Burned around 250 rounds up today at my 100 yard range. Rifle is a Contender Carbine with a laminated Revolution stock set to add some weight. Barrel is a new TC 23" 22 LR says "Match" on the barrel. Mounted a 10x42 SWFA on it and quickly got it sighted in at 100 yards. Today was windy and the wind kept switching from my right to almost head on still a bit from the right. Ammo, well I had a bunch of different stuff to play with and chose Aquilla pistol Match, Federal Automatch, Federal standard velocity, Federal Gold Medal Match, Winchester Expert HP, some Winchester HV HP, Remington Target. I shot 15 shot groups at a 50 foot three position smallbore rifle target (ten 1 1/2" black dots), did not adjust for wind just fired away and refined my zero. Now some of this ammo is over ten years old and what I was looking for is vertical spread and what the wind was doing. Of the bunch the Federal Standard velocity and the Remington Target were the worst. The "Match" labeled ammo was OK not special. Best was the Winchester Expert HP stuff! Even the Winchester HV HP stuff outshot the Match ammo. After figuring the wind out I was waiting for the breeze to pick up just so I could test my guess work and it became easy with the Winchester "Expert" HP's to keep them in the black on the fifty foot target at 100 yards which is 1 1/2 inches across. Plenty good enough to knock the pigs over at a match. What I figure is wrong with the match ammo is the lube has dried and flaked off so I will soon "grease" them with Crisco and see if it helps.
