One wont work for all

[Kurt]

Since I got this new .40-65 I been working up loads and a alloy that will work for it and a temper that will hold the bullet with the least amount of distortion to it when fired and I have found a good mix for the .40-65 but I also found that the mix that worked good for the little .40 did not perform as well in the .45-90 that made me pile up the snow again I need something to keep my off the EZ recliner when the weather is bad.
What I found is the alloy that works good for the .40 diameter does not react the same shot in the .45 diameter. The photo, those bullets were shot with three different alloy mixes the top bullets are the .40-65 and the bottom were shot with the .45-90. All loads had the same wad stack and the same alloy for each group of bullets but the only difference was the powder load. The .40-65 had 60 gr of 2F OE and the .45-90 had 83 gr of 2F OE. 23 grains more then the .40-65 had and look at the land engravings. The .40's filled out the grooves better then the .45's This sort of makes me rethink what I will use in the .40 and 45's. When a hard alloy works in the PP 40's might not perform as well in the .45's
And here I blamed the rifle and conditions
