If you go on line you will find that many people state that .40/82 not to be a very accurate caliber, well to me this is just not the case at all. Having read Mike Venturinos book "Lever Guns" he aludes in there to an accurate recepie for .40/82 1886 Winchesters.
Any way a lot of people purchase Lymans plain base mold to load for these two old calibers and would seem only to enjoy mediocre results with smokless powders.
Well I enjoy tack driving accuracy fom both of my .40/82 rifles. What is the secret to success? well buy a custom 260 grain triple cavity mold from Steve Brooks molds. Ask him to make it just the same as he did for Mike Venturiino many years ago except in my case I asked him to cut it for Hordandy rather than Lyman gas checks.
.40//82 is very sensative about brass thickness at the mouth of the case. I haver found that only Bertram and Jamison brass will chamber easily in my rifles with bullets sized to .408" not .406". This combinationd using IMR SR4759 and CCI magnum rifle primers is my recepie to success. Give it a try and SR4759 is no longer available although I bought lots before it was discomntinued as its the best powder for the big black powner llever gun cartridges firing smokless, is not volume sensative and burns well even with large air gaps. Also XMP 5744 works almost as well but you do get some unburnt powder.
Hope this helps.
