Re: Load Max Claification
"My question is are these loads greater than the stated Sierra max of 41.3 safe?"
Anyone trying to answer that will probably lie to you about other stuff too. THE reason different sources show different maxs is they got different results in different rifles. Your's is different from their's so YOUR max may be more or LESS than theirs. Blindly going to a book max without proper load work up is foolish no matter what the books say.
The only way to find the actual max load in any rifle with the components you wish to use is to start low and increase the charge in perhaps .3 gr. steps. Go up until something comes apart and back off .6 gr.
