My Cimarron Win 73 repro is not doing well with the 200 gr lead slug, averaging 3 in or more at 50 yds and poor to miserable at 100. Could be at my old age, maybe I just can't shoot any more, but have had good look with a 66 repro in 44 WCF. I have read some folks are using slower powders and would like to hear from any of you that have had good luck with them. One U tube shooter mentioned 30 grains of 3031 behind a 250 lead slug but I would not consider trying that in my gun unless someone else had tried it. I try to make all my mistakes on the safe side..................If any of you have any experience with this give me some ideas to try. Thanks in advance as always for the good help I so often get on this forum. Would the heavier 250 gr cast be a better deal? Hope you all stay away from the virus. But we all wash our hands a lot playing with lead don't we ?...........................
