Slavek they made another IM still kicking my on AZZ over selling, in mid 70's I bought a new tang safety varmint in 220 swift, I did not know at the time but Douglas made the barrels.When I sold that gun in the late 90's to buy my Winchester varminter in 220 swift I had run thru over 3K rounds of factory ammo and the gun would still shoot .75 !. The guy in NM that bought it says he is shooting a .5 with it today, I bought the slower 55gr Hornady custom ammo by the 2 and 3case lots from Lock,Stock and Barrel. My Winchester is as accurate but a hell of a lot pickier on ammo. The dam ruger would shoot what ever you could buy and cram in it good! Dam I miss that gun! very best winpoor
