40-70 and the dd patched

[Kurt]

Don,
With my .40-70 I could never find a load that would hold 3 MOA total size groups with the 1F or 1.5 with a lot of those shots in that group would be under 1 MOA at 200 with 3-4 out of 10 going out to 3 MOA with the last powder I was using was the express. The best loads I shot in the .40-70 was 2 and 3F EXP.
When the OE powder came out I went back through load development for this rifle and again the 2 and 3 F OE out performed the 1.5 OE. I think the .40-70 just needs a little harder push. Also the old Cartridge powder did not do well in this Shiloh.
I mostly just use 2F and 3F in all of my rifles anymore. Just lately for the CPA .40-65 getting it ready for Midrange and Silhouette matches from what little I have had time to work up loads for it I ordered Swiss 1.5, 2 and 3F and again the 2 and 3F does the best over 1.5. I think the .40,s in my case just shoot best with a faster powder, but this might change down the road when I get done with load tests for the .40.
