A local distributor (Parks and Sons), that I have an account with has SR4759 in 12lb kegs for $152. I have been reading up on the stuff and it does sound promising. I mostly shoot medium case ex-military calibers like 308, 30-06, 303, 30-40K, 8x57, 8x56R, x54R, with some 45-70 on occasion. If I buy the big keg, I am gonna want to use it in all of these carts. Also have heard that it is tough to meter in a Uniflow or Lyman 55 measure. I have been using imr4350 in all, but am thinking about a change. Could go with 4895 too. Please help me deceide....DanM
