Over the past year and a half I've used a lot of Aguila Super Extra HV 40 gr coated, approx. 7,000 rounds. Started using the Aguila Pistol Match 40 gr uncoated within the past year, burned about 3,000 rounds. Been using ARMSCOR 36 gr HP coated for about four years, used a little less than 10,000 rounds, so far. Have several hundred rounds of CCI in my closet along with several other brands. The Super Extra HV has given the best results, almost perfect. ARMSCOR runs a close second. The Pistol Match is incredible in my single shot Anschutz rifle; has trouble cycling the semiautos until they warm up. My.22lr ammo is being used in two S&W Model's 41, two S&W Model's 422, a Hammerli Xesse Sport, a Ruger 10/22, several Rugers, Mk ii and Mk iii and the Anschutz rifle. I must be living right because I can not detect any of the guns favoring one ammo, of the three, over the other.
