This test was done this morning. It is true i mostly test using 80g of Blackhorn. However there have been several tests done using only 50g Blackhorn.
Most bullets tested, fail to expand when the load is 50g Blackhorn, is why the charge is mostly 80 grain.
Bullets that fail to expand when the load is 50 grain Blackhorn include the Deep Curl bullets, with the exception of the 250g. The TEZ bullets fail when the charge is 50 grain. The partition bullet fails when the load is 50 grain Blackhorn. The heavier XTP bullets all fail to work when the load is 50 grain.
Bullets that work when the load is 50g Blackhorn include Gold Dot bullets, Controlled Fracturing bullets, and the 250g Monoflex. The 350g BorLock, did expand some.
