I tested the new 22 caliber 36 grain bullet from Barnes called the Varmint Grenade yesterday. I thought this would be a natural for my 222AI since I have been using 40 grain bullets. This rifle will shoot 3/8" groups all day long no matter which brand of 40 grainers you feed it. Results are on the target below. I used the same loading data for my 40gr loads. I did NOT do any further load development because I did not see any potential here. The sighter was shot with my regular 40 gr load to be sure everything was okay with the equipment. BARNES VARMINT GRENADE If anybody would like to test them I have 90 left so I will send you some for FREE!
