 was a single shot bolt action 22 cal short, long, and long rifle with a long barrel (24-25") and was very accurate for a production rifle. It was the base version, but had upgraded cousins. The 511 had a five round clip, and the 512 (which I have) had a fifteen round tube magazine. (like most auto's) These were not high end Target Rifles like the Winchester 52, but are about the closest thing at a much more affordable price. There were over a half million made between 1939 and 1962. There is a date code, two small letters a the left rear of the barrel. (mine is k G = may 1960) The later models had grooves for scope while the earlier did not. You can find information at remington.com. I found the chart for the date code there as well. http://www.remington.com/library/history/firearm_models/rimfire/model_510.asp
