I have an open mind towards them ,never used them ,the cost of a lot of these projs ,including some American brass Barnes @ $4.00 plus each is getting expensive ,ok if you are on an expensive safari ,I shot a buffalo with a Bertram 750 gr 577 bullet soft point ,entered the front inside shoulder exited at the pelvis ,about 4 feet ,was impressed with that . Would be interesting to see how they perform in 500 cals and up ,possibly the best dangerous game proj
