A reader is curious. Bruce Potts offers some advice
A: The debate about the eco-friendliness of non-toxic ammunition continues. Lead-free .22LR ammo makes a lot of sense because a vast quantity of lead ammo is shot every year.
The trouble is the alternatives to lead are usually a lighter metal or sintered materia – for example, compressed copper as in this new CCI amoo – and is therefore much faster than standard 40gr .22LR ammo.
Over my chronograph the lead-free CCI ammo achieves a velocity of 1,842fps. This makes it loud and, in my guns, it is not particularly accurate.
The .22 centrefire may have a bad reputation for deer work, but with prudent bullet choice it is certainly up…
On the ammo box it says .22 LR subsonic are dangerous up to 1½ miles - can one of these…
Due to the light 21g bullet weight, it loses energy quickly – from muzzle to 30 yards teh velocity dropped from 1,842fps to 1,564fps.
I would like to see accurate subsonic lead-free bullets that are not too heavy and long so they stabilise in a normal .22LR barrel.
