I have a marlin 30-30 with micro groove rifleing. I cast a 170 grain gas checked bullet and use 33.5 grains of W-748. As far as the 45-70 goes maybe someone else is better equiped then I to tell you. I will be picking my first 45/70 up tuesday night. Heading out to get dies for it today. Leaning towards IMR-3031 as I will be casting 405 grain hollow base bullets for it. Good luck, be safe, Bob

With my Marlin 45-70 and 405 gr Cast FP, I am using Unique for about 1200fps. I don't need to hunt bear or buff with it, just hogs and white tail so the way I am loading, it works fine
Marlin 45 carbine
