All:
I was able to go to Cabellas and look at the Hornady 9th edition of their reloadinig manual. Here is what the book says.

COAL= 2.390" However can this be shortened? Will not Magazine feed at that length. Just for general purposes I screwed down the bullet length to see what it would take to magazine feed that measurement is 2.2785".

Can these be shot like this?

Here are the specifics per the book.

Minimum powder throw is 20.2 grains
Maximum powder throw is 24.1 grains

I am using the minimum of 20.2 grains and loaded 100 rounds per the book using the COL of 2.390

I also loaded 20 rounds at 20.2 grains and COL of 2.2785.

Am I going to have to single load these only and remove the 20 that I loaded to 2.2785
