A freind gave me about 500 bullets for my hornet, in a green sierra bullet box. these bullets are only 30 grain hp, never seen any this light before, are they sierra bullets? they are a real pain to load because they are almost as short as wide. been using 33g and 35g data with lil-gun and 296 with little luck, paterns not groups. so I am thinking wrong powder for this light of bullet and mabye to fast. so I am considering getting some 3031 and making some 1200 to 1500 fps squirrel loads. whats your thoughts? rifle is a cz 527 1 in 16 twist, have plenty of 40 and 45 grain bullets that shoot wonderful with lil-gun at full velocity.
