Continuing development with the .44-77.

[Kurt]

Sounds like the conditions weren't to good for testing loads, but those conditions could develop at a match also.
There is nothing wrong with using a .40-65 for midrange. I have had a chance to use mine at Rapids and Cadillac for midrange and I shot a 94 and I think a 96 cant remember for sure but on the last shot the front scope mount fell off with the scope dangling off the side LOL. That was on the 300 yard line.
The last Rapids you and I was at was the other time I shot the CPA .40-65 with the tight 4º lead and it held the 600 with 10 shots that Carol kept telling me to drop down 3 and I said I want to shoot a group to see how this rifle will shoot so I shot 10 rounds and I said after the ten rounds I will drop it 3 for you and shot 3 more shots for a small group and they went into a clover leaf.
So don't cut a .40-65 short if you don't have the confidence yet in the 77.

Here is the load I shot in that .40-65. It shot well here at home at 200 and held well at 600.
