Sig Sauer Crux Copper-Plated .22 Cal, 14.66 Grains, Round Nose Pellets

All barrels shoot different, You just got to try them out in your own gun,
Two same brand guns will shoot different, I have been thinking of copper pellets as my land is full of lead , LOL,
I find a pellet that shoots good in my guns and its hard to change,
I got a Mutant with a Linstone barrel in 22 dam thing would shoot any pellet good, Even the piranha pellets.
I changed to a CZ barrel and its pretty picky, Loves JSB 16 and 18gr pellets , and that's about it.
You just got to try them, If some says they suck in there gun, They may be spot on in your gun.
