I took the time to test the Sierra Matchking 175 grain. Useing the gun from my previous post I set up at 50 yards ( which is about the average shot for the friend i loaded these for). Now i know there is no true fire test except to shoot an animal but here is what i used 3/4 oak board Milk jug stuffed with plastic bags then filled with water (the plastic bags are to act like the internals of a deer. If you dont think they are tough grab about 10 of them together and try to poke your finger through them) 3 phone books Before Picture After Picture It blew the phone books about 3 feet back Here is what is left of the bullet. Only went through one phone book and half way through the second. I have shot phone books at 100 yards with lighter faster bullets and they went all the way through 4 books so i think the water and bags really acted like a inside of a deer.
