Without exact measurements it's hard to tell anything. However the grease grooves on your bullets are textured, which dates them no earlier that the 1890's forward.

They are cannelured. That weight would put them in the 22 or 25 range?? Measurements would help. Tony

Measure the width of the bottom of the bullet in millimeters, with that measurement you could find out the caliber by using this "Millimeter to Caliber" converter.

A US dime's diameter is .705-inch. Your fired bullets are somewhat mis-shapened by impact damage, but comparing the diameter of their undamaged bottoms with the dime in your photo indicates they are .32-caliber. They look like the same bullet discussed in the What-Is-It? last week, here:

I tend to agree with Charlie P.'s suggestion in that discussion that they are .32 ACP (Automatic Colt Pistol) bullets. He posted a photo of a box of .32 ACP bullets showing some of them outside of the box. Please check the discussion at the link above.

According to The Cartridge Collector website, the first lead-bodied bullets which had a "reeded" body-groove (which is also called a knurled cannelure) were made in 1877.

Here's a photo of a .32 bullet (with dime for comparison) which I think matches your bullets.
