[QUOTE="Veteran, post: 2233614, member: 118038"] Here are some possible substitutes based on model burn rates ranked by relative burn rate. Not to say they will work perfect in your rifle, and you have to do safe load development starting low and working up cautiously, or using a model to formulate a safe program at safe pressures. For Varget Varget Highest in the .61 range N140 IMR4320 IMR4451 Win 748 Lowest in the .56 Range All of these are just a little slower than Varget. ============================ For H1000 RL25 fastest at .38's N560 H1000 --at .36's Ramshot Magnum RL26 Acc Magpro Slowest at .33's H1000 is in the middle of all of these. ======================================= For Retumbo Ramshot Magnum fastest at .34's RL26 Retumbo at .33's IMR 8133 slowest at around .3 Retumbo is in the middle more or less of these. Hope this is helpful in this time of shortage trying to find other powders that will work in your rifle. Enjoy load development. Necessity is the mother of invention...... [/QUOTE]
