shooting my new 22 BR pushing 52 fowlers at 3700+ fps and nailed a ghog at nearly 300 yds. saw the mist and heard the impact. held into wind so i felt good until i went to check the pig. WHAT THE H! he crawled into his hole! shot placement was good but not enough energy transferred, so i decided to add more ft-lbs. my 12 tw 22 BR one holes with 60-64 gr bullets using n540, so i loaded 60 bergers with same load and it printed one hole off bench, so load some, make a ballistic table and back to the field. to ensure the berger comes apart, i hollowpoint these bullets and this leaves a very thin opening and with other bullets using the j-4 jacket, they REALLY come apart. found a ghog staring at me 209 yds away. put the sightron 1/8 dot on his neck and sent it...WHHHAAAPPP! the impact was really loud so i knew he was done. sorry i can't post photos...the carnage was unbelievable! the bullet entered his neck and exploded taking out his spine and all entrails down to his/her tail...talk about overkill. he/she probably didn't weigh more than two lbs when intact. i'll have to consider using these bullets at longer range and bigger targets.
