[QUOTE="IdahoJoe, post: 903425, member: 23980"] Coefficent of thermal expansion as mentioned earlier could be a problem but if you look at the numbers aluminum is around 22E-6/degree c and steel is around 14E-6/degree C but steel varies from 9 to 17 based on type. So that means ??? in one inch with a 90 degree f 50 c you would expand 0.00011 inches with aluminum and around 0.000065 with steel. I don't know your scope tube is aluminum and your receiver is steel so your wrong either way. how much do rings weight? Aluminum will save you about 2/3 of the total ring weight. [/QUOTE]
