Just because he needs a block and tackle to help lift the bolt handle after firing doesnt mean he has a "hot" load .......does it stubble???
Lets not exagerate,a 4lb hammer is probably sufficient .As I previously stated,I am wondering why lazzeroni can't obtain the same velocity with the 130gr robar coated tsx that this guy claims with the 150gr bullet.Both case capacities are comparable and the barrel length is the same,the coating is the same, yet this gun supposedly drives a 20gr heavier bullet faster.
