One bullet that failed to expand when pushed by only 50g Blackhorn, and shot through carpet, plywood, and water jugs, placed at 25 yard, was the standard 250g XTP.
Now, the same 250g XTP pushed by 80g Blackhorn worked good.....
Check out the
Lehigh Controlled Fracturing bullet doing the same test, pushed by only 50g Blackhorn. Note the hydraulic shock, and how the bullet performed as designed i.e. the petals all busted off, and tore the jugs up. The Lehigh also works good when pushed by 80g of powder.
The
250g Hornady MonoFlex also worked quite well when only pushed by 50g of Blackhorn.......
