A couple years ago at the Shootout I ran into the NECO rep and he showed me some sintered copper and tin solid bullets. They're offered on NECO's site for like 66 a thousand in 22 caliber from 42 to 55 grains.
Anyone out there used them? I want some feedback before plunking down the dough, on two things:
Accuracy compared to "normal" bullets?
Terminal ballistics on varmints? (Looking for something that will dump the energy in the animal without blowing out the other side).

Up hills slow,
Down hills fast
Tonnage first and
Safety last.
