if you have lost confidence in a bullet you should switch.i have had no problem with the sst/shockwave's for the 5 deer i've shot with them.this year i shot a deer with a
250gr. barnes tmz this was placed just like the sst's,just behind front leg in the lower
1/3 of the chest.this calm at the shot deer with the top of his heart gone and a broken leg still managed a 50yd. death run with no blood showing for 30yds.pretty common for a run and blood.after skinning this deer i really could'nt notice any more damage done by the barnes vs the sst's. the reason i was using the barnes is it's been the most accurate in the knight vision.i believe most deer are lost due to poor bullet placement not the bullet..........karl
