Big fan of .50 as all-around calibre here....uses less powder than .54, .50 has flatter trajectory due to bullet weight (which can you throw further, a baseball or hardball?)....and .50 is just a deadly....on targets or deer size game...and as mentioned above..rifle weight is wholly dependent upon wood architecture and choice of B or C barrel weight...period. You can own a .40 that weighs more than a .60 or visa versa. Folks that say one weights more than another are missing all the variables. Good luck and good hunting !
