According to my reloading manual I can load a 400 grain bullet in my 45-70 cases with 50 something grains of H335. I found 405 grainers at a MUCH cheaper price, what do I need to do to load up 5 more grains of lead in the nose of this cartridge.
If you can't fix it with a hammer, take it to a mechanic. will270win@aol.com ~Secret Select Society Of Suave Stylish Smoking Jackets~

    If it were me I'd say add .6 grains. Its just a mathematical percentage I figure should be right, but I'm not sure. Ryan.

    I wouldn't add any more powder at all. The additional bullet weight is less than a 2% change. To be on the safe side, as a matter of fact, you MAY reduce your powder charge by .1 or .2 grains, but that shouldn't be necessary. Finally, nothing gets reloaders in to more trouble than guessing, or getting advice from someone that you haven't yet found out how many fingers they have on each hand. That includes me.

    Always back off loads 10% whenever you make any change of componants then work your way back up to max, looking for signs of excess pressure. Five grains of bullet weight isnt much I'd work my way up to max and if no pressure signs appear, good to go.
